ELECTROMAGNETIC RADIATION AND ELECTROMAGNETIC FIELDS - INVISIBLE KILLERS

We were taught at school that labor turned a monkey into a man, and scientific and technological progress is the engine of all humanity. It would seem that with its movement the quality and number of years lived by a person should improve. In fact, the deeper STP enters our lives, the harder our lives are and the more often people encounter previously unknown diseases, which appear and develop in direct progression along with technical progress. Let us not dispute that the benefits of civilization are bad. Let's talk about the hidden threat to humans and their descendants - electromagnetic radiation.

Research by scientists over the past decades shows that electromagnetic radiation is no less dangerous than atomic radiation. Electromagnetic smog, interacting with the electromagnetic field of the body, partially suppresses it, distorting the human body’s own field. This leads to a decrease in immunity, disruption of information and cellular exchange within the body, and the occurrence of various diseases. It has been proven that even at a relatively weak level, prolonged exposure to electromagnetic radiation can cause cancer, memory loss, Alzheimer's and Parkinson's diseases, impotence, destruction of the lens of the eye, and a decrease in the number of red blood cells. Electromagnetic fields are especially dangerous for pregnant women and children. Electromagnetic radiation contributes to sexual dysfunction in men and reproductive dysfunction in women.

American and Swedish scientists established a safe limit for human health on the intensity of electromagnetic fields - (0.2 µT). For example, a washing machine - 1 μT, a microwave oven (at a distance of 30 cm) - 8 μT, a vacuum cleaner - 100 μT, and when a train departs for the subway - 50-100 μT.

Scientists have long been talking about the negative impact of electromagnetic fields (EMF) on children’s bodies. Since the size of a child’s head is smaller than that of an adult, the radiation penetrates deeper into those parts of the brain that, as a rule, are not irradiated in an adult. This applies to mobile phones, which simply expose the brain to “local” overheating. Experiments on animals confirmed that with increasing doses of high-frequency radiation, literally welded areas formed in their brains. Research by US scientists has proven that the signal from the phone penetrates the brain to a depth of 37.5 mm, which creates interference in the functioning of the nervous system.

Growing and developing tissues are most susceptible to the adverse effects of the electromagnetic field. It is also biologically active in embryos. A pregnant woman working at a computer is exposed to almost the entire body, including the developing fetus, by EMF. By the way, those who think that laptop computers are practically safe are mistaken. Think carefully about the negative consequences of their exposure before placing a laptop computer on your stomach or lap. Yes, liquid crystal screens do not have an electrostatic field and do not carry x-rays, but a cathode ray tube is not the only source of electromagnetic radiation. Fields can be generated by a supply voltage converter, control circuits and information generation on discrete liquid crystal screens, and other equipment elements.

SO HARMFUL OR NOT?

When talking about EMFs, we can’t help but mention Wi-Fi. On the Internet you can find many articles on this subject: “Wi-Fi networks are dangerous to health”, “Does Wi-Fi have a harmful effect on the human body?”, “Radiation from Wi-Fi networks harms trees, scientists say”, “Is it harmful Wi-Fi technology for children?

In the United States, there are examples of parents suing over Wi-Fi installed in schools and universities. Parents' fears that wireless networks cause irreparable harm to the health of children and adolescents, having a destructive effect on the growing body, are not unfounded. Wi-Fi, for example, operates at the same frequency as a microwave oven. For humans, this frequency is not at all as harmless as it seems. About 20,000 studies have been published recently. They prove the fact that Wi-Fi negatively affects the health of mammals, in particular, human health. Migraines, colds, joint pain, but most often, diseases caused by Wi-Fi include cancer, heart failure, dementia and memory impairment. In the US, UK and Germany, Wi-Fi is increasingly being abandoned in schools, hospitals and universities. The reason for the refusal is said to be harm to human health. Today, there is no official verdict in the case of Wi-Fi, as there was with the WHO recognition of the harm of mobile phones. After all, the revealed truth will bring considerable losses to those who are not interested in it. As they say: “Saving a drowning man is the work of the drowning man himself.” And the reader is right who, after reading an article about the dangers of Wi-Fi, wrote: “In the end, everyone decides for themselves why they are sick.”

ELIMINATE THE NEGATIVE ELECTROMAGNETIC INFLUENCE OF WI-FI

The impact of Wi-Fi on the human body, unlike a mobile phone, is not so noticeable. But if you still use wireless technologies to connect to the Internet or corporate network on an ongoing basis, give them up. Better get yourself a regular twisted pair cable. Try to reduce the time you use wireless networks of any kind. Do not keep the source of electromagnetic radiation close to your body. Minimize the amount of time you use your mobile phone or Bluetooth headset. Use a wired connection. If you are pregnant, try to stay as far away from wireless networks as possible. No one has yet proven the harm of exposure to Wi-Fi on pregnant women. But who knows how this know-how will affect the body of the unborn baby? After all, true love for a child does not lie in buying another toy or beautiful clothes, but in raising a child strong and healthy.

At the Paracelsus Medical Center you can undergo diagnostics of the effects of electromagnetic influences on your body. At the same time, the equipment allows you to differentiate the types of electromagnetic influences - man-made, geopathogenic, radioactive, determine the degree of electromagnetic load (4 degrees in total) and effectively neutralize this negative effect on the body.

In recent years, due to the development of technology, the human body has been exposed to a high level of exposure to electromagnetic radiation (EMR), which could not but cause serious concern throughout the world.

What is the effect on living organisms? Their consequences depend on which category of radiation - ionizing or not - they belong to. The first type has a high energy potential, which acts on atoms in cells and leads to a change in their natural state. It can be deadly as it causes cancer and other diseases. Non-ionizing radiation includes electromagnetic radiation in the form of radio waves, microwave radiation and electrical vibrations. Although it cannot change the structure of the atom, its impact can lead to irreversible consequences.

Invisible danger

Publications in the scientific literature have raised the issue of the adverse effects on individuals and society as a whole of non-ionizing EMF radiation emanating from power, electrical and wireless devices in the home, at work, in educational and public institutions. Despite numerous challenges in establishing conclusive scientific evidence of harm and gaps in understanding the precise mechanisms of harm, epidemiological analysis increasingly suggests a significant potential for injury from non-ionizing radiation exposure. Protection against electromagnetic radiation is becoming increasingly important.

Because medical education does not emphasize environmental health, some physicians are not fully aware of the potential health problems associated with EMR and, as a result, non-ionizing radiation events may be misdiagnosed and treated ineffectively.

While the possibility of damage to tissues and cells associated with exposure to X-ray radiation is beyond doubt, the influence of electromagnetic radiation on living organisms, when it comes from power lines, mobile phones, electrical appliances and some machines, has only recently begun to attract attention as a potential threat. health.

Electromagnetic spectrum

Refers to a type of energy that emanates or radiates far beyond its source. Electromagnetic radiation energy exists in various forms, each of which has different physical properties. They can be measured and expressed using frequency or wavelength. Some waves have a high frequency, others have a medium frequency, and others have a low frequency. The range of electromagnetic radiation includes many different forms of energy coming from different sources. Their name is used to classify types of EMR.

The short wavelength of electromagnetic radiation, corresponding to high frequency, is a characteristic of gamma rays, x-rays and ultraviolet radiation. More spectrum includes microwave radiation and radio waves. Light radiation belongs to the middle part of the EMR spectrum; it provides normal vision and is the light that we perceive. Infrared energy is responsible for human perception of heat.

Most forms of energy, such as X-rays, ultraviolet and radio waves, are invisible and undetectable to humans. Their detection requires measuring electromagnetic radiation using special instruments, and, as a result, people cannot assess the extent of exposure to energy fields in these ranges.

Despite the lack of perception, exposure to high-frequency energy, including X-rays, called ionizing radiation, is potentially harmful to human cells. By changing the atomic composition of cellular structures, breaking chemical bonds and inducing the formation of free radicals, sufficient exposure to ionizing radiation can damage the genetic code in DNA or provoke mutations, thereby increasing the risk of malignancy or cell death.

Anthropogenic EMP

The effect of electromagnetic radiation on the body, especially non-ionizing radiation, which refers to forms of energy with lower frequencies, has been underestimated by many scientists. It was not believed to produce adverse effects at normal exposure levels. Recently, however, growing evidence suggests that some frequencies of non-ionizing radiation may potentially cause biological harm. Most studies of their health effects have focused on the following three main types of anthropogenic EMR:

• lower scale of electromagnetic radiation from power lines, electrical appliances and electronic equipment;
• microwave and radio emissions from wireless communications devices such as cell phones, cell towers, antennas, and television and radio towers;
• electrical pollution due to the operation of certain types of equipment (for example, plasma TVs, some energy-saving appliances, variable speed motors, etc.) that produce signals whose frequency of electromagnetic radiation is in the range of 3-150 kHz (propagated and re-radiated by wiring).

Currents in the ground, which are sometimes called stray currents, are not limited by wires. Current follows the path of least resistance and can pass through any available paths, including the ground, wires, and various objects. Accordingly, electrical voltage is also transmitted through the ground and through building structures through metal water or sewer pipes, resulting in non-ionizing radiation being released into the immediate environment.

EMR and human health

While studies examining the negative effects of electromagnetic radiation have sometimes produced conflicting results, findings of reproductive dysfunction and cancer susceptibility appear to support suspicions that EMF exposure may pose a threat to human health. Adverse pregnancy outcomes, including miscarriages, stillbirths, preterm births, altered sex ratios, and congenital anomalies have all been associated with maternal exposure to EMR.

A large prospective study published in the journal Epidemiology, for example, reported peak EMR exposure in 1,063 pregnant women in the San Francisco area. Participants in the experiment wore magnetic field detectors, and the scientists found a significant increase in fetal mortality as the level of maximum EMF exposure increased.

EMR and cancer

Claims that intense exposure to certain EMR frequencies may be carcinogenic have been studied. For example, the International Journal of Cancer recently published an important case-control study on the association between childhood leukemia and magnetic fields in Japan. By assessing levels of electromagnetic radiation in bedrooms, scientists confirmed that high levels of exposure lead to a significantly greater risk of childhood leukemia.

Physical and psychological impact

People with electromagnetic hypersensitivity often suffer from exhaustion, which can affect any part of the body, including the central nervous system, musculoskeletal system, gastrointestinal tract and endocrine system. These symptoms often lead to constant psychological stress and fear of being affected by EMP. Many patients become incapacitated by the mere thought that an invisible wireless signal at any time and anywhere can provoke painful sensations in their body. Constant fear and concern about health problems affect well-being up to the development of phobia and fear of electricity, which in some people makes them want to leave civilization.

Mobile phones and telecommunications

Cell phones transmit and receive signals using EMFs, which are partially absorbed by their users. Since these sources of electromagnetic radiation are usually in close proximity to the head, this feature has led to concerns about the possible adverse effects of their use on human health.

One problem in extrapolating results from their use in experimental rodent studies is that the frequency of maximum absorption of RF energy depends on body size, shape, orientation and position.

Resonant absorption in rats is in the range of microwaves and operating frequencies of mobile phones used in experiments (from 0.5 to 3 GHz), but on the scale of the human body it occurs at 100 MHz. This factor can be taken into account when calculating absorbed dose rate, but poses a problem for those studies in which only the external field strength is used to determine the level of exposure.

The relative depth of penetration in laboratory animals compared to the size of the human head is greater, and the tissue parameters and the mechanism of heat redistribution differ. Another potential source of inaccuracy in exposure levels is the effect of radiofrequency radiation on the cell.

The effect of high-voltage radiation on people and the environment

Power lines with voltages above 100 kV are the most powerful sources of electromagnetic radiation. Research into radiation effects on technical personnel began with the start of construction of the first 220 kV power lines, when cases of deteriorating health of workers appeared. The commissioning of 400 kV power lines led to the publication of numerous works in this area, which subsequently became the basis for the adoption of the first regulations limiting the effect of the 50-Hz electric field.

Power lines with a voltage of more than 500 kV have an impact on the environment in the form of:

• electric field with a frequency of 50 Hz;
• radiation;
• magnetic field of industrial frequency.

EMF and the nervous system

The mammalian blood-brain barrier consists of endothelial cells associated with the zona septa, as well as adjacent pericytes and extracellular matrix. Helps maintain a highly stable extracellular environment necessary for accurate synaptic transmission and protects neural tissue from damage. Increasing its low permeability to hydrophilic and charged molecules can be harmful to health.

Ambient temperatures that exceed the limits of mammalian thermoregulation increase the permeability of the blood-brain barrier to macromolecules. Neuronal uptake of albumin in various areas of the brain depends on its temperature and appears when it increases by 1 °C or higher. Since sufficiently strong radiofrequency fields can lead to tissue heating, it is logical to assume that the influence of electromagnetic radiation on humans results in increased permeability of the blood-brain barrier.

EMF and sleep

The upper scale of electromagnetic radiation has some effect on sleep. This topic has become relevant for several reasons. Among other symptoms, complaints of sleep disturbances have been mentioned in anecdotal reports of people believing that they are being affected by EMR. This has led to speculation that electromagnetic fields may interfere with normal sleep patterns, with attendant health consequences. The potential risk of sleep disturbance must be considered in the light of the fact that it is a very complex biological process controlled by the central nervous system. Although the exact neurobiological mechanisms have not yet been established, regular alternation between waking and resting states is a necessary requirement for proper brain function, metabolic homeostasis and the immune system.

In addition, sleep appears to be precisely the physiological system whose study will make it possible to clarify the influence of high-frequency electromagnetic radiation on humans, since in this biological state the body reacts sensitively to external stimuli. There is evidence that weak EMFs, the intensity of which is well below that which would cause a rise in temperature, can also cause biological effects.

Currently, research into the effects of non-ionizing high-frequency EMR is clearly focused on the risk of cancer, due to concerns about the carcinogenic properties of ionizing radiation.

Negative manifestations

Thus, the influence of electromagnetic radiation on humans, even non-ionizing ones, occurs, especially in the case of high-voltage power lines and the corona effect. Microwave radiation affects the nervous, cardiovascular, immune and reproductive systems, including causing damage to the nervous system, changing its reaction, electroencephalogram, blood-brain barrier, causing disturbances (wakefulness - sleep) by interfering with the functioning of the pineal gland and creating hormonal imbalance , changes in heart rate and blood pressure, impairing immunity to pathogens, causing weakness, exhaustion, growth problems, DNA damage and cancer.

It is recommended to construct buildings away from EMI sources, and protection from electromagnetic radiation of high-voltage power lines must be mandatory. In cities, cables must be laid underground, and equipment that neutralizes the effects of EMR must be used.

Based on the results of a correlation analysis based on experimental data, it was concluded that the impact of electromagnetic radiation from power lines on humans can be significantly reduced by reducing the distance of wire sag, which will lead to an increase in the distance between the conductive line and the measurement point. In addition, this distance is also influenced by the terrain under the power line.

Precautions

Electricity is an integral part of life in modern society. This means that EMP will always be around us. And in order for EMFs to make our lives easier, not shorter, we should take some precautions:

• Children should not be allowed to play near power lines, transformers, satellite transmitters, or microwave sources.
• Places where the density exceeds 1 mG should be avoided. It is necessary to measure the EMF level of devices in the off and on state.
• It is necessary to rearrange the office or home in such a way as not to be exposed to the field of electrical appliances and computers.
• You should not sit too close in front of the computer. Monitors vary greatly in the strength of their EMR. Do not stand near a running microwave oven.
• Move electrical appliances at least 2 m from the bed. Wiring should not be allowed under the bed. Remove dimmers and 3-way switches.
• Precautions should be taken when using cordless devices such as electric toothbrushes and razors.
• It is also recommended to wear as little jewelry as possible and remove it at night.
• It is also necessary to remember that EMR passes through walls, and take into account sources in the next room or behind the walls of the room.

Conclusion

All substances continuously emit electromagnetic waves. The radiation spectrum covers a wide range of wavelengths: from radio waves with a length of hundreds of meters to hard cosmic radiation with a wavelength of 10-12 m. The natural electromagnetic spectrum covers wavelengths from 0.00000000000001 meters to 100,000 kilometers. Thermal (infrared) radiation is emitted by bodies in a certain temperature range. The higher the body temperature, the shorter the wavelength and the higher the intensity of the radiation.

An infrared heater is ideal wherever local surface heating is needed. Being completely harmless, infrared heaters provide effective heating.

In the process of life, a person is constantly in the zone of action of the electromagnetic (EM) field of the Earth. This field, called background, is considered normal and does not cause any harm to human health.

The various “smart” machines that have become such a part of our lives (computers, cell phones, microwave ovens, televisions) can actually do a lot more harm to a person than it seems at first glance.

Extensive research on the impact of electromagnetic radiation on human health in the world began back in the 60s of the last century. A large amount of clinical material has been accumulated on the adverse effects of magnetic and electromagnetic fields. Already at this time, it was proposed to introduce new diseases “Radio wave disease” or “Chronic damage by microwaves.” Subsequently, the work of scientists in Russia established that the human nervous system is the most sensitive to the effects of electromagnetic fields. The results of the work carried out were used in the development of sanitary regulatory documents in Russia.

Therefore, consideration of the influence of electromagnetic radiation on the human body is relevant .

Target our abstract: learn about the mechanism and consequences of exposure to electromagnetic radiation.

We set ourselves the following tasks :

analyze the literature on this issue;

identify the mechanism of radiation influence

describe the consequences of this impact.

Object of study is electromagnetic radiation.

The abstract was completed on the basis of Municipal Educational Institution with in-depth study of the English language No. 120 in Samara.

Fig.1 Electromagnetic wave range

Electromagnetic field (EMF) is a physical field of moving electric charges in which interaction occurs between them. Particular manifestations of EMF are electric and magnetic fields. Since changing electric and magnetic fields generate magnetic and electric fields, respectively, at neighboring points in space, these two interconnected fields propagate in the form of a single EMF. EMFs are characterized by oscillation frequency f (or period T = 1/f), amplitude E (or H) and phase

, which determines the state of the wave process at each moment of time. Oscillation frequency is expressed in hertz (Hz), kilohertz (1 kHz = 10 3 Hz), megahertz (1 MHz = 10 6 Hz) and gigahertz (1x 10 9 Hz). The phase is expressed in degrees or relative units, multiples of . Oscillations of the electric (E) and magnetic (H) fields, which make up a single EMF, propagate in the form of electromagnetic waves, the main parameters of which are wavelength (), frequency (f) and propagation speed. Wave formation occurs in the wave zone at a greater distance from the source. In this zone the waves change in phase. At shorter distances - in the induction zone - E - the waves change out of phase and quickly decrease with distance from the source. In the induction zone, energy alternates between an electric and a magnetic field. E and H are assessed separately. In the wave zone, radiation is assessed in terms of power flux density - watts per square centimeter. In the electromagnetic spectrum, EMFs occupy the radio frequency range (frequency from 3x104 to 3x1012 Hz) and are divided into several types (Fig. 1). In extreme conditions, in particular during space flight, radio and television equipment becomes a source of EMF of various characteristics. The biological effect of EMF on a living organism is based on the absorption of energy by tissues. Its value is determined by the properties of the irradiated tissue or its biophysical parameters - dielectric constant () and conductivity. Due to the high water content in them, body tissues should be considered as dielectrics with losses. The depth of penetration of EMF into tissues is greater, the lower the absorption. During total body irradiation, energy penetrates to a depth of 0.001 wavelengths. Depending on the intensity of exposure and exposure, wavelength and the initial functional state of the body, EMFs cause changes in the tissues under study with or without an increase in their temperature.

Power lines and strong radio transmitting devices create an electromagnetic field that is several times higher than the permissible level. To protect humans, special sanitary standards have been developed (GOST 12.1.006-84 regulates the impact of electromagnetic radiation on humans), including those that prohibit the construction of residential and other facilities near strong sources of radiation.

Often more dangerous are sources of weak electromagnetic radiation that operate over a long period of time. Such sources mainly include audio-video equipment and household appliances. The most significant influence on humans is exerted by mobile phones, microwave ovens, computers and televisions.

Telephones and microwave ovens operate mainly for a short time (on average from 1 to 7 minutes), televisions do not cause significant harm, because usually located at a distance from spectators. The problem of electromagnetic radiation emanating from personal computers is quite acute for several reasons:

the computer has two radiation sources at once (monitor and system unit)

a PC user is practically unable to work at a distance

very long exposure time

Game consoles or set-top boxes that connect to the TV can lead to even more serious consequences. The main problem in this case comes down to the fact that TVs emit a more powerful field, but children (the main category of console users) cannot move away from the screen at a sufficient distance due to short wires, furniture placement, or the picture simply becomes very small. Old television receivers (domestic "Rassvet", "Rubin") are especially dangerous - their EM background is several times higher than that of modern world brands (Sony, LG, Panasonic, etc.). After 5-8 hours spent in front of such a TV (which is not uncommon in our families), the child gets a fever, the temperature quickly rises, and a headache appears. In this case, children should be immediately taken out of the EM field area, preferably outside. Symptoms quickly disappear after cessation of exposure to EM radiation.

The frequency range of electromagnetic waves currently recorded extends from 0 to 3*10 22 Hz. This range corresponds to the spectrum of electromagnetic waves with wavelengths varying from 10-14 m to infinity. Based on wavelength, the spectrum of electromagnetic waves is conventionally divided into eight ranges. The difference in frequencies emitted in different ranges is due to the difference in microscopic radiation sources. The main sources of electromagnetic radiation in modern human life are:

electric transport – trams, trolleybuses, electric trains.

power lines - city lighting, high-voltage lines.

household electrical appliances.

TV and radio stations - broadcasting antennas.

satellite and cellular communications - broadcasting antennas.

personal computers.

Each of these sources creates electric and magnetic fields in a different frequency range from 0 to 1000 Hz. In this case, such values ​​of magnetic induction B, μT and electric field strength E, V/m are created, which in some cases far exceed the maximum permissible standards (MPN).

EM waves change the environment in the workplace by filling the air with positively charged ions. Such ions are harmful to people, so the room must be ventilated, and the best solution would be to purchase a device known as the “Chizhevsky Chandelier”; currently there are quite a few modifications of them. The Chizhevsky chandelier is a source of negatively charged ions (more popularly known as the “mountain air effect”), which are beneficial to human health.

Content

• Radio wave disease

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 acts on the human body.

The 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. The influence of the electromagnetic field on various functions of a wide variety of living organisms was stable. This applies both to its simplest representatives and to the most highly organized creatures.

However, as humanity “matured,” the intensity of this background began to continuously increase due to artificial man-made sources: overhead power transmission lines, household electrical appliances, radio relay and cellular communication lines, and so on. The term “electromagnetic pollution” (smog) arose. 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 action of electromagnetic fields on a living organism, and what could be the consequences?

In search of an answer, we will have to accept the concept that a person not only has a material body consisting of an unimaginably complex combination of atoms and molecules, but also has another component - an electromagnetic field. It is the presence of these two components that ensures a person’s connection 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 vibrations, so the changes they cause can be very diverse. The nature of the consequences is influenced not only by the frequency, but also by the intensity and time of exposure. Some frequencies cause thermal and informational effects, others have a destructive effect at the cellular level. In this case, decomposition products can cause poisoning of the body.

Norm of electromagnetic radiation for humans

Electromagnetic radiation turns into a pathogenic factor if its intensity exceeds the maximum permissible norms for humans, verified by many statistical data.

For radiation sources with frequencies:

• 30-300 kHz is a field strength of 25 V/m;
• 0.3-3 MHz - 15 V/m;
• 3-30 MHz - 10 V/m;
• 30-300 MHz - 3 V/m;
• and from 300 MHz to 300 GHz - 10 μW/cm2.

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. When the intensity of electromagnetic radiation exceeds the specified values, negative health effects are very likely. The actual voltage values ​​of the power line are 5-6 times less than the dangerous value.

Radio wave disease

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 all the most important systems in his body. 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, poor concentration, depression - are not particularly specific, so diagnosing this disease is difficult.

However, later 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, let’s consider its effect on different systems of the body.

Impact of electromagnetic fields and radiation on the human body

1. The human nervous system is very sensitive to electromagnetic effects. Nerve cells of the brain (neurons) as a result of the “interference” of external fields deteriorate their conductivity. This can provoke severe and irreversible consequences for the person himself and his environment, since the changes affect the holy of holies - higher nervous activity. But it is she who is responsible for the entire system of conditioned and unconditioned reflexes. In addition, memory deteriorates, coordination of brain activity with the work of all parts of the body is disrupted. Mental disorders, including delusions, hallucinations and suicide attempts, are also very likely. Violation of the body's adaptive ability is fraught with exacerbation of chronic diseases.

2. The reaction of the immune system to exposure to electromagnetic waves is very negative. Not only does the immune system become suppressed, but the immune system also attacks its own body. This 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 become victims of electromagnetic radiation.

3. Blood quality plays a paramount role in human health. What is the effect of electromagnetic radiation on blood? All elements of this life-giving liquid have certain electrical potentials and charges. Electrical and magnetic components that form electromagnetic waves can cause destruction or, conversely, adhesion of red blood cells, platelets, and cause obstruction of cell membranes. And their effect on the hematopoietic organs causes disruptions in the functioning of the entire hematopoietic system. The body's reaction 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 conductivity and can cause arrhythmia. The conclusion is not comforting - electromagnetic radiation has an extremely negative effect on the cardiovascular system.

4. 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 important hormones.

5. One of the consequences of disorders in the nervous and endocrine systems is negative changes in the sexual sphere. If we evaluate the degree of influence of electromagnetic radiation on male and female sexual function, then the sensitivity of the female reproductive system to electromagnetic influences is much higher than that of men. Associated with this is the danger of affecting pregnant women. Pathologies of child development 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 embryo is still loosely attached to the placenta and an 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 symptoms indicate the strongest biological influence of electromagnetic radiation on human health. The danger is aggravated by the fact that we do not feel the impact of these fields and the negative effect accumulates over time.

How to protect yourself and your loved ones from electromagnetic fields and radiation? Following the following recommendations will help minimize the consequences of using electronic household appliances.

Dosimeter

1. First of all, determine the degree of danger posed by various sources of electromagnetic radiation in your home.

2. Buy a special dosimeter.

3. Turn on the microwave oven, computer, cell phone, etc. one by one, and measure the dose recorded by the device.

4. Distribute your existing radiation sources so that they are not grouped in one place.

5. Do not place electrical appliances near the dining table or rest areas.

6. Check the children's room especially carefully for sources of radiation, remove electric and radio-controlled toys from it.

7. Check for grounding in the computer socket.

8. The radiotelephone base emits 24 hours a day, its range is 10 meters. Don't keep your cordless phone in your bedroom or on your desk.

9. Do not buy “clones” - fake cell phones.

10. Household electrical appliances should only be purchased in a steel case - it screens the radiation emanating from them.

Our everyday life includes more and more diverse technology that makes our lives easier and more beautiful. But the influence of electromagnetic radiation on humans is not a myth. The champions in terms of influence on humans are microwave ovens, electric grills, cell phones and some models of electric shavers. It is almost impossible to refuse these benefits of civilization, but we should always remember about the reasonable use of all the technology around us.

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 the signals sent by hormones of the parathyroid glands on cell membranes, inhibition of the growth of bone material 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 long-term repeated exposure to maximum permissible EM radiation (especially in the decimeter wavelength range) can lead to mental disorders.
