The positive effect of electromagnetic waves on the human body. Protection against radiation from household appliances

Electromagnetic waves - the inevitable companions of domestic comfort. They pervade the space around us and our bodies: sources of EM radiation warm and light houses, serve for cooking, provide instant communication with any corner of the world. The influence of electromagnetic waves on the human body today is the subject of heated debate. So, for example, in Sweden, "electromagnetic allergy" is considered a disease. Although the World Health Organization still classifies such an organism's reaction as a "possible disease." Among its symptoms are headache, chronic fatigue, memory disorders.

“In my two decades of work, I have not seen any cases of electromagnetic allergy,” says Nina Rubtsova, a doctor, a member of the international expert commission of the WHO Electromagnetic Fields and Human Health program. “But phobias associated with electromagnetic waves have developed in society.” Do we have reasons for them? And how to minimize the likely harm from exposure to radiation?

How does electromagnetic radiation work?

All operating electrical appliances (and electrical wiring) create an electromagnetic field around them, which causes the movement of charged particles: electrons, protons, ions or dipole molecules. The cells of a living organism consist of charged molecules - proteins, phospholipids (molecules of cell membranes), water ions - and also have a weak electromagnetic field. Under the influence of a strong electromagnetic field, molecules with a charge make oscillatory movements. This gives rise to a number of processes, both positive (improvement of cellular metabolism) and negative (for example, destruction of cellular structures).

Everything is ambiguous. In our country, studies of the influence of electromagnetic fields on humans and animals have been conducted for more than 50 years. After hundreds of experiments, Russian scientists have found that most affected are growing tissues, embryos . “It turned out that electromagnetic fields also affect the nervous and muscle tissues, can provoke neurological disorders and insomnia, as well as malfunctions of the gastrointestinal tract - explains Nina Rubtsova. - They are change both heart rate and blood pressure « .

The influence of the electromagnetic field cannot be characterized as unambiguously negative - electromagnetic radiation is used in physiotherapy for the treatment of many diseases: it can accelerate tissue healing and have an anti-inflammatory effect. How exactly the electromagnetic field from ordinary household appliances affects us and how harmful it is to a healthy person is a moot point, therefore it is prudent to shield sources of electromagnetic radiation wherever possible and try to minimize its impact.

So, all household electrical appliances are sources of electromagnetic radiation, and the higher the power, the more aggressive the field . It is most powerful in microwave ovens, refrigerators with a frost-free system, electric stoves and mobile phones. Relatively harmless is considered low-frequency radiation propagating from the mains of the house. The field radiates from the wires even when the circuit is open and no electricity flows through them, but is largely shielded by grounded conductive materials, such as the walls of a house. The magnetic component of electromagnetic fields is more difficult to shield, but it disappears when the appliance is turned off. The exception is electrical appliances with a transformer that are turned off but remain connected to the network (TV, video, etc.). More dangerous is considered high-frequency electromagnetic radiation, the sources of which are radio and television transmitters, as well as radars.

Electromagnetic radiation at home

“In residential premises, it is enough to correctly arrange household appliances: a bed and sofas, a dining table, that is, those places where we spend a lot of time, should not fall into their field,” explains Dmitry Davydov, an expert at Ecostandard, an independent environmental review company. - When moving away from the source of electrical radiation at a double distance, the field strength decreases by a factor of four. This is the easiest way to minimize exposure to radiation: for example, don't sit too close to the TV."

It is better to place a sleeping place no closer than 10 cm from the wall, especially in houses with reinforced concrete walls. Well, if the wiring has a third ground wire, you can also replace conventional wiring with shielded wiring. It is better if the wires and sockets are closer to the floor, and not at the level of the human belt, as is often the case. Electric heated floors generate a field of up to one meter above the surface, so it is best not to place them under the bed or in the nursery. However, this disadvantage can be compensated for with the help of shielding paints, wallpaper and fabric materials.

Induction cookers generate strong magnetic fields, metal-ceramic hobs are preferable. The most modern models of microwave ovens are relatively safe: now most manufacturers pay special attention to their high tightness. You can check it if you carry a sheet of aluminum foil in front of the door of a working microwave oven: the absence of crackling and sparks will confirm that everything is in order.

Electromagnetic radiation at work

For those who work a lot at the computer, there is a simple rule: there should be a distance of about a meter between the face and the screen. And of course, plasma or LCD screens are safer than cathode ray tubes. Radio and mobile phones are another source of radiation that we can't avoid. These are transmitter-receiver devices that we hold near our ears and allow the radiation to act directly on the brain. “The question of the degree of harmfulness of mobile phones is being discussed,” Ecostandard specialist Alexander Mikheev comments on the problem. – The power of electromagnetic radiation of a mobile phone is a variable value. It depends on the state of the communication channel "mobile phone - base station". The higher the signal level of the station in the place of reception, the lower the radiation power of the mobile phone. As a precautionary measure, you can suggest the following: carry the phone in a bag or briefcase, not on the belt or on the chest, use a handsfree headset, especially when long calls are needed, choose models of phones with the lowest radiation power, especially for children. Children under the age of 12 should not use a mobile phone at all.”

Electromagnetic radiation outdoors

High voltage power lines (HPL) are hazardous to health - it is forbidden to build housing under them, but you can pass under them. “There are many hypotheses that substantiate the harmful effects of power lines on our body,” explains Alexander Mikheev. “According to one of them, power lines ionize dust particles flying nearby, which, getting into the lungs, transfer their charges to cells, disrupting their functions.”

Many of us are frightened by the proximity of cellular antennas, which are sources of ultra-high frequency electromagnetic waves, with power lines. “According to the existing rules, it is recommended to place the antennas of transmitting radio engineering objects on separate supports, but placement on the roofs of buildings, including residential ones, is also allowed,” Alexander Mikheev continues. - The main radiation energy (more than 90%) is concentrated in a rather narrow "beam", and it is always directed away from buildings and above adjacent buildings. This is a necessary condition for the normal functioning of the communication system.”

As Ecostandard told us, although in theory these antennas can have a harmful effect on health, in practice there are no grounds for alarm: studies of the electromagnetic environment in the area where the antennas were located were carried out by specialists from different countries, including Sweden, Hungary and Russia. In 91% of cases, the recorded levels of the electromagnetic field were about 50 times less than the permissible level.

Electromagnetic waves that heal

A whole branch of medicine physiotherapy– successfully uses electromagnetic radiation for the treatment of various diseases. PhD, head of the Department of Physiotherapy and Rehabilitation at the Research Institute of Pediatrics and Pediatric Surgery of Rosmedtekhnologii, physiotherapist Lev Ilyin talks about how this happens.

“Let me remind you that many large molecules of our body are polar, therefore, as a result of exposure to a non-permanent magnetic field, metabolism, enzymatic processes are activated, and cellular metabolism improves. This allows the use of magnetotherapy for edema, treatment of joints and for resorption of hemorrhages. The action of low-power direct current pulses on brain structures contributes to a deeper and more restful sleep. Such electrosleep is an important part of the treatment of hypertension, neurasthenia, sleepwalking and some vascular diseases. In acute inflammatory processes, the well-known UHF is used - a device that generates an electromagnetic field of ultrahigh frequency with a short wavelength. The tissues of our body absorb these waves and convert them into thermal energy. As a result, the movement of blood and lymph is accelerated, the tissues are freed from fluid stagnation (common in inflammation), and the functions of the connective tissue are activated. The apparatus for UHF therapy also allows you to relieve spasms of the smooth muscles of the stomach, intestines, gallbladder, accelerates the restoration of nervous tissue, reduces the sensitivity of terminal nerve receptors, that is, it contributes to pain relief. It also reduces the tone of capillaries and arterioles, lowers blood pressure and reduces the heart rate.

Electromagnetic waves of various ranges are widely used in radar, radio meteorology, radio astronomy, radio navigation, space research, and nuclear physics. In physiotherapy rooms, during the operation of medical equipment, electromagnetic fields arise, to which the personnel are exposed.

It is known that the sources of radiation of radio waves are tube generators that convert DC energy into high frequency AC energy. In the working premises of radio and television stations, sources of high-frequency fields can be insufficiently protected transmitter units, separation filters and radiating antenna systems. Microwave fields have the most pronounced biological effect. It has been established that centimeter and millimeter waves are absorbed by the skin and, acting on receptors, have a reflex effect on the body.

Radio waves - electromagnetic fields of radio frequencies - are part of a wide electromagnetic spectrum with wavelengths ranging from a few millimeters to several kilometers. They arise as a result of fluctuations in electric charges. The higher the oscillation frequency, the shorter the wavelength. Decimeter waves, penetrating to a depth of 10-15 cm, can directly affect the internal organs. In all likelihood, waves and the UHF range have a similar effect. There are short, ultrashort (KB, VHF), as well as waves of high, ultra-high frequency (HF, UHF). Electromagnetic waves propagate at the speed of light waves. Like sound, they have a resonating property, causing coincident vibrations in an equally tuned oscillatory circuit. The magnitude of the field generated by the generators is characterized by both the strength of the electric field, measured in volts per meter (V/m), and the strength of the magnetic field, which is expressed in amperes per meter (A/m). The unit of intensity of irradiation by centimeter waves is the intensity expressed in terms of power flux density (the value of wave energy in watts incident on 1 cm2 of the body surface per second). The intensity of electromagnetic fields (EMF) in the room depends on the power of the generator, the degree of shielding and the presence of metal coatings in the room.

Pathogenesis

It has now been proven that the electrical energy absorbed by the body can cause both thermal and specific biological effects. The intensity of the biological action increases with increasing power and duration of the EMF, and the severity of the reaction mainly depends on the range of radio frequencies, as well as on the individual characteristics of the organism. Intense irradiation first causes a thermal effect. The influence of high-intensity microwaves is associated with the release of heat in a biological object, which leads to undesirable consequences (heating of organs and tissues, thermal damage, etc.). At the same time, when EMF is below the permissible level, a peculiar specific (non-thermal) effect is observed, manifested by excitation of the vagus nerve and synapses. When exposed to high and ultra-high frequency currents, a cumulation of the biological effect is noted, resulting in functional disorders in the nervous and cardiovascular systems.

Clinical picture

Depending on the intensity and duration of exposure to radio waves, acute and chronic forms of damage to the body are distinguished. Acute defeat occurs only in case of accidents or gross violation of safety regulations, when the worker finds himself in a powerful EMF. There is a temperature reaction (39-40 °C); there is shortness of breath, a feeling of ache in the arms and legs, muscle weakness, headaches, palpitations. Bradycardia and hypertension are noted. Severe vegetative-vascular disorders, diencephalic crises, attacks of paroxysmal tachycardia, anxiety, repeated nosebleeds, leukocytosis are described.

With chronic exposure, patients most often complain of general weakness, fatigue, decreased performance, sleep disorders, irritability, sweating, headache of indeterminate localization. Some are concerned about pain in the region of the heart, sometimes of a compressive nature with irradiation to the left arm and shoulder blade, shortness of breath. Painful phenomena in the region of the heart are more often felt by the end of the working day, after nervous or physical stress. Individuals may complain of darkening in the eyes, dizziness, weakening of memory, attention. An objective study of the nervous system in many patients shows vasomotor lability, increased pilomotor reflex, acrocyanosis, hyperhidrosis, persistent, often red, dermographism, tremor of the eyelids and fingers of outstretched hands, and revitalization of tendon reflexes.

All this manifests itself in the form of an astheno-vegetative syndrome of varying degrees of severity. Changes in the parasympathetic nervous system are among the most characteristic reactions of the body to the effects of microwave electromagnetic fields. They are expressed in arterial hypotension and a tendency to bradycardia, the frequency and severity of which depend on the intensity of exposure. Those working with microwave generators may experience violations of thermoregulation and other phenomena of vegetative-vascular or diencephalic pathology (subfebrile temperature, thermoasymmetry, double-humped or flat sugar curve), inhibition of skin sensitivity to ultraviolet rays is noted. In rare cases, diencephalic syndrome is observed.

The clinical symptoms of pathological changes in the cardiovascular system resemble a picture of neurocirculatory dystonia, more often of a hypotonic type; changes of a myocardial dystrophic nature are found in the myocardium.

Endocrine-metabolic disorders also appear against the background of functional disorders of the central nervous system. Often there are shifts in the functional state of the thyroid gland in the direction of increasing its activity. In severe forms of pathology, the activity of the gonads is disrupted (dysmenorrhea in women, impotence in men).

Exposure to radio waves is accompanied by changes in peripheral blood parameters, and their instability and lability are often noted. There is a tendency to leukocytosis or, more often, to leukopenia, neutropenia, relative lymphocytosis. There are indications of an increase in the number of eosinophils and monocytes in the peripheral blood and a decrease in the number of platelets. On the part of the red blood, a slight reticulocytosis is detected. Microwaves under especially unfavorable working conditions have a damaging effect on the eyes, causing clouding of the lens - microwave cataract. Changes may progress over time. Turbidity, revealed during biomicroscopy, is noted in the form of white dots, fine dust, individual threads located in the anteroposterior layer of the lens, near the equator, in some cases - in the form of chains, plaques and spots. When diagnosing occupational diseases, the syndromic classification of lesions by the microwave field, proposed by E.A. Drogichina and M.N. Sadchikova, distinguish vegetative, asthenic, asthenovegetative, angiodystonic and diencephalic syndromes.

General strengthening therapy with the use of sedatives and hypnotics is recommended. Antihistamines, small tranquilizers, glucose with ascorbic acid are shown; biogenic stimulants - tincture of ginseng, Chinese magnolia vine, eleutherococcus extract. With a combination of symptoms of autonomic dysfunction with asthenic syndrome, it is advisable to alternate intramuscular injections of calcium gluconate and intravenous infusions of glucose with ascorbic acid. In the case of an increase in blood pressure, antihypertensive drugs are indicated. With a combination of functional disorders of the central nervous system (asthenic syndrome with autonomic dysfunction) with changes in peripheral blood, vitamin B6 is prescribed. With a combination of functional disorders of the central nervous system (asthenic syndrome and autonomic dysfunction) with changes in peripheral blood, vitamin B6 is prescribed.

Working capacity examination

In the absence of a clear therapeutic effect, as well as in severe forms of the disease (sharp asthenia, pronounced neurocirculatory disorders, diencephalic insufficiency), after appropriate therapeutic and preventive measures, a transfer to a job not related to exposure to electromagnetic fields is indicated, a referral to a medical and social examination to determine the degree disability.

In prevention, systematic monitoring of the level of radio emissions, shielding of installations in order to protect workers from radiation and the use of personal protective equipment, preliminary upon admission to work and periodic medical examinations with the participation of a therapist, neuropathologist, oculist, determination of hemoglobin content in the blood, the number of leukocytes are important , erythrocyte sedimentation rate. Persons employed at work with sources of electromagnetic fields of radio frequencies (millimeter, centimeter, decimeter) are examined once every 12 months; when working with sources of electromagnetic radiation of ultra-high, high, low and ultra-low frequencies - 1 time in 24 months. Additional medical contraindications for employment with currents of high and ultrahigh frequencies are severe autonomic dysfunction, cataracts, drug addiction, substance abuse, including chronic alcoholism, schizophrenia and other endogenous psychoses.

Mechanism of EMR influence

The human body, like any organism on Earth, has its own electromagnetic field, thanks to which all systems, organs and cells of the body work harmoniously. Human electromagnetic radiation is also called a biofield. The visual representation of the biofield, which some people see, and which can be built by a computer with the help of special devices, is also called an aura.

This field is the main protective shell of our body from the influence of external electromagnetic fields. When it is destroyed, the organs and systems of our body become easy prey for any disease-causing factors.

If other sources of radiation, much more powerful than the radiation of our body, act on our natural electromagnetic field, then it is distorted or even begins to collapse. And chaos begins in the body. This leads to disruption of the work of various organs and systems - diseases.

That is, for any person it is obvious that, for example, a buzzing transformer box or a powerful electric generator are dangerous, because they create a strong electromagnetic field around them. Safety time and distance standards have been calculated for workers when they are near such devices. But here's what is NOT obvious to most people:

The same effect of destruction of the biofield occurs when exposed to weak electromagnetic radiation, if the body is under their influence regularly and for long periods of time.

That is, the sources of danger are the most common household appliances that surround us every day. Things without which we can no longer imagine our lives: household appliances, computers, laptops, mobile phones, transport and other attributes of modern civilization.

In addition, a large crowd of people, the mood of a person and his attitude towards us, geopathic zones on the planet, magnetic storms, etc. have a significant impact on us. (for more details see page ).

Among scientists, there are still disputes about the dangers of electromagnetic radiation. Some say that it is dangerous, others, on the contrary, do not see any harm. I would like to clarify.

The most dangerous is not the electromagnetic waves themselves, without which no device could really work, but their information component, which cannot be detected by conventional oscilloscopes.

It has been experimentally established that electromagnetic radiations have a torsion (information) component. According to the studies of specialists from France, Russia, Ukraine and Switzerland, it is torsion fields, and not electromagnetic ones, that are the main factor in the negative impact on human health. Since it is the torsion field that transmits to a person all that negative information, from which headaches, irritations, insomnia, etc. begin.

How strong is the impact of the technology around us? We offer several videos for viewing:

How dangerous radiation surrounds us? Visual demonstration:

Of course, these are far from all the dangerous items that we use on a daily basis. More information about radiation sources can be found on the page:

Effect of electromagnetic radiation on human health

Weak electromagnetic fields (EMFs) of high frequency with a power of hundredths and even thousandths of a watt are dangerous for a person because the intensity of such fields coincides with the intensity of the radiation of the human body during the normal functioning of all systems and organs in his body. As a result of this interaction, a person's own field is distorted, which contributes to the development of various diseases, especially in the most weakened parts of the body.

The most dangerous property of such effects is that they accumulate over time in the body. As they say: "a drop of water wears away a stone." In people who, by occupation, use a lot of various equipment - computers, telephones - a decrease in immunity, frequent stress, a decrease in sexual activity, and increased fatigue were found.

And if we take into account the development of wireless technologies and the miniaturization of gadgets that allow us not to part with them around the clock... Today, almost every resident of the metropolis, who is somehow exposed to mobile and Wi-Fi networks, power lines, electric transport, etc., is at risk around the clock. .

The problem is that the danger is invisible and intangible, and begins to manifest itself only in the form of various diseases. At the same time, the cause of these diseases remains outside the field of view of medicine. With rare exceptions. And while you are healing the symptoms with the achievements of modern medicine, our invisible enemy stubbornly continues to undermine your health.

The most affected by electromagnetic fields are the circulatory system, brain, eyes, immune and reproductive systems. Someone will say: “So what? Surely this impact is not so strong - otherwise international organizations would have sounded the alarm long ago.

Data:

Do you know that within 15 minutes after starting to work on the computer in a 9-10 year old child, changes in the blood and urine almost coincide with changes in the blood of a person with cancer? Similar changes appear in a 16-year-old teenager after half an hour, in an adult - after 2 hours of work at the monitor.

(we are talking about cathode ray monitors, which are gradually disappearing from everyday use, but are still found)

US researchers found:

  • in most women who worked on computers during pregnancy, the fetus developed abnormally, and the probability of miscarriage approached 80%;
  • brain cancer in electricians develops 13 times more often than in workers of other professions;

Effect of electromagnetic radiation on the nervous system:

The level of electromagnetic radiation, even without causing thermal effects, can affect the most important functional systems of the body. Most experts consider the nervous system to be the most vulnerable of them. The mechanism of action is very simple - it has been established that electromagnetic fields disrupt the permeability of cell membranes for calcium ions. As a result, the nervous system begins to malfunction. In addition, an alternating electromagnetic field induces weak currents in electrolytes, which are the liquid constituents of tissues. The range of deviations caused by these processes is very wide - during the experiments, changes in the EEG of the brain, a slowdown in reaction, memory impairment, depressive manifestations, etc. were recorded.

Effect of EMR on the immune system:

The immune system is also affected. Experimental studies in this direction have shown that in animals irradiated with EMF, the nature of the infectious process changes - the course of the infectious process is aggravated. There is reason to believe that under the influence of EMR, the processes of immunogenesis are disturbed, more often in the direction of their suppression. This process is associated with the emergence of autoimmunity. In accordance with this concept, the basis of all autoimmune conditions is primarily immunodeficiency in the thymus-dependent cell population of lymphocytes. The effect of high-intensity EMF on the body's immune system is manifested in a depressing effect on the T-system of cellular immunity.

Effect of EMR on the endocrine system:

The endocrine system is also a target for EMR. Studies have shown that under the action of EMF, as a rule, stimulation of the pituitary-adrenal system occurred, which was accompanied by an increase in the content of adrenaline in the blood, activation of blood coagulation processes. It was recognized that one of the systems that early and naturally involves the body's response to various environmental factors is the hypothalamus-pituitary-adrenal cortex system.

Effect of electromagnetic radiation on the cardiovascular system:

You can also note the violations of the cardiovascular system. It manifests itself in the form of lability of the pulse and blood pressure. Phase changes in the composition of peripheral blood are noted.

The influence of electromagnetic radiation on the reproductive system:

  1. There is a suppression of spermakinesis, an increase in the birth rate of girls, an increase in the number of congenital malformations and deformities. The ovaries are more sensitive to the influence of electromagnetic radiation.
  2. The female genital area is more susceptible to the effects of electromagnetic fields generated by computers and other office and household appliances than the male.
  3. Vessels of the head, thyroid gland, liver, genital area are critical areas of influence. These are only the main and most obvious consequences of EMP exposure. The picture of the real impact on each individual is very individual. But to one degree or another, these systems are affected by all users of household appliances at different times.

Effect of electromagnetic radiation on pregnant women and children:

The children's organism has some peculiarities in comparison with an adult, for example, it has a large ratio of the length of the head and the body, and a greater conductivity of the medulla.

Due to the smaller size and volume of the head of a child, the specific absorbed power is greater than that of an adult, and the radiation penetrates deeper into those parts of the brain that, as a rule, are not irradiated in adults. With the growth of the head and the thickening of the bones of the skull, the content of water and ions decreases, and hence the conductivity.

It has been proven that growing and developing tissues are most susceptible to the adverse effects of an electromagnetic field, and active human growth occurs from the moment of conception until about 16 years of age.

Pregnant women also fall into this risk group, since EMF is biologically active in relation to embryos. When a pregnant woman talks on a cell phone, virtually her entire body is exposed to EMF, including the developing fetus.

The sensitivity of the embryo to damaging factors is much higher than the sensitivity of the maternal organism. It has been established that intrauterine damage to the fetus by EMF can occur at any stage of its development: during fertilization, crushing, implantation, organogenesis. However, the periods of maximum EMF sensitivity are the early stages of embryonic development—implantation and early organogenesis.

Data:

In the Neurodiagnostic Research Institute in Spain in 2001, they found that in 11-13-year-old children who talked on a cell phone for two minutes, the change in the bioelectrical activity of the brain persisted for another two hours after they hung up.

The University of Bristol in the UK completed a study last year showing a significant increase in reaction time in 10-11 year old children who used a GSM mobile phone. Similar results were obtained by the Finns at the University of Turku, who observed a group of children 10-14 years old.

In the USSR, until the 90s, a large number of studies of the biological effect of EMF on the developing organism of animals.

It has been established that even low EMF intensities affect the embryonic development of offspring. The offspring of irradiated animals are less viable, developmental anomalies, deformities, lag in weight, dysfunction of the higher parts of the central nervous system (slow production and reduced ability to maintain defensive and motor-food conditioned reflexes), and a shift in the pace of postnatal development are observed.

EMF-irradiated adult animals are characterized by a decrease in the number of offspring, changes in the genital organs of females, disturbances in the development of the fetus, a decrease in the percentage of interbreeding, and statistically more frequently observed cases of stillbirth.

A study of the effect of EMF on the offspring of rats exposed to electromagnetic effects in parameters similar to what a human embryo receives when its mother talks on a cell phone showed that, compared with the control, the embryonic mortality of the offspring is statistically significantly increased, the mass of the thymus gland is reduced, and the number of developmental anomalies is increased internal organs, for the first 4 weeks of the postnatal period, the mortality of the offspring of rats of all experimental groups was 2.5-3 times higher than in the control, and body weight was lower. The development of rat pups also went worse: the formation of sensory-motor reflexes, the timing of the cutting of incisors lagged behind, in female rat pups formation was disturbed.

Since the 60s of the last century, the scientific and technological revolution began. It was at that time that the first computers, radiotelephones were invented, the first satellite communications were developed and launched. In parallel with these innovations, the number of sources of electromagnetic radiation that were common at that time increased: radar stations; radio relay stations; television towers. Around the same time, advanced industrial countries began to be interested in the effects of electromagnetic radiation on human health. Now electronics, without which we can no longer do, accompanies us around the clock both at work and on vacation. Televisions, microwave ovens, mobile phones, computers, on the one hand, help us, and on the other hand, they carry an invisible but certain threat to our health - electromagnetic smog - a set of EM radiation from man-made instruments and devices. Most people are exposed to EMFs of varying levels and frequencies on a daily basis. The greatest danger to humans is the influence of electromagnetic radiation with a frequency of 40 - 70 GHz, due to the commensurability of the length of EM waves with the size of human cells. Now it is no secret to anyone that a person is able to absorb the energy of electromagnetic waves of a large frequency range, which subsequently leads to heating of living structures and cell death. Scientists propose to recognize the impact of the electromagnetic field on human health as one of the most dangerous factors and take tough measures to protect the population of the Earth.

  1. Problem

Since the 60s of the last century, the scientific and technological revolution began. It was at that time that the first computers, radiotelephones were invented (the first mobile phones weighed about 50 kg and were carried in cars), the first satellite communications were developed and launched. In parallel with these innovations, the number of sources of electromagnetic radiation that were common at that time increased: radar stations; radio relay stations; television towers. Around the same time, advanced industrial countries began to be interested in the effects of electromagnetic radiation on human health.

The greatest danger to humans is the influence of electromagnetic radiation with a frequency of 40 - 70 GHz, due to the commensurability of the length of EM waves with the size of human cells.

At the beginning of the 21st century, the most high-frequency communication was communication with satellites (11 GHz) and although the power of the transmitted signal was high, only microwatts reached the Earth's surface. In 2009, mobile operators presented another surprise to city residents - by increasing the frequency of communication between base stations up to 25 GHz (to increase the amount of transmitted data and provide better mobile communications). Thus, the influence of electromagnetic radiation on the human body at frequencies of 40 - 70 GHz has once again increased dramatically and one can only hope that the results will not be very sad. The widespread use of electronic devices in the national economy began around the middle of the last century, but after 10 years, leading scientists realized that it would not be possible to use their advantages with impunity. After all, everything that is plugged into an outlet and conducts electric current is a source of an electromagnetic field, which is not harmless to the body. Over the past 20 years, the number of devices and devices using electricity in the world has increased thousands of times. Now electronics, without which we can no longer do, accompanies us around the clock both at work and on vacation. Televisions, microwave ovens, mobile phones, computers, on the one hand, help us, and on the other hand, they carry an invisible but certain threat to our health - electromagnetic smog - a set of EM radiation from man-made instruments and devices. Most people are exposed to various levels and frequencies of EMF on a daily basis, for example:

  1. all day you work with a personal computer that irradiates you at frequencies of 10 - 70 GHz with a very weak electromagnetic field;
  2. in the evening at home you are in EMF created by household appliances, etc.

As a result of experiments in the 60s, it was found that electromagnetic waves are able to interact with living organisms and transfer their energy to them. Now it is no secret to anyone that a person is able to absorb the energy of electromagnetic waves of a large frequency range, which subsequently leads to heating of living structures and cell death. Scientists propose to recognize the impact of the electromagnetic field on human health as one of the most dangerous factors and take tough measures to protect the population of the Earth.

That is why the problem of the impact of electromagnetic fields on the human body is relevant today.

  1. The influence of electromagnetic radiation on the human body

We are all full-fledged residents of the modern world, and we notice the accelerated pace of development of the electronic industry. First of all, this is due to the rapid technical and scientific progress all over the world. For ordinary people, such changes have resulted in the emergence of a large number of electronic equipment in everyday life. For example, every person at home can find a microwave, refrigerator, TV, washing machine and other useful devices, not to mention such trifles as a hair dryer, an electric shaver, even a shoe dryer consumes electricity. In just a short time, our apartments have turned from a zone of peace and comfort into concrete chambers with an increased level of electromagnetic radiation. But it is hardly possible to escape from an overabundance of EMR in the workplace, because according to statistics, about 30% of the population spends most of their working time at a computer. It has been established that the electromagnetic radiation of all devices on the planet, created by man, exceeds the level of the natural geomagnetic field of the Earth millions of times! The field strength increases especially sharply near power lines, radio and television stations, radar and radio communications (including mobile and satellite), various energy and energy-intensive installations, and urban electric transport. At the moment, all over the world, advanced research centers are conducting research on the influence of electromagnetic fields on the human body. The facts obtained have forced the World Health Organization to recognize the threat of the influence of electromagnetic fields as the main one for human health and life. Here are some of them: studies conducted by scientists from the Karolinska Institute in Stockholm showed that children under the age of 15 are 2.7 times more likely to develop leukemia when in a magnetic field stronger than 0.2 μT. And if the field is more than 0.3 μT, children get sick already 3.8 times more often. The results of their research were confirmed by scientists from the Swedish National Institute of Occupational Diseases, proving that the influence of electromagnetic fields of power lines leads to an increase in the number of cases of blood and brain cancer in children and adults. World Health Organization (WHO) statistics show that when working on a computer, children's vision deteriorates at a rate of 1 diopter per year. In a 10-year-old child, negative changes in blood and urine appear 15-20 minutes after the start of working on a computer, in a 16-year-old child - after 30-40 minutes, and in an adult - after 2 hours, bringing the composition of their blood closer to that of cancer patients . At the same time, negative changes also occur in the immune, endocrine and central nervous systems. A strong negative influence of electromagnetic fields of the computer is noted on the reproductive function of both women and men. Swedish scientists have found that pregnant women working on a computer are 1.5 times more likely to have miscarriages and 2.5 times more likely to have children with congenital disorders of the central nervous system and heart disease. Therefore, it is strictly forbidden for pregnant women and breastfeeding mothers to work on computers, and women who are about to become pregnant are recommended to minimize the time of working with a computer or to completely abandon it 2-3 months before the proposed date of conception of a child. There is a direct relationship in the development of malignant tumors in those people who constantly work with video display terminals, radiotelephones or radio transmitters. So, among the American policemen, a high number of brain cancer cases was recorded and the reason for this was the harmful effect of the electromagnetic fields of radio transmitters, which they constantly used.According to the experts of the World Health Organization, the result of prolonged exposure to electromagnetic fields, even a relatively weak level, which has been proven by studies conducted in a number of countries, can be: cancer, behavioral changes, memory loss, Parkinson's and Alzheimer's diseases, sudden death syndrome of an apparently healthy person ( more often this is observed in the subway, trains or near powerful electric power plants), inhibition of sexual function, an increase in the number of suicides in large cities and many other negative conditions. The most dangerous effect of electromagnetic fields for a developing organism in the womb, children, and people prone to allergic diseases.

  1. Interaction of electromagnetic radiation with the human body.

Questions often asked when talking to people are:

  1. Is electromagnetic radiation really harmful?
  2. how exactly the process of exposure to electromagnetic radiation on the human body occurs;
  3. why exactly over the past three to four years, electromagnetic smog has become the number 1 threat in the world.

Let's look at how electromagnetic energy can interact with the human body in general. Scientists have identified several types of exposure to electromagnetic radiation on humans.

First, the human body is sensitive to the electric current flowing through the body. Such an influence is exerted on a person by any electrical device that creates a powerful magnetic field (hair dryer, power lines, household appliances). For example, being in a subway car, a person is inside a strong magnetic field, which causes electric currents in the body, which pose a serious danger to human health. It is against this type of exposure to electromagnetic radiation that public organizations that protect human health are fighting, tactfully keeping silent about other, much more harmful, types of effects of electromagnetic radiation on the human body.

Secondly, certain trace elements in the human body are able to absorb electromagnetic energy of certain frequencies from the external environment. We can observe this effect when food is heated in a microwave oven - electromagnetic radiation of high frequencies (2.4 GHz) resonates with water molecules in food, transferring energy to it and heating it. In the same way, various structures in the human body absorb electromagnetic energy from EMP in a huge range of frequencies. It turns out that all human-made electronic devices in one way or another interfere with the human body to perform its functions.

But the most dangerous is the third type of influence of electromagnetic radiation. Everyone knows that a person consists of the smallest living structures - cells. Inside each cell, chemical processes take place that determine the emotions and thoughts of a person at any given moment in time. As a result of certain chemical reactions, human cells produce an electrical current necessary for communication between cells and the nervous system and the proper performance of the functions of the human body. Electric currents, in turn, create an electromagnetic field around each cell, and merging from all cells together form an electromagnetic field (aura) around a person at certain frequencies (40-70 GHz). And if a person is exposed to external electromagnetic radiation at these frequencies, the power of which is above a certain level, then the person's own electromagnetic field is destroyed, as a result of which disturbances occur in chemical processes in human cells. As a result, it turns out that even a small electromagnetic radiation leads to serious disorders in the human body, weakens the immune system and is the cause of all kinds of diseases.

  1. Health risks of the microwave oven.

In the process of life, a person is constantly in the zone of action of the electromagnetic field (EMF) of the Earth. This field, called the background, has a certain level at each frequency that does not harm human health and is considered normal. The natural electromagnetic spectrum covers waves with frequencies ranging from hundredths and tenths of Hz to thousands of GHz. Power lines, strong radio transmitting devices create an electromagnetic field many times higher than the permissible level. To protect humans, special sanitary standards have been developed (GOST 12.1.006-84 regulates the impact of electromagnetic radiation on humans), including those that prohibit the construction of residential and other facilities near strong sources of electromagnetic radiation. Often more dangerous are sources of weak electromagnetic radiation, which acts for a long period of time. These sources include mainly audio-video and household appliances. Mobile phones, microwave ovens, computers and televisions have the most significant impact on the human body.

Over 90% of homes have Microwave Ovens (MW). Cooking in them is very convenient, fast, they are economical in terms of energy consumption. Most people do not even think about the safety of food cooked in a microwave oven for human health. Now there are studies that prove that cooking in microwave ovens is not natural, not healthy, not healthy and much more dangerous than we can imagine. Each microwave oven contains a magnetron that generates an electromagnetic field with a wavelength of approximately 2450 MHz (or 2.45 GHz). These waves, in contact with food molecules, change their polarity from + to - and back for each wave cycle, i.e. millions of times per second. As a result of the action of electromagnetic radiation on a substance, ionization of molecules is possible, i.e. an atom can gain or lose an electron - the structure of matter changes. Molecules are deformed, destroyed. However, microwave ovens are being manufactured, sold, and politicians ignore all the facts and evidence that microwaves are harmful. And people continue to use microwave ovens, unaware of their negative effects and health hazards. And given the fact that such a useful device can easily fit into any kitchen, the popularity of microwave ovens is only increasing every day. And official government agencies do not investigate the safety of microwave ovens.

Mobile phone damage.

Compared to any other household or office equipment, the mobile phone is more harmful because it creates at the moment of conversation a powerful stream of electromagnetic radiation directed directly to the head. Therefore, in the United States, which was the first to acquire mobile phones, a record surge in brain cancer has been recorded today. The electromagnetic radiation of the radio frequency range generated by the tube is absorbed by the tissues of the head, in particular, the tissues of the brain, the retina of the eye, the structures of the visual, vestibular and auditory analyzers, and the radiation acts both directly on individual organs and structures, and indirectly, through a conductor, on the nervous system ". Scientists have proven that, penetrating into tissues, electromagnetic waves cause them to heat up. Over time, this adversely affects the functioning of the whole organism, in particular, the work of the nervous, cardiovascular, and endocrine systems, electromagnetic waves have a detrimental effect on vision. Studies conducted in Russia have shown the negative impact of electromagnetic fields of a working mobile phone on the lens of the eye, blood composition and sexual function in mice and rats. Moreover, these changes were irreversible even after more than 2 weeks of exposure to them. If you use your mobile phone like a regular home phone, that is, for unlimited time, your immunity is seriously compromised.

Scientists warn: children who use mobile phones are at increased risk of memory and sleep disorders.

The effect of harmful electromagnetic radiation is similar to radio interference, the radiation disrupts the stability of body cells, disrupts the nervous system, causing headaches, memory loss and sleep disorders. Even the most ordinary non-working cell phone, if it's just lying next to your bed, can prevent you from getting enough sleep. The fact is that the electromagnetic radiation of a mobile phone, even in standby mode, negatively affects the central nervous system, disrupting the normal alternation of sleep phases. As it turned out, not only the electromagnetic radiation of the phone can pose a danger to human health. More recently, a new round of controversy on this topic was caused by events in China, where several people were injured by a lightning strike on a cell phone. In France, the meteorological service also warned all residents of the country that it is dangerous to use a mobile phone during a thunderstorm, because "they are conductors of an electrical discharge and can provoke a person to be struck by lightning." At the same time, you can not call on it, it is enough that it is turned on. In Sweden, they officially recognized the existence of an allergy to mobile phones and took an unprecedented step: all mobile allergy sufferers can receive a substantial amount from the budget (about 250 thousand dollars) and move to remote areas of the country where there is no cellular communication and television. In Russia, a national program to study the harmful effects of mobile phones on human health is to be adopted in September. However, “it must be understood that the study of long-term consequences will take more than one year. We will be able to put an end to the discussion about the degree of harmful effects of cellular communications only in a couple of decades.” Indeed, in the immediate vicinity of the most important human organs, when talking on a mobile phone, electromagnetic energy is emitted, the power of which is greatest in the near zone. It radiates energy of the same nature that rotates electric motors and cooks chicken in the microwave. Naturally, this energy penetrates the head, affects the brain and other human organs. Therefore, one should expect some kind of response from them to this impact. Moreover, this reaction can be either immediate, simultaneous with the impact, or delayed and manifest itself later, maybe after hours, days and years. In this case, it is necessary to take into account many factors: the age of a person, the presence of pathologies, his heredity, the physiological state in general and, especially, at the time of using a mobile phone, time of day, seasonal phenomena, temperature, atmospheric pressure, phase of the moon, the presence of drugs and alcohol in blood, type and brand of mobile phone, cellular standard, call duration, frequency of calls, number of calls per day, per month, etc., etc. It is also necessary to add: the size and shape of the ears, the shape and material of the earrings, the presence and composition of dust on the ears and behind the ears, ....

Believe me, this is not a joke ....

Today, mobile phone manufacturers on the devices themselves or in their passports warn users about possible harmful effects (they are finally forced!) And they must indicate the relative power level of electromagnetic radiation SAR (Specific Absorption Rate) measured in watts per kilogram of human brain mass. In most countries, the value of 1.6 W/kg is taken as the maximum permissible level. And now you will not meet cell phones with a SAR level of more than 2 W / kg. About 5 years ago, the first cell phones of the old standards had more powerful transmitters and significantly exceeded these levels, but now these values ​​​​are usually less than 1.5 W / kg, and the most advanced of them have this value below 0.5 W / kg. Expert of the Committee on Ecology of the State Duma of the Russian Federation, Candidate of Physical and Mathematical Sciences A.Yu.Somov scientifically proved that none of the 32 cell phones tested by him meets the stated criteria security.

Useful effects of a mobile phone. It is a myth?

Over the past few years, information has been floating on the Internet about the benefits of a mobile phone for people who are sick with certain diseases. Israeli scientists from Ben-Gurion University suggest that electromagnetic radiation from cell phones can be beneficial to health. Laboratory experiments have shown that in some cases it slows down the development of cancers. During the experiment, scientists transplanted cancer cells into laboratory mice, and then controlled the rate of development of the tumor node. Some animals were exposed to electromagnetic fields similar to cell phone radiation. An analysis of the results obtained showed that in animals exposed to electromagnetic radiation, tumors developed much more slowly than in those individuals that were not exposed to any effects. After the end of the experiment, the scientists concluded that prolonged exposure to electromagnetic fields had the same effect on the body of the experimental subjects as the vaccines used to prevent infectious diseases. Electromagnetic radiation causes damage to cells, which leads to the activation of the body's defense systems. And if at this moment a malignant tumor begins to develop in the body, then it is subjected to a powerful effect from the immune system, which slows down its growth. The study is good, but either something is left out, or the conclusions are drawn incorrectly. First, electromagnetic radiation damages ALL cells in the body, especially those located close to the source of radiation, so cancer cells die. Secondly, and most importantly, the immune system is also damaged. Therefore, as soon as the radiation ends, the cancerous tumor will grow even faster.

It can be concluded -electromagnetic radiation of a mobile phone affects the human body so strongly that even healthy cells die
For a full answer to questions about the dangers of EMR for human health, it will be necessary to conduct research for 15-20 years. During this time, the results of all experiments, of which several hundred are already planned, will be collected, the data will be combined into a common picture, in order to say with 100% accuracy exactly how electromagnetic radiation affects (or does not affect) human health.

The influence of a personal computer on the human body

Microwave ovens operate mostly for a short time (on average from 1 to 7 minutes), TVs cause significant harm only when located at a close distance from the audience. Against this background, the problem of PC electromagnetic radiation, that is, the influence of computers on the human body, is quite acute due to several reasons. The computer has two sources of electromagnetic radiation at once (monitor and system unit).

In addition, there are several secondary factors that exacerbate the situation, these include working in a cramped unventilated room and the concentration of many PCs in one place. The monitor, especially its side and rear walls, is a very powerful source of EMP. And although every year more and more stringent standards are adopted that limit the radiation power of the monitor, this only leads to the application of a better protective coating on the front of the screen, and the side and back panels still remain powerful sources of radiation. According to recent studies, the human body is most sensitive to the electromagnetic field located at frequencies of 40 - 70 GHz, since the wavelengths at these frequencies are commensurate with the size of cells and an insignificant level of the electromagnetic field is sufficient to cause significant damage to human health. A distinctive feature of modern computers is an increase in the operating frequencies of the central processor and peripheral devices, as well as an increase in power consumption up to 400 - 500W. As a result, the radiation level of the system unit at frequencies of 40 - 70 GHz has increased thousands of times over the past 2 - 3 years and has become a much more serious problem than monitor radiation.

  1. The consequences of working for a PC

The increased electromagnetic background largely ensures the impact of PC on people's health. As a result of prolonged work at the computer for several days, a person feels tired, becomes extremely irritable, often answers questions with unambiguous answers, he wants to lie down. Such a phenomenon in modern society is called chronic fatigue syndrome and, according to official medicine, is not treatable.

To date, at least 3 main types of computer impact on humans are known.

  1. The first of them is a violation of the functioning of some body systems due to sedentary work. This significantly affected the musculoskeletal, muscular, circulatory systems, etc.
  2. The next type of impact is the user's concentration on the monitor screen for a long period of time, that is, the damage to the computer can manifest itself in various problems with the visual system.
  3. The third and last type of interaction between computers and humans is harmful electromagnetic radiation, which, according to the latest research in this area, can be one of the most dangerous factors for human health.

And although over the past 10 years, manufacturers have significantly reduced the level of radiation from the front of the monitor, but there are still side and rear panels, as well as a system unit, the power and operating frequencies of which are constantly increasing, and therefore the level of dangerous high-frequency electromagnetic radiation is increasing. Although manufacturers make statements such as: harm to a computer is unfounded fiction, you must be careful with this electronic device, otherwise it may be at risk To your health .

Electromagnetic radiation has the greatest impact on the immune, nervous, endocrine and reproductive systems. The immune system reduces the release into the blood of special enzymes that perform a protective function, the system of cellular immunity is weakened. The endocrine system begins to release more adrenaline into the blood, as a result, the load on the cardiovascular system of the body increases. There is a thickening of the blood, as a result of which the cells receive less oxygen. In a person who has been exposed to electromagnetic radiation for a long time, sexual attraction to the opposite sex decreases (this is partly the result of fatigue, partly caused by changes in the activity of the endocrine system), potency decreases. Changes in the nervous system are visible to the naked eye. As noted above, the signs of the disorder are irritability, fatigue, memory loss, sleep disturbance, general tension, people become fussy. Under the influence of electromagnetic radiation, very serious diseases can occur. These are cases of blood clotting disorders, hypotension, dysfunction of the spinal cord, etc. Not a single scientist or doctor is now able to name all the consequences and symptoms. At the moment, this threat is considered much more dangerous than the impact of half-life products and heavy metals after the Chernobyl accident.

These are the consequences of the influence of electromagnetic radiation from a computer on human health.

As protective measures, one can name regular walks in the fresh air, airing the room, playing sports, exercising for the eyes (Appendix 4), following the rules for working at a computer (Appendix 1), working with good equipment that meets existing safety and sanitary standards. It is important to know the rules of working at a computer (Appendix 3)

  1. Our research
  1. Studying the influence of PC on attention and memory

In our time, life without a computer has become impossible, and it has become necessary in work and study. Not so long ago it was believed that since the impact of the computer is not visible, it means that the computer does not affect the body at all.

Our own research observations indicate that, most likely, the computer brings significant harm to health.

This work was carried out in two stages

Stage 1: questioning and analysis of questionnaires.

Object of study: secondary school students (from the fifth to the eleventh grade).

Subject of study:the provision of schoolchildren with computers, work at computers and the well-being of schoolchildren after working on a computer.

Methodical research procedure: this sociological study is not continuous, but selective, since not all children have a computer at home. It makes sense to interview several people from different classes in order to get a general detailed idea of ​​​​the issue under study.

Sample:

General population - students (from 5th to 11th grade) of a secondary general education school

The sample is 10 people: students of the 10th and 11th grades.

The age of the respondents is from 10 to 16 years.

Social groups - high school students.

Education - incomplete secondary.

Survey instrument: questionnaire.

Stage 2:

A study of attention in 10 schoolchildren before working on a computer, after one hour of work, after three hours of work according to the methods described in more detail in the relevant chapters.

Equipment and materials: attention research tables, stopwatch.

Discussion of the results of the survey(Annex 5)

79 people took part in the survey. 53 students (67%) have home computers. In addition, another 23 people use computers with friends or relatives (29%).

Total availability of computers in school is 67%!!!

22% of respondents answered - 2-3 times a week. 8.9% - occasionally, 69% - every day.

The answers to this question were very diverse: from 1 hour to look at the Internet to 8 hours.

The vast majority of respondents (96.2%) named all three answers, and only 3.8% of respondents said that they were not connected to the Internet. 30 hours - are fond of games, 51 hours - are engaged in educational activities, 50 hours - "sit" on the Internet

6. Do you know the rules of working with a computer

2 people, and this is 2.5%, do not know the rules for working with a computer. The rest answered that they knew, but they could not answer all our questions about these rules. Only 1 person correctly named the basic requirements for working at a computer.

60 people (76%) of the respondents answered that sometimes a computer helps (for example, in writing essays), and sometimes interferes with their studies.

Only 73% confidently answered that the computer affects health, 14% of children found it difficult to answer this question, and 13% believe that the computer does not affect health at all.

56% of students are concerned about their own health.

The sum of the specified percentages is not equal to 100, since it was allowed to mark several options.

Thus, in a small school, where children of not very wealthy parents mainly live, the number of computer users is 67%.

In addition, we conducted an additional study of the vision of students in grades 5-11. Of the 79 people, 22 people have poor eyesight (of which 15 are high school students), which is 27.8%. Approximately one third of them (16 people) associate visual impairment with long sitting at the computer.

2) Studying the influence of a computer on the stability of attention in schoolchildren in grades 10 and 11.

To perform this part of the work, we used the Landolt technique. It allows you to quickly and quickly enough, in conditions that ensure an increased interest of students in the content of tasks performed, to evaluate such indicators of attention as its distribution and stability at the same time. The last circumstance is important in the event that psychodiagnostics is carried out for adolescents who are extremely mobile and, as a rule, are not able to perform relatively uninteresting test tasks for a long time without distraction.

Stage 1 - control.

Methodology for assessing the distribution and stability of attention

using 25-digit one-color numerical tables

The stimulus material for this technique is 5 black-and-white 25-digit tables presented in fig. Numbers are randomly placed in the cells of these tables - from 1 to 25.

The procedure for applying the technique is as follows. The subject looks through the first table and finds it, indicating in it all the numbers from 1 to 25. Then, he does the same with all the other tables. The speed of work is taken into account, i.e. the time taken to look up all the digits in each table. The average time of work with one table is determined. To do this, the sum of the time required for all five tables is calculated, which is then divided by 5. The result is an average of work with one table. It is the numerical index of the child's attention distribution.

In order to assess the stability of attention using the same method, it is necessary to compare the time spent on viewing each table. If this time varies insignificantly from the first to the fifth table and the difference in the time spent on viewing individual tables does not exceed 10 seconds, then attention is considered stable. In the opposite case, a conclusion is made about insufficient stability of attention.

In addition, the difference in time when working with each subsequent cell is 11 seconds or more, which indicates a very strong fatigue. Of the 10 examined, all had a deviation from the norm after 3 hours of work on the computer.Thus, work on the computer affects the stability of attention in schoolchildren.

  1. Studying the influence of the computer on attention span

for students in grades 10 and 11.

To perform this part of the work, we used the Munstenberg technique. The technique is aimed at determining the selectivity of attention; it can also be used to diagnose attention concentration and noise immunity.

Instruction.

Among the set of letters there are words. The task is to find and underline these words as quickly as possible.

The study group consisted of 10 people. The study was carried out in three stages.

Stage 1 - control.

Stage 2 - after one hour of work at the computer.

Stage 3 - after three hours of work at the computer.

Discussion of the results

Stage 1 - control.

The average time spent on this job is 116.8 seconds. There were no missing words.

Stage 2 - after one hour of work on the computer.

The average time spent on this job is 136.5 seconds. Among the ten subjects, there were 3 words not found.

Stage 3 - after three hours of work on the computer.

The average time spent on this job is 185 seconds, i.e. over three minutes!

Thus, work at the computer significantly affects the mental processes of the student, in particular, the distribution and stability of attention.

4. Conclusions

1. Provision with computers even at school, where families usually have a small income - 67%.

2. The main harmful factors when working at a computer include: sitting position for a long time, exposure to electromagnetic radiation from the monitor, strain on vision, spine, overload of the joints of the hands, respiratory diseases, allergies, mental disorders.

3. 27.8% of students in grades 5-11 have poor eyesight, about half of them name the cause of visual impairment - prolonged "sitting" at the computer.

4. Work at the computer significantly affects the mental processes of the student, in particular, the distribution and stability of attention.

  1. Conclusion

In conclusion, we can say that many hypotheses are now being built about the impact of PC on health. It is even suggested that radiation causes cancerous tumors. But this has not yet been proven. BYE... But if this is proved in 5-10 years, then those who neglected the simple rules of their own safety will no longer be able to be helped. So many people need to think about the future.

Another hypothesis, also not yet proven, is that the computer affects the structure of the chromosome apparatus and leads to mutations. If this is so, then in 50-100 years there will not be a single healthy person left on Earth.

All this makes you think about what will happen next. And should you sit behind a glowing screen extra hours?

You can replace, repair a computer that has become unusable, but this does not happen to the body. Therefore, when buying another PC, think about what is more expensive for you and, in addition to the performance of your electronic assistant, take care of yourself. We need to take care of our health now so that it is not excruciatingly painful in the future.

This work aroused extreme interest among all the students of our school. Maybe someone in front of their classmates was cunning, saying that he had a computer. But, anyway, we did not expect such a supply of computers for a modern student at all.

The children of the whole school showed interest in this work, and in the process of research they themselves became convinced of the harm that the computer causes to the health and psyche of the child.

In addition, many have finally learned the rules of working at a computer, which makes our work even more valuable and relevant.

Attachment 1

Rules for working for a PC

1. Install an optical filter on the screen (if there is no built-in one).

2. The top edge of the monitor should be at eye level, and the bottom edge of the screen should be approximately 20 degrees below eye level.

3. The computer screen should be at a distance of 40-75 cm from the eyes.

4. The illumination of the screen should be equal to the illumination of the room.

5. When using the keyboard, the elbow joint should be at a 90 degree angle.

6. Every 10 minutes look away from the screen for 5-10 seconds (for example, towards the window).

7. Do not use the keyboard continuously for more than 30 minutes.

8. At the first sign of pain in the hands, immediately consult a doctor.

9. Organize work in such a way that the nature of the operations performed changes during the working day.

10. The duration of direct work with a computer depends on the availability of skills and the severity of the work and is: for schoolchildren - 1 hour with a break of 15-20 minutes; for adults - 4 hours with a break of 20 minutes every 2 hours.

Appendix 2

Here are some helpful tips:

1. Correct posture.When working at a computer, you need to sit directly in front of the screen, so that the top of the screen is at eye level. In no case should you work at the computer while lying down. You can not work at the computer while eating, and also sit stooped, otherwise the normal functioning of the internal organs will be disrupted.

2. Distance from eyes to monitorshould be 45-60 cm. If you play on a TV box, the distance from your eyes to the TV screen should be at least 3 m.

3. Protective equipment.If you or your child wear glasses, they should also be worn while using the computer. You can also use special protective glasses with lenses-filters.

4. Proper lighting.The room where the computer is located should be well lit. In sunny weather, cover the windows with curtains so that the monitor does not reflect.

5. Feeling good. You can not work at the computer in a painful or weakened state. This will further tire the body and slow down the healing process.

6. Observe the regime of work and rest.From time to time it is necessary to look at foreign objects in the room, and every half hour take a break for 10-15 minutes. When we watch TV or work at a computer, our eyes blink 6 times less than in normal conditions, and therefore are less often washed with tear fluid. This is fraught with drying of the cornea of ​​\u200b\u200bthe eye.

7. Special gymnastics.During the break, it is recommended to do gymnastics for the eyes. You need to stand at the window, look into the distance, and then quickly focus on the tip of the nose. And so 10 times in a row. Then you need to blink quickly for 20-30 seconds. There is another exercise: look sharply first up, then to the left, down and to the right. Repeat the procedure 10 times, then close your eyes and let them rest.

8. Nutrition. It is very useful to take vitamin A. It is responsible for the sensitivity of the eyes to bright light and sudden changes in the image. Just follow the instructions exactly: an excess of vitamin. And it doesn't lead to anything good.

Gymnastics for the eyes when working on a PC

After each exercise, it is advisable to close and relax your eyes (for one minute).

1) Frequent blinking of the eyes. Blink quickly and lightly for 2 minutes.Helps improve blood circulation.

2) Close your eyes tightly for 3-5 seconds, and then open your eyes for 3-5 seconds. Repeat 7 times.Strengthens the muscles of the eyelids, improves blood circulation, helps to relax the muscles of the eyes.

3) Exercise "trainer for the eyes": move your eyes in different directions (in a circle - clockwise and counterclockwise, right - left, up - down, figure eight). The eyes can be opened or closed as desired. If your eyes are open, then when moving your eyes, pay attention to the surrounding objects.Strengthens the muscles of the eyes.

4) With three fingers of each hand, lightly press the upper eyelids, after 1-2 seconds, remove the fingers from the eyelids. Repeat 3 times.Improves the circulation of intraocular fluid.

5) Exercise "close - far": attach a small picture or a coin to the window (or find any point on the window), look at the picture for 4-5 seconds, then the same amount at a distant object outside the window. Repeat 10 times.Relieves fatigue, facilitates visual work at close range.

Research work in physics "The influence of electromagnetic radiation on human health"

Purpose: To find out what effect electromagnetic radiation has on the human body. Or should we not be afraid of anything?

Tasks: 1. The influence of electromagnetic radiation on the human body. 2. Interaction of electromagnetic radiation with the human body. 3. Harm of microwaves, mobile phones and computers. 4. The consequences of working on a computer and how to protect yourself from EMR? 5. Conduct your own research.

The main sources of EMP 1 . Electric transport (trams, trolleybuses, trains,…). 2. Power lines (city lighting, high voltage, ...). 3. Wiring (inside buildings, telecommunications,…). 4. Household electrical appliances 5. Television and radio stations (transmitting antennas). 6. Satellite and cellular communications (transmitting antennas). 7. Radars. 8. Personal computers.

Relevance of the topic: We can no longer imagine our lives without cellular communications, microwave ovens, televisions, computers. Currently, the problem of the impact of electromagnetic waves on the human body is relevant.

A person is made up of the smallest living structures - cells. Chemical processes take place inside every cell. As a result of chemical reactions, cells produce current. Electric currents, in turn, create an electromagnetic field around each cell, and merging from all cells together form an electromagnetic field (aura) around a person. And if a person is exposed to external electromagnetic radiation, then the person's own electromagnetic field (aura) is destroyed, as a result of which disturbances occur in chemical processes in human cells. Aura of a healthy person. Aura of a sick person.

Cooking in microwave ovens is not natural, not healthy, not healthy and much more dangerous than we can imagine. Most people do not even think about the safety of food cooked in a microwave oven for human health. Is the microwave trendy?

There is a situation of global exposure to electromagnetic fields of the entire population.

Scientists warn: children who use mobile phones are at increased risk of memory and sleep disorders.

Cellular communications and children's health EmFs are especially dangerous for children. During the period of growth, the body is more sensitive to EMR than an already formed adult.

Harm to a computer Although manufacturers make statements such as: harm to a computer is an unfounded fiction, you must be careful with this electronic device, otherwise your health may be at risk. Under the influence of electromagnetic radiation, very serious diseases can occur. These are cases of blood clotting disorders, hypotension, dysfunction of the spinal cord, etc. At the moment, this threat is considered much more dangerous than the impact of half-life products and heavy metals after the Chernobyl accident.

Our research Studying the influence of the PC on attention and memory In our time, life without a computer has become impossible, and it has become necessary in work and study. Not so long ago it was believed that since the impact of the computer is not visible, it means that the computer does not affect the body at all. Our own research observations indicate that, most likely, the computer brings significant harm to health. Object of study: secondary school students Subject of study: provision of schoolchildren with computers, work with computers and the well-being of schoolchildren after working on a computer. Methodological research procedure: this sociological research is not continuous, but selective, since not all children have a computer at home. Survey instrument: questionnaire. This work was carried out in two stages

2) Studying the influence of a computer on the stability of attention in schoolchildren of grades 10 and 11. Stage 2: Study of attention in 10 schoolchildren before working on a computer, after one hour of work, after three hours of work according to the methods of Landolt and Munstenberg. Equipment and materials: attention research tables, stopwatch. .

Poll results: Among the students surveyed, boys have an average conversation time of 1 hour a day, girls - 2.5 hours.

A cell phone, a computer, and various household electrical appliances are like fire. As long as you use them carefully, follow all the rules, they bring benefits and joy. . Conclusion:

As protective measures, one can name: regular walks in the fresh air, airing the room, playing sports, exercising for the eyes, following the rules for working at a computer, good nutrition, working with good equipment that meets existing safety and sanitary standards. It is important to know the rules of working with a computer

Protection against e / m waves in the classroom.

Thank you for your attention!

With the constant development of high technologies, an increasing number of sources of harmful rays appear that surround man and nature from all sides. The issues of electromagnetic radiation and its influence on the human body are being discussed today by world-class scientists.

It is not possible to completely limit oneself from exposure to harmful radiation, but it is possible and necessary to prevent their excess, it is enough to understand what it is.

One of the proven facts of the impact of the electromagnetic field is its negative impact not only on human health, but also on his thoughts, behavior and even the psychological component. Scientists came to this conclusion after studying the long-term interaction of waves with the human body. The sources of these waves are all kinds of electronic devices, computer, WI-FI, power lines and much more.

Thus, based on research, experts have revealed the theory that developing diseases and pathologies in the human body take place due to the influence of rays from the outside. Moreover, decay products can even cause poisoning of body cells. Fortunately, a person can protect himself and his loved ones from harmful waves by knowing the elementary methods of protection against electromagnetic radiation.

Types of electromagnetic radiation are divided into radio waves, infrared (thermal) radiation, visible (optical) radiation, ultraviolet and hard radiation. IMPORTANT: in this case, the answer to the question “does visible light belong to electromagnetic radiation” is positive.

radio wave sickness

By the beginning of the 60s, specialists managed to discover a new trend in medicine - radio wave disease. The spectrum of distribution of this disease is very wide - 1/3 of the population. It cannot be said that in most cases a person is exposed to waves against his will. However, radio wave disease is already indicated by a number of symptoms, including:

  • headache;
  • dizziness;
  • increased fatigue;
  • sleep disturbance;
  • depression;
  • distraction of attention.

Since such symptoms apply to many varieties of diseases, diagnosing the above becomes extremely problematic. But, like any disease, radio wave is able to develop and progress.

As a result of its spread throughout the body, a person runs the risk of developing cardiac arrhythmias, chronic respiratory diseases, and even fluctuations in blood sugar levels. This happens through the destruction of the electromagnetic field of a person, affecting even the cells of his body.

This disease manifests itself in different ways depending on the organ or system that it affects:

  1. Nervous system - we are talking about a deterioration in the conductivity of neurons - nerve cells of the brain that are susceptible to electromagnetic radiation that affects a person. Thus, a deformation occurs in their work, which leads to a violation of conditioned and unconditioned reflexes, a deterioration in the functioning of the limbs, the appearance of hallucinations, and irritability. There are cases of suicide attempts against the background of a developing disease.
  2. Immune system - in this case, immunity suppression occurs. And the cells responsible for its protection are themselves susceptible to the influence of electromagnetic waves, thus creating an additional negative influence from all sides.
  3. Blood - electrical frequencies provoke the adhesion of blood cells to each other, contributing to the deterioration of blood outflow, the formation of blood clots. Thus, an extra release of adrenaline into the body can occur, which in itself is detrimental to health. There is no need to talk about a violation of the cardiovascular system - an obvious arrhythmia, the development of plaques in the heart muscle and other types of heart failure, as a negative effect of electromagnetic waves on the human body.
  4. Endocrine system - since this system is responsible for controlling the functioning of hormones in the body, the influence of electromagnetic fields speaks for itself. The derivative of this influence is the destruction of the liver.
  5. Reproductive system - often women are more affected by electromagnetic radiation than men. Possessing increased sensitivity to external influences, the female body is able to literally "suck" harmful radiation. This effect is especially dangerous during pregnancy. In the first weeks, the fetus is not strongly attached to the placenta, so there is a high probability of losing contact with the mother with a sharp release of radiation. With regards to later dates, the statistics are such that electromagnetic radiation affects the change in the genetic code of the child, the deformation of DNA.

Consequences of EMP

Radio wave sickness annually acquires new forms, expanding and progressing, depending on the number and level of radiation sources. Experts have identified a number of consequences not only individually, but also in a large-scale sense:

  • Cancer is no secret that oncological diseases manifest themselves under completely different conditions. However, scientists have proven an increase in the negative effects of electromagnetic radiation on cancer cells. Thus, studies in Japan have confirmed the presence of an increased risk of childhood leukemia in people whose bedrooms literally “glow” from the presence of electrical appliances and their components.
  • Violation of the psyche - in recent years, cases of deterioration in the perception of the surrounding world have become more frequent in those exposed to an excessive level of electromagnetic radiation. This is not only about the so-called classic symptoms, but also about the developing fear of EMR. Such fear often develops into a phobia, a person begins to panic at the thought that any emission of radiation can provoke painful sensations in one or another organ or part of the body.
  • Stillbirth - according to official data, today the risk of fetal death increases by 15%, provided that the mother is in constant contact with sources of electromagnetic radiation. In addition to stillbirth, the likelihood of developing pathologies in an unborn child increases, slowing down in development, premature birth, miscarriage. Such is the impact of electromagnetic radiation on human health and future generations.

In addition to the huge negative effect of electromagnetic radiation on the human body, these waves can poison the environment. The most susceptible areas include areas with a large accumulation of high-frequency power lines. Often they are located far from residential buildings, however, in individual cases, there is the presence of such power lines near settlements.

The flora and fauna are also exposed to the negative effects of harmful rays. In turn, a person eats irradiated animals and food products and, as a result, receives an additional dose of radiation-infected particles into his body. Such a process is extremely difficult to control due to factors beyond human control, but it is still possible to influence it.

Video: invisible enemy - electromagnetic radiation.

Data

To understand what constitutes the effect of electromagnetic fields on the human body, it is enough to familiarize yourself with the following facts:

  1. Changes in the blood and urine of a 9-year-old child 15 minutes after sitting at the computer coincide with changes in the analyzes of a cancer patient. Teenagers are subject to similar influence after half an hour of being near the computer. And an adult undergoes a change in the analyzes after 2 hours.
  2. The signal coming from a portable radiotelephone is able to penetrate the brain at a distance of up to 37.5 mm.
  3. Electricians are 13 times more likely to develop brain cancer than other professions. The level of the magnetic field in such workers is practically destroyed.
  4. A 13-year-old child who talks on the phone for about 2 minutes undergoes a bioelectrical brain change that takes place several hours after the conversation.
  5. Animals, even slightly irradiated with a dose of electromagnetic radiation, began to lag behind in development, acquired pathologies in the body, as with radiation.

The electromagnetic emission standards have the following meanings:

  • Radio waves - ultrashort (0.1mm-1m/30MHz-300GHz), short (10-100m/3MHz-30MHz), medium (100m-1km/300kHz-3MHz), long (1km-10km/30kHz-300kHz), extra long (more than 10 km / less than 30 kHz).
  • Optical radiation - ultraviolet (380-10nm/7.5*10V 14stHz-3*10V 16stHz), visible radiation (780-380nm/429THz-750THz), infrared radiation (1mm-780nm/300GHz-429THz) .
  • Ionizing electromagnetic radiation - X-ray, gamma. A more detailed table of calculations of EMP norms includes additional sources of propagation of harmful waves.

It is not possible to completely protect yourself from the effects of harmful waves. However, today there are a number of factors that can prevent the excessive influence of electromagnetic radiation on the human body:

  1. Acquisition of a special dosimeter. Such a detector will help to calculate the most dangerous sources of radiation by calculating the frequency of their waves and, as a result, reduce the time spent near such sources or eliminate them completely. Devices for measuring electromagnetic fields are available at any household store.
  2. Separation of radiation sources by area. It is not recommended to operate electromagnetic devices in a close radius between each other, otherwise their negative impact on the environment and the human body increases, causing maximum harm.
  3. Isolation of radiation sources. We are talking, for example, about the refrigerator. It is advisable to use it at a distance from the dining table. A similar situation with a computer or laptop: the distance to the place of deployment (sofa, bed) should be at least one and a half meters.
  4. Exclusion of toys with EMP. The electromagnetic effect of radio-controlled and electrical attributes for a children's room poses a serious threat to the health of an adult, and is extremely destructive for children. It is recommended to rid the room of EMP-radiated toys.
  5. Radiotelephone isolation. This technique is capable of emitting harmful waves to a radius of up to 10 meters. It is extremely important to remove such electronics as far as possible. This method of protection will protect against the main source of harmful radiation, since the radiotelephone operates 24 hours a day.
  6. Avoid buying counterfeit phones. The low price of such goods is due to the harmful radiation of electromagnetic waves per person in the first place.
  7. Careful selection of household appliances. In this case, we are talking directly about devices with a steel case.

In addition to the above factors, there are well-known simple methods of protection against electromagnetic radiation, the observance of which will also allow you to protect yourself from EMP, reducing the risk of exposure to the lowest indicator:

  • It is not recommended to be near a working microwave oven, since its waves have an extremely negative impact on the environment, if we take household appliances in comparison.
  • It is undesirable to be too close to the monitor.
  • Excluded being close to high-frequency power lines.
  • It is recommended to avoid an increased amount of jewelry on the body, which is desirable to remove before going to bed.
  • Approved the presence of electrical appliances, analog household appliances, appliances and wiring at a distance of 2 meters from the bed.
  • A minimum amount of time near working electrical appliances and similar equipment is recommended.
  • It is undesirable to find idle devices in the on state.

Often, people do not attach much importance to the harm that electromagnetic radiation can cause the most common household appliances and other factors surrounding them, because they are not able to see their waves. This feature makes EMR extremely dangerous for the life of all living things.

Having the ability to accumulate in the body, harmful rays affect the vital systems, manifesting themselves in a variety of diseases and ailments. The full scale of this problem will be seen by humanity a generation later - only then will a specific impact on the health of those who happened to live their lives surrounded by EMP sources be indicated.
