Continuous industrial progress and rapid development of science in the modern era have led to the widespread use of various household electrical appliances and electronic equipment. This creates great convenience for people in work, study and everyday life, and, at the same time, causes hidden harm to their health.

Science has proven that all consumer electronics, when used, generate electromagnetic waves of different frequencies to varying degrees. Electromagnetic waves are colorless, odorless, invisible, intangible, but at the same time they have great penetrating power, so that a person is defenseless against them. They have already become a new source of environmental pollution, gradually eroding the human body, negatively affecting human health, causing various diseases.

Electronic radiation has already become a new environmental disaster on a global scale.
To date, four International Congresses have been held around the world on the effects of low and ultra-low radiation on human health. The issue is recognized as so urgent that the problem of “electronic smog” has been put by the World Health Organization (WHO) in first place in terms of the danger of impact on human health. WHO considers “the current level of modern electromagnetic radiation and its impact on the population to be more dangerous than the effect of residual nuclear ionizing radiation.”

The International Commission on Non-Ionizing Radiation Protection of the countries of the European Union recommends that the governments of all states take the most effective preventive and technical means and measures to protect the population from the effects of “electromagnetic smog.” Special literature published in our country and abroad indicates the following manifestations of the harmful effects of electromagnetic radiation on the human body:

1. a gene mutation that increases the likelihood of cancer;
2. disturbances in the normal electrophysiology of the human body, which causes headaches, insomnia, tachycardia;
3. eye damage causing various ophthalmological diseases, in severe cases – up to complete loss of vision;
4. modification of signals sent by hormones of the parathyroid glands on cell membranes, inhibition of bone growth in children;
5. disruption of the transmembrane flow of calcium ions, which interferes with the normal development of the body in children and adolescents;
6. the cumulative effect that occurs with repeated harmful exposure to radiation ultimately leads to irreversible negative changes.

Biological effects of electromagnetic fields

Experimental data from both domestic and foreign researchers indicate high biological activity of EMF in all frequency ranges. At relatively high levels of irradiating EMF, modern theory recognizes a thermal mechanism of action. At a relatively low level of EMF (for example, for radio frequencies above 300 MHz it is less than 1 mW/cm2), it is customary to talk about the non-thermal or informational nature of the impact on the body. Numerous studies in the field of biological effects of EMF will allow us to determine the most sensitive systems of the human body: nervous, immune, endocrine and reproductive. These body systems are critical. The reactions of these systems must be taken into account when assessing the risk of EMF exposure to the population.
The biological effect of EMF under conditions of long-term exposure accumulates over many years, resulting in the development of long-term consequences, including degenerative processes of the central nervous system, blood cancer (leukemia), brain tumors, and hormonal diseases. EMFs can be especially dangerous for children, pregnant women (embryos), people with diseases of the central nervous, hormonal, and cardiovascular systems, allergy sufferers, and people with weakened immune systems.

Effect on the immune system

Currently, sufficient data have been accumulated indicating the negative impact of EMF on the immunological reactivity of the body. The results of research by Russian scientists give reason to believe that when exposed to EMF, the processes of immunogenesis are disrupted, more often in the direction of their inhibition. It has also been established that in animals irradiated with EMF, the nature of the infectious process changes - the course of the infectious process is aggravated. The occurrence of autoimmunity is associated not so much with a change in the antigenic structure of tissues, but with the pathology of the immune system, as a result of which it reacts against normal tissue antigens. According to this concept, the basis of all autoimmune conditions is primarily immunodeficiency in the thymus-dependent cell population of lymphocytes. The influence of high-intensity EMF on the body’s immune system is manifested in a suppressive effect on the T-system of cellular immunity. EMFs can contribute to nonspecific inhibition of immunogenesis, increased formation of antibodies to fetal tissues and stimulation of an autoimmune reaction in the body of a pregnant female.

Effect on the nervous system

A large number of studies carried out in Russia, and the monographic generalizations made, give grounds to classify the nervous system as one of the most sensitive systems in the human body to the effects of EMFs. At the level of the nerve cell, structural formations for the transmission of nerve impulses (synapse), at the level of isolated nerve structures, significant deviations occur when exposed to low-intensity EMF. Higher nervous activity and memory change in people who have contact with EMF. These individuals may be prone to developing stress reactions. Certain brain structures have increased sensitivity to EMF. Changes in the permeability of the blood-brain barrier can lead to unexpected adverse effects. The nervous system of the embryo exhibits particularly high sensitivity to EMF.

Effect on sexual function

Sexual dysfunction is usually associated with changes in its regulation by the nervous and neuroendocrine systems. Related to this are the results of work on studying the state of gonadotropic activity of the pituitary gland under the influence of EMF.

Repeated exposure to EMF causes a decrease in the activity of the pituitary gland

Any environmental factor that affects the female body during pregnancy and affects embryonic development is considered teratogenic. Many scientists attribute EMF to this group of factors.
Of primary importance in teratogenesis studies is the stage of pregnancy during which EMF exposure occurs. It is generally accepted that EMFs can, for example, cause deformities by acting at different stages of pregnancy. Although there are periods of maximum sensitivity to EMF. The most vulnerable periods are usually the early stages of embryo development, corresponding to the periods of implantation and early organogenesis.

An opinion was expressed about the possibility of a specific effect of EMF on the sexual function of women and on the embryo. A higher sensitivity to the effects of EMF of the ovaries than the testes was noted. It has been established that the sensitivity of the embryo to EMF is much higher than the sensitivity of the maternal body, and intrauterine damage to the fetus by EMF can occur at any stage of its development. The results of epidemiological studies will allow us to conclude that the presence of contact of women with electromagnetic radiation can lead to premature birth, affect the development of the fetus and, finally, increase the risk of developing congenital deformities.

Effect on the endocrine system and neurohumoral response

In the works of Russian scientists back in the 60s, in the interpretation of the mechanism of functional disorders under the influence of EMF, the leading place was given to changes in the pituitary-adrenal system. Studies have shown that under the influence of EMF, as a rule, stimulation of the pituitary-adrenaline system occurred, which was accompanied by an increase in the content of adrenaline in the blood and activation of blood coagulation processes. It was recognized that one of the systems that is early and naturally involved in the body's response to the influence of various environmental factors is the hypothalamic-pituitary-adrenal cortex system. The research results confirmed this position.

The earliest clinical manifestations of the consequences of exposure to EM radiation on humans are functional disorders of the nervous system, manifested primarily in the form of autonomic dysfunctions, neurasthenic and asthenic syndrome. Persons who have been in the area of ​​EM radiation for a long time complain of weakness, irritability, fatigue, weakened memory, and sleep disturbances.

Often these symptoms are accompanied by disorders of autonomic functions. Disorders of the cardiovascular system are manifested, as a rule, by neurocirculatory dystonia: lability of pulse and blood pressure, tendency to hypotension, pain in the heart, etc. Phase changes in the composition of peripheral blood (lability of indicators) are also noted with the subsequent development of moderate leukopenia, neuropenia, erythrocytopenia . Changes in the bone marrow are in the nature of a reactive compensatory stress of regeneration. Typically, these changes occur in people who, due to the nature of their work, were constantly exposed to EM radiation with a fairly high intensity. Those working with MF and EMF, as well as the population living in the area affected by EMF, complain of irritability and impatience. After 1-3 years, some people develop a feeling of internal tension and fussiness. Attention and memory are impaired. There are complaints about low sleep efficiency and fatigue. Considering the important role of the cerebral cortex and hypothalamus in the implementation of human mental functions, it can be expected that prolonged repeated exposure to maximum permissible EM radiation (especially in the decimeter wavelength range) can lead to mental disorders.

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 radio wave radiation are tube generators that convert direct current energy into high frequency alternating current energy. In the working premises of radio and television stations, sources of high-frequency fields can be insufficiently protected transmitter units, isolation 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 the broad electromagnetic spectrum with wavelengths from a few millimeters to several kilometers. They arise as a result of fluctuations in electrical charges. The higher the vibration frequency, the shorter the wavelength. Decimeter waves, penetrating to a depth of 10-15 cm, can directly affect internal organs. In all likelihood, UHF waves also have a similar effect. There are short, ultra-short (KB, VHF), as well as high and ultra-high frequency waves (HF, UHF). Electromagnetic waves travel at the speed of light waves. Like sound, they have a resonating property, causing coinciding oscillations in an equally tuned oscillatory circuit. The magnitude of the field generated by generators is characterized by both the electric field strength, measured in volts per meter (V/m), and the magnetic field strength, which is expressed in amperes per meter (A/m). The intensity unit of irradiation with centimeter waves is expressed in terms of power flux density (the amount of wave energy in watts incident on 1 cm2 of body surface per second). The strength of electromagnetic fields (EMF) in a 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 electrical energy absorbed by the body can cause both thermal and specific biological effects. The intensity of the biological effect increases with increasing power and duration of EMF action, and the severity of the reaction mainly depends on the radio frequency range, 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 injury, etc.). At the same time, when the 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 biological effect is observed, 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 damage occurs only in accidents or gross violations of safety regulations, when a worker finds himself in a powerful EMF. A temperature reaction is observed (39-40 °C); shortness of breath, a feeling of aching in the arms and legs, muscle weakness, headaches, and palpitations appear. Bradycardia and hypertension are noted. Severe autonomic-vascular disorders, diencephalic crises, attacks of paroxysmal tachycardia, anxiety, repeated nosebleeds, and leukocytosis are described.

With chronic exposure, patients most often complain of general weakness, fatigue, decreased performance, sleep disorders, irritability, sweating, and headache of undetermined localization. Some are bothered by pain in the region of the heart, sometimes of a compressive nature, radiating to the left arm and shoulder blade, and shortness of breath. Painful phenomena in the heart area are more often felt towards the end of the working day, after nervous or physical stress. Individuals may complain of darkening of the eyes, dizziness, weakening of memory and attention. During an objective examination of the nervous system, many patients experience vasomotor lability, increased pilomotor reflex, acrocyanosis, hyperhidrosis, persistent, often red, dermographism, tremor of the eyelids and fingers of outstretched arms, and revitalized tendon reflexes.

All this manifests itself in the form of asthenovegetative syndrome of varying severity. Among the most characteristic reactions of the body to the influence of microwave electromagnetic fields are shifts in the parasympathetic nervous system. They are expressed in arterial hypotension and a tendency to bradycardia, the frequency and severity of which depend on the intensity of radiation. Those working with microwave generators may experience disturbances in thermoregulation and other phenomena of vegetative-vascular or diencephalic pathology (low-grade fever, thermal asymmetry, two-humped or flat sugar curve), and there is a decrease in skin sensitivity to ultraviolet rays. In rare cases, diencephalic syndrome is observed.

Clinical symptoms of pathological changes in the cardiovascular system resemble the picture of neurocirculatory dystonia, often of the 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. Shifts in the functional state of the thyroid gland towards an increase in its activity are often observed. 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, and 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, slight reticulocytosis is detected. Microwaves under particularly unfavorable working conditions have a damaging effect on the eyes, causing clouding of the lens - microwave cataract. Changes may progress over time. Turbidity detected during biomicroscopy is noted in the form of white dots, fine dust, individual filaments 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 microwave field lesions proposed by E.A. is used. Drogichina and M.N. Sadchikova, there are vegetative, asthenic, asthenovegetative, angiodystonic and diencephalic syndromes.

General restorative therapy with the use of sedatives and hypnotics is recommended. Antihistamines, minor tranquilizers, glucose with ascorbic acid are indicated; biogenic stimulants - tincture of ginseng, Chinese lemongrass, eleutherococcus extract. When symptoms of autonomic dysfunction are combined with asthenic syndrome, it is advisable to alternate intramuscular injections of calcium gluconate and intravenous infusions of glucose with ascorbic acid. In case of increased blood pressure, antihypertensive drugs are indicated. When functional disorders of the central nervous system (asthenic syndrome with autonomic dysfunction) are combined with changes in peripheral blood, vitamin B6 is prescribed. When functional disorders of the central nervous system (asthenic syndrome and autonomic dysfunction) are combined with changes in peripheral blood, vitamin B6 is prescribed.

Work ability examination

In the absence of a clear therapeutic effect, as well as in severe forms of the disease (severe asthenia, severe neurocirculatory disorders, diencephalic insufficiency), after appropriate treatment and preventive measures, a transfer to work not associated with exposure to electromagnetic fields is indicated, a referral for a medical and social examination to determine the degree loss of ability to work.

In prevention, systematic monitoring of the level of radio emissions, shielding of installations to protect workers from radiation and the use of personal protective equipment, preliminary upon entry to work and periodic medical examinations with the participation of a therapist, neurologist, ophthalmologist, determination of hemoglobin content in the blood, and the number of leukocytes are important. , erythrocyte sedimentation rate. Persons working with radio frequency EMF sources (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 - once every 24 months. Additional medical contraindications to employment with high and ultra-high frequency currents are severe autonomic dysfunction, cataracts, drug addiction, substance abuse, including chronic alcoholism, schizophrenia and other endogenous psychoses.

Mechanism of influence of EMR

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 the biofield. The visual representation of the biofield, which some people see, and which can be constructed by a computer using 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 pathogenic factors.

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

That is, it is obvious to any person that, for example, a humming transformer box or a powerful electric generator poses a danger because they create a strong electromagnetic field around them. Standards for safe time and distance when staying near such devices have been calculated for workers. 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 its influence regularly and for long periods of time.

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

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

There is still debate among scientists 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 are 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 radiation has a torsion (information) component. According to research by 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 the negative information that causes headaches, irritation, insomnia, etc.

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

How dangerous is the radiation that surrounds us? Visual demonstration:

Of course, these are not all the dangerous items that we use every day. More information about radiation sources can be found on the page:

The influence of electromagnetic radiation on human health

Weak high-frequency electromagnetic fields (EMF) with a power of hundredths and even thousandths of a watt are dangerous for humans because the intensity of such fields coincides with the intensity of radiation from 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 areas 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, due to their occupation, use a lot of various equipment - computers, phones - a decrease in immunity, frequent stress, decreased 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 a metropolis falls into the risk zone, one way or another exposed to round-the-clock exposure to mobile and Wi-Fi networks, power lines, electric transport, etc. .

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

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

Data:

Did you know that just 15 minutes after starting to work on the computer, a 9-10 year old child’s blood and urine changes almost coincide with the 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 working at the monitor.

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

US researchers have found:

• in most women who worked on computers during pregnancy, the fetus developed abnormally, and the probability of miscarriage approached 80%;
• Electricians develop brain cancer 13 times more often than workers in 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. The mechanism of action is very simple - it has been established that electromagnetic fields disrupt the permeability of cell membranes to calcium ions. As a result, the nervous system begins to function improperly. In addition, the alternating electromagnetic field induces weak currents in the electrolytes, which are the liquid components of the tissues. The range of deviations caused by these processes is very wide - during the experiments, changes in the EEG of the brain, slowed reactions, memory impairment, depressive symptoms, 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 when exposed to EMR, the processes of immunogenesis are disrupted, more often in the direction of their inhibition. This process is associated with the occurrence of autoimmunity. According to this concept, the basis of all autoimmune conditions is primarily immunodeficiency in the thymus-dependent cell population of lymphocytes. The influence of high-intensity EMF on the body’s immune system is manifested in a suppressive 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 influence of EMF, as a rule, stimulation of the pituitary-adrenaline system occurred, which was accompanied by an increase in the content of adrenaline in the blood and activation of blood coagulation processes. It was recognized that one of the systems that is early and naturally involved in the body's response to the influence of various environmental factors is the hypothalamic-pituitary-adrenal cortex system.

The effect of electromagnetic radiation on the cardiovascular system:

Disorders of the cardiovascular system may also be noted. It manifests itself in the form of lability of 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, and an increase in the number of congenital defects 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 created by computers and other office and household equipment than the male genital area.
3. The vessels of the head, the thyroid gland, the liver, and the genital area are critical areas of exposure. These are only the main and most obvious consequences of exposure to EMR. The picture of the real impact on each individual person is very individual. But to one degree or another, these systems are affected by all users of household appliances at different times.

The effect of electromagnetic radiation on pregnant women and children:

The child's body has some features compared to adults, for example, it has a larger head-to-body length ratio and greater conductivity of the brain matter.

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

It has been proven that growing and developing tissues are most susceptible to the adverse effects of the electromagnetic field, and active human growth occurs from the moment of conception until approximately 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 EMFs, including the developing fetus.

The sensitivity of the embryo to damaging factors is much higher than the sensitivity of the mother's body. It has been established that intrauterine damage to the fetus by EMF can occur at any stage of its development: during fertilization, cleavage, implantation, and organogenesis. However, the periods of maximum sensitivity to EMF are the early stages of embryo development - implantation and early organogenesis.

Data:

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

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

In the USSR, until the 90s, a large number of studies were carried out on the biological effects of EMFs on the developing organism of animals.

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

Adult animals irradiated by EMF are characterized by a decrease in the number of offspring born, changes in the genital organs of females, disturbances in fetal development, a decrease in the percentage of crossbreeding, and statistically more frequent cases of stillbirth.

A study of the influence of EMF on the offspring of rats exposed to electromagnetic influence 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 was statistically significantly increased, the mass of the thymus gland was reduced, and the number of developmental anomalies was increased internal organs, during 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 was also worse: the formation of sensory-motor reflexes and the timing of incisor eruption were delayed; in female rat pups, development was impaired.

There are many ways to classify the health effects of electromagnetic radiation.

Here it is necessary to distinguish between biological changes (which are proven by experimental observations at the cellular level) and pathological effects (the generation or aggravation of diseases) proven by epidemiological studies.

The list of health effects of EMR presented here is actually only a small sampling of the large-scale studies currently reported in the scientific literature.

Biological Effects of Electromagnetic Radiation

Here are some of the biological changes research has shown to be caused by electromagnetic radiation (most recent data first):

Protein changes in the skin.

Ten women were asked to voluntarily participate in a study in which they were exposed to EMR (900 millihenry) via GSM cell phones for one hour. After the experiment, Scientists removed their skin cells for study in order to find any stress reactions. They examined 580 different proteins and found two that were significantly affected.

Irritability of brain cells.

DNA damage.

The German research group Verum studied the effect of radiation on animal and human cells. After the cells were placed in the electromagnetic field of a cell phone, they showed an increase in breaks in their DNA, which could not be repaired in all cases.

Lymphatic cancer and bone marrow cancer.

Researchers from the University of Tasmania and the University of Bristol studied reports from 850 patients who were diagnosed with cancers of the bone marrow and lymphatic system. They concluded that people living within 300 meters of high voltage power lines for long periods (especially during childhood) were 5 times more likely to develop these diseases later in life.

How does EMR work?

Some scientists previously believed that the only way radiation could produce harmful effects was if it was intense enough to cause a heating effect on tissue. (It was previously reported that talking on a cell phone for half an hour can raise the temperature of the brain in the part of the head where the device was in contact with it).

Subsequently, this theory was sharply condemned by many studies, which proved that the intensity of EMR is not enough to cause harmful effects.

The mechanisms by which electromagnetic radiation can trigger diseases are not yet fully understood, but experiments on this issue are being actively conducted.

DNA damage.

Our cells have mechanisms that allow limited repair of damage caused to DNA, but it appears that EMR can disrupt these mechanisms. Damaged DNA is implicated in the development of several diseases, including various types of cancer.

Host cell protective antiviral mechanism (interference) with Melatonin production.

Electromagnetic radiation is introduced into the production of melatonin, a hormone produced in the human body. Low levels of melatonin have already been shown to be associated with several diseases, including cancer. (Recent research indicates that seratonin production may also be affected by EMR).

Influence on intercellular communications.

Our somatic cells communicate internally and externally through electrical signals. These signals can be altered by electromagnetic radiation through the production of electrical currents within the body, causing changes in both cellular activity and cellular structures.

The harmful effects of electromagnetic radiation on health may depend on...

We don't have all the answers at this stage, but clues from various studies indicate that the health effects of EDS may depend on:

EMR intensity.

Exposure to strong electromagnetic waves can cause harm, even for a short period of time.

In one study, pregnant volunteers were asked to wear a device that measured the highest intensity (peak) EMR over a 24-hour period. The results indicated that higher peak EMR levels were correlated with higher rates of health damage (miscarriage).

Cumulative effect of EMR.

During the day, a person is exposed to electromagnetic radiation of various frequencies. For example, they can come from electric shavers and hair dryers, from car, bus or train equipment, household items such as heaters, ovens and microwaves, neon lights, home wiring, power lines, and the carrying and use of a cell phone. These are the most common sources.

The combination of these effects can overwhelm the body's defenses and defense mechanisms.

Duration of EMP action.

Numerous studies indicate that health damage begins to be noticeable only after many years of exposure to EMR, such as from high voltage power lines or cell phones.

Transience of EMF.

The body experiences greater biological stress from exposure to EMR from devices with changeable, fluctuating work cycles (photocopier, printer, etc.) than from constant work.

EMF frequency.

It is still not known for certain which types of electromagnetic waves cause negative health effects, but it appears that different frequencies cause different negative effects.

Signal overlay.

To produce an analog or digital signal, an electromagnetic wave can be modulated in various ways. Where the wave is used for communications (for example, radio, television, mobile telephony, etc.), the signal is superimposed on the frequency of the carrier. There is evidence that, in some cases, the signal component may be more harmful than the carrier's EMR.

The medical dangers of EMR are real.

The danger to our health caused by high levels of man-made electromagnetic fields is real. This is the general conclusion reached by many of a growing number of responsible scientists and health care professionals.

Luckily, there are many ways to protect ourselves and our loved ones before our health is affected.

1. Introduction

It's no secret that external electromagnetic radiation has a negative effect on the human body. The world around us is increasingly filled with computers, television equipment, cellular and radiotelephones, and various household appliances. People, being on the street, in transport, in their homes, are literally surrounded by wires. In large cities, places where man-made electromagnetic background exceeds permissible standards by tens and hundreds of times are growing at an alarming rate. When entering such zones, a person seems to find himself in a room with the sign “Caution! High voltage” and stays there for a long time.

When the space around a person is saturated with electromagnetic signals, the body experiences discomfort, leading to diseases of a wide variety of nature. This is due to the fact that a person located in an electromagnetic field is able to absorb electromagnetic energy to a certain extent, which depends on his own electrical properties, as well as on the nature of the electromagnetic field. Part of the active energy is reflected from the surface of the body, while part can be absorbed. The nervous system, cardiovascular system, brain, eyes, as well as the immune and reproductive systems are most susceptible to the influence of electromagnetic fields. EMFs pose a particular danger to children and pregnant women, since the still unformed child’s body has increased sensitivity to the effects of such fields. From all of the above, we can affirmatively say that considering the negative impact of electromagnetic radiation on the human body is relevant and significant.

2. A few words about electromagnetic radiation.

The English scientist James Maxwell, based on studying Faraday's experimental work on electricity, hypothesized the existence in nature of special waves capable of propagating in a vacuum. Maxwell called these waves electromagnetic waves. According to Maxwell's ideas: with any change in the electric field, a vortex magnetic field arises and, conversely, with any change in the magnetic field, a vortex electric field arises. Once begun, the process of mutual generation of magnetic and electric fields must continue continuously and capture more and more new areas in the surrounding space. Electric and magnetic fields can exist not only in matter, but also in vacuum. Therefore, it should be possible to propagate electromagnetic waves in a vacuum. Physicist Heinrich Hertz was the first to experimentally obtain electromagnetic waves. The simplest electromagnetic waves are waves in which the electric and magnetic fields perform synchronous harmonic oscillations.

External electromagnetic radiation has a negative impact not only on the human body, but also on the entire world around it. To date, the World Health Organization program “Electromagnetic fields and human health” has been approved and is being implemented. This problem is receiving close attention all over the world, because when the space around a person is saturated with electromagnetic signals, the body experiences discomfort, leading to a decrease in immunity.

Thus, the topic of the study was the study of the negative effects of electromagnetic radiation on the human body.

I decided to compose a questionnaire and conduct a survey to determine people’s awareness of the harm of electromagnetic radiation on the human body. 78 people took part in the survey. As a result of the analysis of the survey results, the following was revealed:

1. They know about the dangers of electromagnetic radiation and try to reduce its negative effects due to their knowledge - 75% of respondents

2. They believe that electromagnetic radiation causes harm, but it is insignificant for their health - 18% of respondents

3. Haven’t thought about this problem - 7% of respondents

4. They believe that the cardiovascular system and brain are most susceptible to the influence of electromagnetic waves - 71% of respondents

5. They believe that the nervous system is most susceptible to the influence of electromagnetic waves - 21% of respondents

6. They believe that the reproductive system, eyes, and hearing organs are most susceptible to the influence of electromagnetic waves - 8% of respondents

7. Know basic methods of protection from harmful radiation of electromagnetic waves - 36%

8. Possess incorrect knowledge in terms of protection from the negative effects of electromagnetic radiation - 64%

I came to the conclusion that people need more awareness about this issue.

3. Harmful effects of electromagnetic radiation on the human body.

Today, scientists in many civilized countries, including Russia, have come to the conclusion that the magnetic component of the electromagnetic field exceeding 0.2 microtesla (µT) is harmful to human health. But let's see what magnitudes of this tension a person has to face every day at the everyday level?

Take, for example, urban and intercity transport. So, the average value of field electromagnetic intensity in suburban electric trains is 20, and in trams and trolleybuses - 30 μT. These figures are even higher on the platforms of metro stations - up to 50-100 µT. Traveling in city subway cars, where the EMF intensity goes off scale beyond 150-200 μT, is pure hell. This exceeds the permissible level of radiation by more than 1000 times! Is it any wonder that people who are forced to use electric vehicles to get around every day are easily fatigued, irritable, and susceptible to various diseases?!

My home is my castle! This phrase, born in England, could be uttered by a person who closed the door behind him. Now this is far from the case! Each more or less electrified box considers it its duty to release into the atmosphere some product that affects our body. All our favorite household appliances - electric stoves, washing machines, vacuum cleaners, kettles, irons, mixers, coffee makers (even electrical wiring and power lines) - create an electromagnetic field. It cannot be seen, heard, smelled, tasted or touched. However, you can study it and protect yourself from its radiation. How dangerous are electromagnetic waves really? And isn't it better to throw your favorite computer out the window?

Many people, unfortunately, are not even aware of the serious danger that operating electrical household appliances pose. Take, for example, a regular kitchen stove. The hostess is usually located near its front panel. The magnitude of the field electromagnetic intensity at the stove (within 20-30 cm) is 1-3 µT. Can you imagine the risk to which housewives who have to prepare food for their families every day expose their health?! The indicators of field electromagnetic intensity generated by electric kettles are unexpectedly small - only 2.6 µT, for irons - about 0.2 µT.

Of course, no one disputes that carriers of electromagnetic radiation provide us with both work and everyday comfort. It is difficult to imagine our life without airplanes, trains and subways, televisions and computers, washing machines, cell phones and much more. But for all these technical conveniences, a person, unfortunately, has to pay with his own health.

So, man, like animals and plants - all living things - is subject to the influence of electromagnetism. It can be both harmful and beneficial. Doctors and scientists have long been exploring the possibilities of weakening the first and strengthening the second. For a better understanding of how EMR acts on the human body, we decided to go to the Railway Clinical Hospital for a consultation with the workshop general practitioner of the first category, Svetlana Yurievna Shiryaeva. Electric train drivers and assistant drivers are assigned to Svetlana Yuryevna’s section. In a conversation with the doctor, we learned a lot of interesting and educational things. It turns out that depending on the intensity and duration of exposure to electromagnetic radiation, acute and chronic forms of damage to the body are distinguished.

Most often, patients complain of general weakness, fatigue, a feeling of weakness, decreased performance, sleep disturbance, irritability, sweating, headache of undetermined localization, dizziness, weakness. Some are bothered by pain in the heart area, sometimes of a compressive nature, radiating to the left arm and shoulder blade, and shortness of breath. Painful phenomena in the heart area are more often felt towards the end of the working day, after nervous or physical stress. Individuals may complain of blurred vision, decreased memory, and inability to concentrate and engage in mental work.

· Unplug non-working appliances to reduce “electromagnetic pollution.” This also applies to a mobile phone. Do not talk for more than 3-4 minutes, use SMS more often, and also carry the device in a case that shields electromagnetic waves. At home it is better to use cable.

· Do not move the bed close to a wall that may contain reinforced concrete structures that have electromagnetic properties. The minimum distance between the wall and the bed should be 10 cm.

· When purchasing another household appliance, remember: the lower the power, the lower the level of its EMF, that is, the harmfulness.

· Buy an air ionizer - it removes the effects of electrostatic fields.

· When you make repairs, replace the usual wiring with shielded wiring and use paints and wallpaper with shielding properties.

· Do not use cell phones for pregnant women, starting from the moment the fact of pregnancy is established and throughout the entire period of pregnancy, and for children.

· For schoolchildren, the duration of continuous computer lessons should not exceed: 1st grade - 10 minutes, 2-5 grades - 15 minutes, 6-7 grades - 20 minutes, 8-9 grades - 25 minutes, 10-11 grades - in the first hour training sessions - 30 minutes, the second - 20 minutes.

Conclusion.

In my work, I tried to show the importance, significance and relevance of studying the influence of electromagnetic radiation on humans, in particular household items, human household items, as well as the need to study this mysterious factor on the functioning of the human body. Humanity has stepped into a new era - the era of high technology and machines. But until we know what other secrets are hidden in phenomena invisible to us, we will not be able to guarantee our safety.

The practical significance of this work lies in the fact that this material can be used in physics lessons, class hours, elective courses in physics, as well as at parent-teacher meetings to raise public awareness.
