The influence of electromagnetic radiation on the human body (abbreviated as EMR, electromagnetic field - EMF) has been studied by specialists since the invention of electricity: large research institutes have conducted research on children, pregnant women and even not whole generations of people.
As a result, according to the official data of the WHO (World Health Organization), EMR is recognized as dangerous if exposed for too long.
Radiation sources These are mobile electronics, telephone towers, transformers and many other electronic devices. It is impossible to protect yourself from electromagnetic radiation. It is contained in a natural amount in the natural field of the earth. For example, the result of EMP in the atmosphere is flashes of ions during the northern lights.
But if the influence of electromagnetic radiation on a person is negative, how to maintain one's health and compensate for unpleasant ailments?
Sources of electromagnetic radiation
The more electronics are produced, the more EMP sources humanity receives. You can not demand to stop the process of technologization: the scientific and technological revolution has led to the rise of electronics.
Now it occupies an important place in human life. Some electrical appliances even support the lives of hospital patients on mechanical ventilation or in a coma, and in these cases, the effect of EMR is negligible.
If radiation sources are to be avoided, the only way out is to simply not buy certain items or go anywhere near the following range of influencing things:
- Cell phones;
- tablets;
- LCD TVs;
- energy-saving lamps;
- transformer boxes;
- large electrical cables;
- sockets;
- refrigerators;
- domestic electrical generators;
- devices for tomography of the brain;
- and much more.
The effect on the human body is the stronger, the longer he uses the device. To limit the action, it is enough to move away from the equipment by a few meters.
Results of various studies
In the USSR, Spain, the USA, Great Britain and other countries, studies were conducted on the subject of the effect of EMR on children and adults. Here are the main facts about radiating devices that were revealed during the experiments.
How does radiation affect the embryo?
Pregnant women who constantly worked at the PC during the period of bearing a child were more prone to miscarriages.
80% had prerequisites for its appearance and even full-fledged cases.
The other study group, who didn't spend as much time around electronics, had a much lower miscarriage rate. The study was conducted in the United States in the early 2000s. Now computer technology has stepped forward, and the waves have become less dangerous for humans.
Children who talked on the phone for 20 minutes then showed changes in brain activity for 2 hours. A group of 11-13 years old was taken for testing. The experiment was set up in Britain in the 90s.
The same experts, but later tested the impact of computers on children and adults. Children about 10 years old showed blood and EEG changes similar to those of cancer patients after only half an hour. Teenagers - in an hour, and adults - in 2 hours. The changes faded away within the same amount of time.
Experts from the University of Bristol have proven that the reaction rate in children aged 11-14 who constantly use the phone decreases by 1.5-2 times. Similar results were revealed by Finnish studies that studied the effects of electromagnetic fields and radiation on the human body.
In the USSR, experiments were carried out on animals. The offspring of those individuals that were even slightly irradiated during pregnancy turned out to be less viable. It showed anomalies not only in development, but also at the genetic level.
Based on the above data, EMR does indeed have an effect on living organisms, including humans.
How exactly does the process of exposure take place, which organs are affected by electromagnetic waves?
The nature of changes under the influence of EMR
Electromagnetic waves- these are some vibrations that transmit energy from induction electrical systems and affect living organisms and inanimate objects.
Induction or irradiation occurs when electrons move unevenly inside a closed space. Electrons are also part of the human body, as a result of which a microscopic magnetic and electronic field arises around a person.
Electromagnetic radiation affects a person by changing his natural field. Some life functions depend on the field. For example, own electromagnetic radiation affects the reaction rate of neurons, brain activity, reaction.
At external influence, leading to violations of the natural levels of the waves, the functions go astray. As a result, the body begins to get sick, showing various EMR-related dysfunctions.
What does radiation affect?
The waves emitted by electrical appliances and natural sources affect most of the departments of the human body:
- reproductive system;
- cardiovascular system;
- endocrine organs;
- departments responsible for immunity;
- nervous system;
- brain.
Each department in its own way suffers from constant doses of radiation. And although the waves are less dangerous than radiation is commonly believed, the problem of EMP is more relevant: the induction of waves surrounds us at every step, and therefore is more dangerous.
Effect of EMR on the brain
Studies by prestigious British and American institutes of science, Finnish organizations and Russian research institutes have shown that EMR reduces activity nervous system.
Signals from the brain to the periphery and to reverse side transmitted more slowly. Part of the information is lost along the way, resulting in failures: convulsions, absent-mindedness, incorrect mechanical movements.
Decreases, especially in children, the reaction rate. This leads to an increased risk of death due to accidents, the suppression of a sports career. Waves have a negative effect on brain activity, temporarily exerting a kind of "stupefying" effect on a person.
Side effects for the reproductive system
With the constant impact of induction on the reproductive system, the reproductive function decreases. A person either becomes completely infertile, or partially loses the viability of germ cells.
Male gametes - spermatozoa - stick together, which makes it more difficult to conceive a child. In women, the menstrual cycle is interrupted.
People with "electrical" professions (repair of transformer booths, electrician, IT specialist) often have children with developmental anomalies.
Depression of the cardiovascular system
Vessels, especially in the eye area, after a long stay in front of radiating devices are significantly narrowed. The outflow and inflow of blood slows down, the brain and other organs suffer from oxygen starvation.
Due to their malnutrition, vision deteriorates sharply, the heart begins to “play pranks”. People who are prone to heart attacks are at greater risk of their occurrence when working with PCs and mobile devices.
Changes in the endocrine system
The thyroid gland has recently been showing dysfunction mainly in adolescents. This is caused not only by natural causes (their rapid growth and hormonal changes), but also by the influence of electronic devices.
With constant exposure to EMR, the risk of developing iodine deficiency, excess thyroxine production, and delayed physical development increases.
Regular computer users show increased rates of ankle swelling, even if the breaks and exercises necessary to compensate for them were taken during work. It is also associated with hormonal disruptions.
Conclusion on the effect of radiation on humans
It cannot be unequivocally said that one should abandon all electronic devices at once and go to healthy lifestyle life. It is impossible to refuse their use. Easier to comply simple recommendations, which will reduce the negative effect of electronics.
Children should use phones and computers as little as possible, about 30-60 minutes a day. Adults should be limited to 2 hours. When working with electronics, you need constant breaks.
Modern science has divided the material world around us into matter and field.
Does matter interact with the field? Or maybe they coexist in parallel and electromagnetic radiation does not affect the environment and living organisms? Let's find out how electromagnetic radiation affects the human body.
Duality of the human body
Life on the planet originated under the influence of an abundant electromagnetic background. For thousands of years, this background has not undergone significant changes. Influence electromagnetic field on the various functions of a wide variety of living organisms was stable. This applies both to its simplest representatives and to the most highly organized beings.
However, as humanity “matureds”, the intensity of this background began to increase continuously due to artificial man-made sources: overhead power transmission lines, household appliances, radio relay and cellular communication lines, and so on. The term "electromagnetic pollution" (smog) was coined. It is understood as the totality of the entire spectrum of electromagnetic radiation that has a negative biological effect on living organisms. What is the mechanism of the impact of electromagnetic fields on a living organism, and what can be the consequences?
In search of an answer, we will have to accept the concept that a person has not only a material body, consisting of an unimaginably complex combination of atoms and molecules, but also has one more component - an electromagnetic field. It is the presence of these two components that ensures the connection of a person with the outside world.
The impact of the electromagnetic web on a person's field affects his thoughts, behavior, physiological functions and even vitality.
A number of modern scientists believe that diseases of various organs and systems occur due to the pathological effects of external electromagnetic fields.
The spectrum of these frequencies is very wide - from gamma radiation to low-frequency electrical oscillations, so the changes they cause can be very diverse. The nature of the consequences is affected not only by the frequency, but also by the intensity, as well as the time of exposure. Some frequencies cause thermal and information impact, others have a destructive effect at the cellular level. In this case, decomposition products can cause poisoning of the body.
The norm of electromagnetic radiation for humans
Electromagnetic radiation turns into a pathogenic factor if its intensity exceeds the maximum permissible norms for a person verified by many statistical data.
For radiation sources with frequencies:
Radio and television equipment, as well as cellular communications, operate in this frequency range. For high voltage transmission lines, the threshold value is 160 kV/m. Exposure to electromagnetic radiation in excess of these values is likely to cause adverse health effects. Real values the voltage of the power line is 5–6 times less than the dangerous value.
radio wave sickness
As a result of clinical studies that began back in the 60s, it was found that under the influence of electromagnetic radiation on a person, changes occur in his body in all critical systems. Therefore, it was proposed to introduce a new medical term - "radio wave disease". According to researchers, its symptoms are already spreading to a third of the population.
Its main manifestations - dizziness, headaches, insomnia, fatigue, deterioration in concentration, depression - do not have much specificity, so the diagnosis of this disease is difficult.
However, in the future, these symptoms develop into serious chronic diseases:
- cardiac arrhythmia;
- fluctuations in blood sugar levels;
- chronic respiratory diseases, etc.
To assess the degree of danger of electromagnetic radiation for humans, consider its effect on different body systems.
The impact of electromagnetic fields and radiation on the human body
The human nervous system is very sensitive to electromagnetic effects. Nerve cells of the brain (neurons) as a result of "intervention" of external fields worsen their conductivity. This can provoke severe and irreversible consequences for the person himself and his environment, since the changes affect the holy of holies - the higher nervous activity. But it is she who is responsible for the entire system of conditioned and unconditioned reflexes. In addition, memory deteriorates, the coordination of brain activity with the work of all parts of the body is disrupted. Mental disorders are also very likely, up to crazy ideas, hallucinations and suicide attempts. Violation of the adaptive capacity of the body is fraught with exacerbation of chronic diseases.- The reaction of the immune system to the effects of electromagnetic waves is very negative. There is not only suppression of immunity, but also an attack of the immune system on its own body. Such aggression is explained by a drop in the number of lymphocytes, which should ensure victory over the infection invading the body. These "valiant warriors" also fall victim to electromagnetic radiation.
- In the state of human health, the quality of blood plays a paramount role. What is the effect of electromagnetic radiation on the blood? All elements of this life-giving fluid have certain electrical potentials and charges. Electrical and magnetic components that form electromagnetic waves can cause destruction or, conversely, adhesion of erythrocytes, platelets, and cause obstruction of cell membranes. And their action on the hematopoietic organs causes disturbances in the work of the entire hematopoietic system. The reaction of the body to such a pathology is the release of excessive doses of adrenaline. All these processes have a very negative effect on the work of the heart muscle, blood pressure, myocardial conduction and can cause arrhythmia. The conclusion is not comforting - electromagnetic radiation has an extremely negative effect on the cardiovascular system.
- The impact of an electromagnetic field on the endocrine system leads to stimulation of the most important endocrine glands - the pituitary gland, adrenal glands, thyroid gland, etc. This causes disruptions in the production of the most important hormones.
One of the consequences of disorders in the nervous and endocrine systems are negative changes in the genital area. If we evaluate the degree of influence of electromagnetic radiation on male and female sexual function, then the sensitivity of the reproductive system of women is much higher to electromagnetic effects than that of men. This is also associated with the danger of influencing pregnant women. Pathologies of the development of the child at different stages of pregnancy can manifest themselves in a decrease in the rate of fetal development, defects in the formation of various organs, and even lead to premature birth. The first weeks and months of pregnancy are especially vulnerable. The fetus is still loosely attached to the placenta, and the electromagnetic "shock" can interrupt its connection with the mother's body. In the first three months, the most important organs and systems of the growing fetus are formed. And the misinformation that external electromagnetic fields can bring can distort the material carrier of the genetic code - DNA.
How to reduce the negative impact of electromagnetic radiation
The listed symptomatology testifies to the strongest biological influence of electromagnetic radiation on human health. The danger is aggravated by the fact that we do not feel the effects of these fields and the negative effect accumulates over time.
How to protect yourself and your loved ones from electromagnetic fields and radiation? The implementation of the following recommendations will minimize the consequences of the operation of electronic household appliances.
Our everyday life includes more and more diverse technology, facilitating and decorating our lives. But the effect of electromagnetic radiation on humans is not a myth. Microwave ovens, electric grills, cell phones and some models of electric shavers are champions in terms of the degree of influence on a person. It is almost impossible to refuse these blessings of civilization, but one should always remember the reasonable exploitation of all the technology around us.
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, have a significant impact on us. magnetic storms etc. (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.
Most dangerous property such impacts is that they accumulate over time in the body. As they say: "a drop of water wears away a stone." People who, by occupation, use a lot of various equipment- computers, telephones - a decrease in immunity, frequent stress, a decrease in sexual activity, 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, one way or another exposed to mobile and WiFi 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. 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. Influence of high-intensity EMF on immune system organism manifests itself 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 the impact of various environmental factors is the hypothalamus-pituitary-adrenal cortex system.
Effect of electromagnetic radiation on the cardiovascular system:
It can also be noted that violations cardiovascular systems s. It manifests itself in the form of pulse lability and blood pressure. Phase changes in the composition of peripheral blood are noted.
The influence of electromagnetic radiation on the reproductive system:
- 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.
- 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.
- 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 adults, 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 the electromagnetic field, and active human growth occurs from the moment of conception to about 16 years.
Pregnant women also fall into this risk group, since EMF is biologically active in relation to embryos. When talking to a pregnant woman 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:
At the Neurodiagnostic scientific institute in Spain in 2001 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 persists for another two hours after they hang up.
The University of Bristol in the UK ended 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, dysfunctions 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.

The rapid development of science and technology in the XX century. led to the creation of electromagnetic field generators, which are widely used in industry, communications, the military, radio navigation, healthcare, and everyday life. Their widespread use is accompanied by progressive electromagnetic pollution. environment posing a threat to public health. Indeed, everyone knows about the dangers of many hours of watching television programs and continuous work at the computer during the working day.
Electromagnetic fields are biologically active - living beings react to their action. However, a person does not have a special sense organ for determining electromagnetic fields (with the exception of the optical range). The most sensitive to electromagnetic fields are the central nervous system, cardiovascular, and reproductive systems.
Long-term human exposure industrial frequency(50 Hz) leads to disorders that are subjectively expressed by complaints of headache in the temporal and occipital region, lethargy, sleep disturbance, memory loss, irritability, apathy, heart pain, heart rhythm disturbance. There may be functional disorders in the central nervous system, as well as changes in the composition of the blood.
Impact electrostatic field on a person is associated with the flow of a weak current through it. In this case, electrical injuries are never observed. However, due to a reflex reaction to the flowing current, mechanical injury from a blow against adjacent structural elements, a fall from a height, etc. is possible. The central nervous system and the cardiovascular system are most sensitive to electrostatic fields. People working in the area of electrostatic fields complain of irritability, headache, sleep disturbance.
When exposed magnetic fields there may be violations of the functions of the nervous, cardiovascular and respiratory systems, the digestive tract, changes in the composition of the blood. With the local action of magnetic fields (primarily on the hands), there is a feeling of itching, pallor and cyanosis of the skin, swelling and induration, and sometimes keratinization of the skin.
Impact radio frequency range is determined by the energy flux density, radiation frequency, exposure duration, irradiation mode (continuous, intermittent, pulsed), the size of the irradiated body surface, individual characteristics of the organism. The impact of electromagnetic radiation can manifest itself in various forms - from minor changes in some body systems to serious disturbances in the body. The absorption of the energy of electromagnetic radiation by the human body causes a thermal effect. Starting from a certain limit, the human body cannot cope with the removal of heat from individual organs, and their temperature may rise. In this regard, exposure to electromagnetic radiation is especially harmful to tissues and organs with insufficiently intense blood circulation (eyes, brain, kidneys, stomach, bile and bladder). Irradiation of the eyes can lead to burns of the cornea, and exposure to EMR in the microwave range can lead to clouding of the lens - cataracts.
With prolonged exposure to electromagnetic radiation of the radio frequency range, even of moderate intensity, disorders of the nervous system, metabolic processes, and changes in blood composition can occur. Hair loss and brittle nails may also be observed. At an early stage, the violations are reversible, but in the future there are irreversible changes in the state of health, a persistent decrease in working capacity and vitality.
Infrared (thermal) radiation, being absorbed by tissues, causes a thermal effect. The most affected by infrared radiation are the skin and organs of vision. In case of acute skin damage, burns, a sharp expansion of capillaries, and increased skin pigmentation are possible. With chronic irradiation, a persistent change in pigmentation appears, a red complexion, for example, in glassblowers, steelworkers. An increase in body temperature worsens the state of health, reduces the performance of a person.
light emission at high energies, it also poses a danger to the skin and eyes. Pulsations of bright light impair vision, reduce performance, affect the nervous system (light radiation is discussed in more detail in Chapter 2, Section V).
Ultraviolet radiation (UVR) high levels can cause eye burns up to temporary or complete loss of vision, acute inflammation of the skin with redness, sometimes swelling and blistering, while fever, chills, and headache are possible. Acute eye lesions are called electrophthalmia. Chronic UVR of a moderate level causes a change in skin pigmentation (tanning), causes chronic conjunctivitis, inflammation of the eyelids, clouding of the lens. Prolonged exposure to radiation leads to skin aging and the development of skin cancer. Small levels of UV radiation are useful and even necessary for humans. But in industrial conditions, UV radiation is usually a harmful factor.
Impact laser radiation (LI) per person depends on the intensity of radiation (energy of the laser beam), wavelength (infrared, visible or ultraviolet range), the nature of their radiation (continuous or pulsed), exposure time. On fig. 1 shows the factors that determine the biological effect of laser radiation. Laser radiation acts selectively on various organs, highlights local and general damage to the body.
Rice. 1. Factors determining the biological effect of laser radiation
When the eyes are irradiated, the cornea and lens are easily damaged and lose their transparency. The heating of the lens leads to the formation of cataracts. The most dangerous for the eyes is the visible range of laser radiation, for which the optical system of the eye becomes transparent and the retina is affected. Damage to the retina of the eye can lead to temporary loss of vision, and at high energies of the laser beam even to the destruction of the retina with loss of vision.
Laser radiation causes damage to the skin of various degrees - from redness to charring and the formation of deep skin defects, especially in pigmented areas (birthmarks, places with a strong tan).
Lee, especially in the infrared range, is able to penetrate tissues to a considerable depth, affecting internal organs. For example, direct irradiation of the surface of the abdominal wall causes damage to the liver, intestines and other organs, while irradiation of the head may cause intracranial hemorrhages.
Prolonged exposure to laser radiation of even low intensity can lead to various functional disorders of the nervous, cardiovascular systems, endocrine glands, blood pressure, increased fatigue, and decreased performance.
Pathological changes caused by artificial electromagnetic fields in a living organism
The severity of the identified disorders is directly dependent on the strength of the electromagnetic field, the duration of its exposure, the combination of certain levels of exposure and exposure time, the physical characteristics of various ranges of the electromagnetic field, environmental conditions, and the functional state of the body.
Most researchers who have studied the clinical picture of diseases that have arisen under the influence of electromagnetic fields agree that the nervous system reacts to electromagnetic waves earlier than others. Examination of a large number of patients made it possible to identify a symptom complex characteristic of the so-called magnetic or radio wave disease. At the same time, the changes occurring in the body can be characterized as a functional disorder of the central nervous system, occurring mainly as an autonomic dysfunction with asthenic phenomena, less often as a neurasthenic type.
Systematization of the clinical manifestations of the disease made it possible to identify its three main forms: asthenic syndrome, vegetative-vascular (neurocirculatory) dystonia and diencephalic (microdiencephalic) syndrome.
At asthenic syndrome possible various violations of autonomic functions, lability of the pulse and blood pressure. The changes are usually reversible and treatable.
At the core vegetative-vascular dystonia vascular lability lies: fluctuations in heart rate and blood pressure, bradycardia, followed by tachycardia, arterial hypotension, sometimes hypertension, changes in the function of the heart and capillaries. The disease may be chronic.
For diencephalic syndrome complex visceral dysfunctions, vegetative-vascular crises occurring against the background of an asthenic state are characteristic. Hypokinesia, hypothalamic-pituitary-adrenal weakness, inhibition of sexual and food reflexes are observed. Changes are not always reversible, such patients need specialized inpatient treatment.
According to the severity of the course of the disease, the following degrees are distinguished: the first, or initial (compensated), the second (moderately expressed), the third (expressed). In some cases, the disease becomes chronic. Children are especially affected by radio wave disease.
Each apartment is fraught with danger. We do not even suspect that we live in an environment of electromagnetic fields (EMF), which a person cannot see or feel, but this does not mean that they do not exist.
From the very beginning of life on our planet, there has been a stable electromagnetic background (EMF). For a long time it was practically unchanged. But, with the development of mankind, the intensity of this background began to grow at an incredible speed. Power lines, an increasing number of electrical appliances, cellular communications - all these innovations have become sources of "electromagnetic pollution". How does the electromagnetic field affect the human body, and what are the consequences of this impact?
What is electromagnetic radiation?
In addition to the natural EMF created by electromagnetic waves (EMW) of various frequencies that come to us from space, there is another radiation - domestic, which occurs during the operation of a motley electrical equipment that is available in every apartment or office. Each household appliance, take at least an ordinary hair dryer, passes through itself during operation. electricity, forming an electromagnetic field around. Electromagnetic radiation (EMR) is the force that manifests itself when a current passes through any electrical device, affecting everything that is around him, including a person, who is also a source of electromagnetic radiation. The greater the current passing through the device, the more powerful the radiation.
Most often, a person does not experience a noticeable effect of EMR, but this does not mean that it does not affect us. EMW pass through objects imperceptibly, but sometimes, the most sensitive people feel some kind of tingling or tingling.
We all react differently to EMR. The organism of some can neutralize its impact, but there are individuals who are most susceptible to this influence, which can cause various pathologies in them. Long-term exposure to electromagnetic radiation is especially dangerous for humans. For example, if his house is located near a high-voltage transmission line.
Depending on the wavelength, EMP can be divided into:
- visible light is the radiation that a person is able to perceive visually. The wavelength of light varies from 380 to 780 nm (nanometers), that is, the wavelengths of visible light are very short;
- infrared radiation is in the electromagnetic spectrum between light radiation and radio waves. The length of infrared waves is longer than light and is in the range of 780 nm - 1 mm;
- radio waves. They are also microwaves that emit a microwave oven. These are the longest waves. These include all electromagnetic radiation with wavelengths of half a millimeter or more;
- ultraviolet radiation, which is harmful to most living beings. The length of such waves is 10-400 nm, and they are located in the range between visible and X-ray radiation;
- X-ray radiation is emitted by electrons and has a wide range of wavelengths - from 8 10 - 6 to 10 - 12 cm. This radiation is known to everyone from medical devices;
- gamma radiation is the shortest wavelength (the wavelength is less than 2 10 −10 m), and has the highest radiation energy. This type of EMR is the most dangerous for humans.
The picture below shows the entire spectrum of electromagnetic radiation.
Radiation sources
There are many EMP sources around us that emit electromagnetic waves into space that are not safe for the human body. It is impossible to list all of them.
I would like to focus on more global ones, such as:
- high-voltage power lines with high voltage, and a powerful level of radiation. And if residential buildings are located closer than 1000 meters to these lines, then the risk of oncology among residents of such buildings increases;
- electric transport - electric trains and subway trains, trams and trolleybuses, as well as ordinary elevators;
- radio and television towers, the radiation of which is also particularly dangerous for human health, especially those installed in violation of sanitary standards;
- functional transmitters - radars, locators that create EMP at a distance of up to 1000 meters, therefore, airports and meteorological stations try to place as far as possible from the residential sector.
And on simple ones:
- household appliances, such as a microwave oven, computer, TV, hair dryer, chargers, energy-saving lamps, etc., which are available in every home and are an integral part of our life;
- mobile phones, around which an electromagnetic field is formed that affects the human head;
- electrical wiring and sockets;
- medical devices - X-ray, computed tomography, etc., which we encounter when visiting medical institutions that have the strongest radiation.
Some of these sources have a powerful effect on a person, some - not so much. Anyway, we both used and will continue to use these devices. It is important to be extremely careful when using them and be able to protect yourself from negative impacts in order to minimize the harm they cause.
Examples of sources of electromagnetic radiation are shown in the figure.
The impact of EMR on humans
It is believed that electromagnetic radiation has a negative impact on both human health and behavior, vitality, physiological functions and even thoughts. The person himself is also a source of such radiation, and if other, more intense sources begin to act on our electromagnetic field, then in human body complete chaos can occur, which will lead to various diseases.
Scientists have established that it is not the waves themselves that are harmful, but their torsion (information) component, which is present in any electromagnetic radiation, that is, it is torsion fields that have the wrong effect on health, transmitting negative information to a person.
The danger of radiation lies in the fact that it can accumulate in the human body, and if you use, for example, a computer, mobile phone, etc. for a long time, you may experience headache, fatigue, constant stress, decreased immunity, and the likelihood of diseases of the nervous system and brain. Even weak fields, especially those that coincide in frequency with human EMP, can harm health by distorting our own radiation, and thereby causing various diseases.
A huge impact on human health is played by such factors of electromagnetic radiation as:
- source power and nature of radiation;
- its intensity;
- duration of exposure.
It is also worth noting that exposure to radiation can be general or local. That is, if you take a mobile phone, it affects only a separate human organ - the brain, and the whole body is irradiated from the radar.
What kind of radiation arises from certain household appliances, and their range, can be seen from the figure.
Looking at this table, you can understand for yourself that the farther the source of radiation is from a person, the less its harmful effect on the body. If the hair dryer is in close proximity to the head, and its impact causes significant harm to a person, then the refrigerator has practically no effect on our health.
How to protect yourself from electromagnetic radiation
The danger of EMR lies in the fact that a person does not feel its influence on himself, but it exists and greatly harms our health. If there is special protective equipment in the workplace, then things are much worse at home.
But it is still possible to protect yourself and your loved ones from the harmful effects of household appliances if you follow simple recommendations:
- purchase a dosimeter that determines the intensity of radiation and measure the background from various household appliances;
- do not turn on several electrical appliances at once;
- keep away from them, if possible, at a distance;
- arrange devices so that they are as far away as possible from places of long-term human stay, for example, dining table or recreation areas;
- in children's rooms there should be as few sources of radiation as possible;
- no need to group electrical appliances in one place;
- mobile phone should not be brought closer to the ear than 2.5 cm;
- keep the telephone base away from the bedroom or desktop:
- not be located close to the TV or computer monitor;
- turn off appliances you don't need. If you are not currently using a computer or TV, you do not need to keep them turned on;
- try to reduce the time of using the device, do not be near it constantly.
Modern technology has firmly entered our everyday life. We can't imagine life without mobile phone or computer, and microwave oven, which many have not only at home, but also in the workplace. It is unlikely that anyone will want to refuse them, but it is in our power to use them wisely.
