Is it dangerous to live next to a high-voltage line? Life under tension

High voltage power lines cause concern for people living near them. Many people notice that after being under power lines for a long time, their health worsens. There is an opinion that harmful electromagnetic waves change brain cells, disrupt the functioning of the entire body and even cause cancer. But is it really harmful to live next to power lines and what is the opinion of experts on this matter? Danger of power lines: myth or reality? From high-voltage lines, as well as from electrical appliances and wiring, 2 types of radiation are emitted - alternating waves and static fields. For example, you can take an outlet with a voltage of 220 to 240 volts, located 1 meter from a person, and a power line with a voltage of 200 kilovolts, installed 30 meters from a residential building. The strength of the static field decreases with distance. Therefore, an outlet and a power line will have approximately the same impact on people. Regarding alternating waves, they attenuate less, because their strength is directly proportional to the distance from the energy source. If we take similar distances, then the equivalent of an outlet will be a power line with a voltage of 6.5 kilovolts. Moreover, in an apartment, in a country house or in office space There are many sockets installed, there is also electrical wiring and various devices that operate on current. Taken together, their radiation is much more harmful to humans than the waves emanating from power lines. There is no information that 100% confirms that living near a high-voltage line is dangerous. This topic has not been fully explored. But there is an opinion that for people living near power lines, the latter causes disruption in the functioning of internal organs. But the frequency of industrial current is 50 Hz, and the human body is affected by frequencies that are much lower. But people working with high voltage noted that after a long stay near power lines, they still experienced harmful effects. Most people exhibited the following symptoms: 1. constant malaise; 2. weakening of the immune system; 3.nervousness. This is probably due to the complexity of the profession, which requires high concentration and constant composure. Scientists note that each person has a different degree of perception of strong electric and magnetic fields and static radiation from power lines. The painful condition caused by the negative effects of power lines is called “electrical allergy.” In some countries, a person with such a disease has the right to move to an area far from power lines. Moreover, financial expenses and search for housing are carried out by government agencies. Thus, single people living in a house located next to power lines may be subject to their negative impact to varying degrees. One person will constantly feel the effects of the harmful effects of power lines, while the health of another will remain unchanged. What could be the consequences of living next to a high-voltage line? Presumably, a power line located where a dacha, apartment, office or other premises where people are often located can cause damage to their health. The danger of harmful radiation is the appearance of chronic fatigue syndrome in humans, weakened immunity and increased irritability. Indirect evidence of this is the results of studies conducted at the Karolinska Institute in the USA. Scientists have found that prolonged exposure to electromagnetic fields increases the risk of developing cancer, heart and vascular diseases, impairs reproductive function and contributes to depression. Researchers were able to study the theory of harm from power lines thanks to the participation in the experiment of several thousand people whose lives pass near high-voltage lines. Although exact reasons negative impact It was not possible to determine electromagnetic fields. But scientists suggest that power lines ionize dust particles hovering near them, and then penetrating into a person’s lungs. In the respiratory organs, ions charge the cells, which disrupts their function. Of course, if you spend a long time in a place where there is a high-voltage line, every person will learn about its harmful effects. Such an “unfavorable neighborhood” increases the likelihood of cancer and disrupts the functioning of many body systems: 1. nervous; 2. sexual; 3. immune; 4. endocrine; 5. hematological; 6. cardiovascular. Harmful power lines are especially dangerous for pregnant women, children, allergy sufferers, and people with central nervous system diseases and immunodeficiencies. This is confirmed by reviews of people who have worked in the area of ​​electromagnetic radiation for more than a year. They noted that they developed severe headaches, hypertension and deteriorated vision. And men young Those who have not previously had heart problems often have a heart attack. How do you know if power lines pose a health hazard? How can a person living near high-voltage lines independently determine the degree of influence of electromagnetic fields on the body? It was said above that the transmission distance of harmful magnetic field determined by the power of the power line. Knowing necessary information Even by looking at the wires, you can approximately determine the voltage class of a power line. This will tell you the number of wires in the “bundle” (phase). So, where there are 4 wires the power is 750 kilowatts, 3 - 500 kV, 2 - 330 kV, 1 - less than 330 kV. To establish the class, you need to know the number of insulators in the garland. 220 VK - 10-15 pieces, 35 kV - 3-5 pieces, 110 kV - 6-8 pieces, 10 kV - 1 insulator. To protect people from the effects of magnetic fields, referring to the power of power lines, sanitary protection zones are installed with the projection of the far wire. Below is a list indicating the voltage of the power line and the size of the zone in meters: 1. 750 kV – 40 m; 2. 300-500 kV – 30 m; 3. 150-220 kV – 25 m; 4. 110 kV – 20 m; 5. 35 kV – 15 m; 6. up to 20 kV - 10 m. However, in this table, standards are established for Moscow. But in a number of cases, it is precisely this regulation that is used when allocating sites for development. Although the sanitary standards described above were determined without taking into account the influence of the magnetic field. But today all over the world they are talking about their even greater harm than from electrical radiation. But in Russia and the countries of the former CIS there is no such thing as the level of magnetic fields and it is not standardized at all. Therefore, before buying a dacha, house or apartment near power lines, it is worth inviting an ecologist to conduct a study. Experts will carry out an inspection and give an official, legally confirmed opinion. also in major cities, such as Moscow, you can use the services of specialists from the Association of Independent Laboratories, who will conduct a professional environmental assessment. For those who want to completely protect themselves from the negative effects of magnetic fields, researchers recommend increasing the sanitary protection zone norm tenfold. So, 100 meters is enough so that the human body is not exposed to the influence of weak power lines. And if real estate that is falling apart near high-voltage lines has already been purchased, and there is no way to sell it, then you definitely need to call specialists who can determine the degree of potential danger. Although before today there are no official data regarding the safety of power lines, their negative impact there's no point in denying it. After all, the majority of people living or working near power lines noted that their health is getting worse every year. Therefore, those who are often exposed to electromagnetic radiation need to periodically relax in environmentally friendly areas - outside the city, in the forest, in the mountains or at sea.

In the 60s, specialists in Russia paid attention to the electromagnetic fields of power lines (PTLs). After long-term and in-depth studies of the health of people who have contact with power lines at work, the results of these studies showed that people long time Those who were in an electromagnetic field more often complained of weakness, irritability, fatigue, weakened memory and sleep disturbances.

Currently, there are many problems associated with long-term exposure to power lines on the nervous system, cardiovascular, immune and reproductive systems.

Power line(power lines) - one of the components electrical network, a system of power equipment designed to transmit electrical energy through electrical current.

The wires of a working power line create electric and magnetic fields of industrial frequency in the adjacent space. The distance over which these fields extend from the line wires reaches tens of meters.

Within the sanitary protection zone of power lines it is prohibited:

place residential and public buildings and structures;

arrange parking areas for all types of transport;

locate automobile servicing enterprises and oil and petroleum products warehouses;

carry out operations with fuel, repair machines and mechanisms.

SaNPiN No. 2971-84

And now what happens in reality:

One of the most powerful pathogens electromagnetic waves- industrial frequency currents (50 Hz). Yes, tension electric field directly under the power line can reach several thousand volts per meter soil, although due to the property of reducing soil tension, even when moving 100 m from the line, the tension sharply drops to several tens of volts per meter.

Studies on the biological effects of electric fields have found that already at a voltage of 1 kV/m it has an adverse effect on the human nervous system, which in turn leads to disruption of the endocrine system and metabolism in the body (copper, zinc, iron and cobalt), disrupts physiological functions: heart rate, blood pressure level, brain activity, stroke metabolic processes and immune activity.

As for electricians and other power line workers, the situation is even worse.

Power line personnel experienced visual impairment, changes in color perception, narrowing of visual fields in green, red, and especially blue color, vascular changes in the retina. Studies have been conducted of professionals working 8 hours a day in contact with AMY. Some reported decreased sex drive, a tendency toward depression, and irritability. There was a decreased number of lymphocytes in the blood.

Look what happens to the biofield of a person living near power lines:

Human biofield– this is its electromagnetic field, that is, the totality of radiation from every cell of our body. In fact, any object on Earth, any living organism, has it.

Our electromagnetic field was formed under the influence of the Earth's electromagnetic field. And since today’s electromagnetic background is tens of thousands of times higher than natural, our field cannot withstand such an onslaught.

If our electromagnetic field begins to be affected by other sources of radiation, much more powerful than the radiation of our body, then chaos begins in the body. This leads to a dramatic deterioration in health.

From an energetic point of view, the biofield performs a protective function. It is also called aura. In fact, this is the first protective barrier.

Data:

One of the largest studies of this issue took place in England and Wales from 1962 to 1995.

Were considered medical records more than 29 thousand children under 15 years of age

It turned out that the risk of leukemia in children who lived from birth at a distance of up to 200 meters from power lines is 70%, and from 200 to 600 m – 20%.

Statistics have shown that power lines have a significant negative impact.

"Our study shows that approximately 5 in 400 cases of childhood leukemia can be associated with high-volume lineages, representing about 1% of cases," said Gerald Draper, leader of the research team at the University of Oxford.

The works of Anisimov V.N. provide facts from Swedish scientists:

They analyzed information about the incidence of cancer among people living in close proximity to high-voltage power lines (at a distance less than 300 m).

In a group of 400 thousand. man was discovered 142 children With various types malignant neoplasms and 548 adults with a brain tumor or leukemia.

An examination was also carried out to determine the reproductive function of 542 workers substations Power lines. This analysis allowed us to identify pathologies such as:
1) an increase in the number of congenital deformities if the father worked at a power plant;
2) decreased fertilization function among some male workers
3) The birth rate of boys has decreased.

Was also examined group of youth under 18 years old, living within 150 m from substations, transformers, subways, power lines railways and power lines. They were twice as likely to have disorders nervous system and leukemia.

In Denmark, 1,707 children under 16 years of age were examined during the period. Due to living near power lines, some developed brain tumors and leukemia.

Protection from electromagnetic fields of power lines:

So what should we do??

We understand that if a power line is built near your house, you cannot move it. And not everyone can afford to move today.

And even if you don’t live near power lines, then, believe me, they make a very good contribution to the overall electromagnetic background of the city in which you live.

Already exists today reliable protection from electromagnetic fields and their torsion component.

This must be done because the situation concerns your health and the health of your entire family. Especially if you are young and just planning it, or you have small children.

About the dangers of lines high voltage power transmission they talk a lot and most often in vain. Whatever theories have been put forward about how power lines affect a person, here are statistics on the incidence of cancer of people living in an area with a nearby high-voltage line, and the influence of power lines on brain cells, and even widespread hair loss is associated with closely located high-voltage lines. Let's try to understand this issue and justify what is said but never proven.

So, only two types of radiation can come from power lines, in the form of a static field and alternating waves. In addition to high-voltage lines, the same radiation is produced by electrical wiring and any of the electrical appliances in our houses and apartments. For comparison, let's take one outlet alternating current with a voltage of 220-240 volts, located a meter from a person, and a power line with a voltage of about 200 kilovolts, located at a distance of 30 meters. The strength of the static field becomes smaller in proportion to the square of the distance, so both radiation sources, the outlet and the power line, have approximately the same effect.

In the case of alternating waves, the attenuation occurs much weaker, since their strength is inversely proportional to the distance from the radiation source, and if we take the same distances as in the previous case, then the equivalent of an outlet located a meter away from us will be a power line with a voltage of 6. 5 kilovolts. Please also note that in our home there is not just one outlet, but also meters of electrical wiring, a refrigerator, a TV, a computer, and a bunch of other electrical appliances, and their radiation will be much stronger.

Talk about what high voltage lines Electric transmissions cannot have any harmful effects on the human body. The fact is that this issue has never been fully studied. In theory, the only thing that a nearby power line can cause in the body is resonance of internal organs. However, the industrial frequency of the current is 50 Hz, and there is no such frequency in the human body; lower frequencies influence us. However, people who work with high voltage, including high-voltage power lines, have noted that they experience chronic fatigue syndrome, irritability, and weakened immunity. It is quite possible that the listed symptoms are due to the fact that work with high voltages requires constant composure and attentiveness, in contrast to other jobs, when increased attention is required only periodically.

The issue of the dangers of power lines will remain unstudied for a very long time, and the point is not that there are people for whom it is important that this information remains sealed, although this may well be the case, the point is that Each person has a very different perception of both electromagnetic fields and static radiation from high-voltage lines. In some countries there is even the concept of “electrical allergy”.

People who are especially sensitive to radiation from electrical appliances and high-voltage lines have the right to move to a greater distance from passing power lines. By the way, all costs and search for housing are borne by the government. In our country, the maximum money was spent on was to develop standards according to which high-voltage lines are installed. Residential buildings should be located no closer than 10 meters for a line of 35 kilovolts, 50 meters for 110-220 kilovolts and 100 meters for 330 kilovolts and above. The distance is calculated from the outermost wire to the wall of a residential building.

Another interesting fact, living next door in the same house, two people of the same age can experience different impacts from power lines passing nearby. For one it will have a depressing effect, while for another, on the contrary, it will feel a surge of vigor and strength.

It turns out that indeed high-voltage power lines affect people differently. Perhaps this is precisely what is slowing down research in this area? Although it is quite possible that in reality there is no powerful influence at all, and in both the first and second cases it is simply self-persuasion.

On this moment there is no evidence that power lines are harmful to humans, however, nothing has been written about their harmlessness. Indeed, what is known for certain is that they have a certain effect on the human body, but how detrimentally it affects us remains a mystery.

However, supporters of the opinion that high-voltage lines destroy human body, annually publish dry mortality statistics in areas where there are powerful power lines. Sanitary services, in turn, claim that high-voltage power lines are harmless and provide physical calculations. If you look at this problem sensibly, without giving preference to one side or the other, then you can draw certain conclusions. For example, a drop of water cannot kill a person, but if it methodically drips on his head, then very soon the person goes crazy.

If you spend your whole life under the support of a power line of 330 kilovolts, then naturally there will be a very significant effect of its radiation on your body, but if you are constantly away from power lines and only periodically come into contact with the radiation emitted by them, then you will not see any changes in your body notice.

That is why, if possible, try to get out of the city, at least occasionally, because our cities have long become a kind of energy cesspools, where electromagnetic, static and many other types of energy fields intertwine. Somewhere, influencing each other, they weaken; somewhere, overlapping, they intensify many times and no longer correspond at all. sanitary standards. It is virtually impossible to protect yourself from them, but giving your body a break from their effects is available to almost everyone.

The house is located near high voltage. According to the norms, all distances are observed, even a little further...
But it confuses me...

Tell me, is this dangerous? Doesn't this affect your health?

17-10-2007, 14:23

There was a discussion. Maybe it will help.

Well, they didn’t explain it “scientifically”...

17-10-2007, 14:44

I went looking for physics forums :)

17-10-2007, 15:52

and I’m wondering, we have a dacha next to a high voltage line, it’s currently not working, but who knows, maybe it will work tomorrow...

17-10-2007, 18:17

A high-voltage line is dangerous due to an increased (compared to the norm) level of electromagnetic radiation. From the point of view of everyday life, you may not receive some television programs, your computer may be malfunctioning and cellular telephone, and electronic (quartz) watches show completely conventional time.
If you live outside the sanitary zone of power lines, then your health should not be in any danger. As with any physical factor, there are standards for EMR. The correct size of the sanitary zone of power lines is established according to these standards.
If your dacha is located under a power line, you can only call measurers (for absolutely crazy money) and check whether the radiation complies with the standards. But what to do if it does NOT comply is a big legal question...

I think it's definitely bad.

17-10-2007, 21:43

And for health?! How is this for health?
I’m sharing my experience: I worked for 1.5 years, like our entire department, in a zone of magnetic radiation, without knowing it.
I won’t explain scientifically how it affects health, I’ll just say what happened:
1) for me: as soon as 16.00, everything begins to swim in my eyes, the right side of the monitor screen seems to overlap the left and overlaps it. Terrible headaches all day, I couldn’t go to work without Nurafen, and this at 24 years old!! When they finally decided to call specialists from the SES, they said that everything would now be sealed and that I, as the only woman, would be banned from appearing there at all until the radiation was eliminated - there might be infertility.
2) our leader had terrible headaches, blood pressure surges and began to have heart problems. Before this, there were no such problems until we moved into this premises.
3) a heart attack in one of the employees at 35 years old
4) pre-infarction condition in another employee at 32 years old
Before this, none of them had heart problems, but now they all had it at the same time, and even their heads were constantly splitting at work... :(
Since there was a delay in solving the problem, I quickly quit there.

http://www.ecohome.ru/question/?p=12 Here you can ask your question to an ecologist!

And here's another

Is it possible to somehow determine, without calling specialists, whether the power line poses any danger or not?

The range of propagation of a dangerous magnetic field from a power line directly depends on its power. Even with a quick glance at the hanging wires, you can approximately determine its voltage class. This is determined by the number of wires (but not on the support, but in phase, i.e. in a “bundle”):

750 kV - 4 wires.

500 kV - 3 wires,

330 kV - 2 wires,

Below 330 kV - 1 wire per phase. The class can be accurately determined only approximately by the number of insulators in the garland: 220 kV 10 -15 pcs., 110 kV 6-8 pcs., 35 kV 3-5 pcs., 10 kV and below - 1 pc.

Based on the power of power lines, sanitary protection zones for power lines have been established to protect the population from the effects of electromagnetic fields. SN No. 2971-84 “Protection of the population from the effects of the electric field created by overhead power lines of alternating current of industrial frequency.” The sanitary protection zone is installed from the projection of the outermost wire.

Power line voltage - Size of sanitary protection zone

<20 кВ - 10 м

35 kV - 15 m

110 kV - 20 m

150-220 kV - 25 m

330-500 kV - 30 m

750 kV - 40 m

(note - the table shows the “strict standards” established for Moscow)

Based on these sanitary protection zones, areas for development are allocated.

However, it is worth considering that the above sanitary standards were created taking into account the electrical component of the electromagnetic field, without taking into account the influence of the magnetic field. Despite the fact that the magnetic field throughout the world is now considered the most dangerous to health, the maximum permissible magnetic field value for the population in Russia is not standardized. Therefore, most power lines were built without taking this danger into account.

Based on experience and research, in order to completely avoid the influence of the magnetic field, it is enough to increase the size of the sanitary protection zone by 10 times. That is, 100 meters is enough to not worry about the harmful effects of the weakest power line on you and your loved ones. If the power line is located close to the house, then it is worth inviting specialists to determine more precisely whether such a neighborhood is dangerous or not.

Here's another!
Is it harmful to live near high-voltage power lines?
It has recently been found that being in a strong electromagnetic field - near high-voltage wires - is unsafe for human health. Research conducted by doctors from the Karolinska Institute (USA) has shown that prolonged exposure to strong electromagnetic fields increases a person's tendency to depression, causes problems with reproduction, and increases the likelihood of developing cardiovascular diseases and cancer.

These conclusions were made based on a study of the health of members of several thousand families living near power lines. The exact mechanisms of the harmful effects of power lines are not yet clear to scientists. According to one theory, power lines ionize flying dust particles, which, when they enter a person’s lungs, transfer their charges to cells, thereby disrupting their normal functioning.
Now, perhaps, many summer residents, people buying a cottage or living in their own house, are faced with this problem of finding power line wires near their country house (and often apartments). The problem is complicated by the fact that, unlike smaller sources of electromagnetic fields, it is almost impossible to move power lines or achieve their removal and you have to put up with their presence.
Children, pregnant women, people with diseases of the central nervous, hormonal, cardiovascular systems, with weakened immunity, and allergy sufferers primarily suffer from the effects of electromagnetic fields, the powerful source of which is power lines. Research by many scientists suggests a direct relationship between exposure to electromagnetic fields and the development of cancer.

The range of propagation of a dangerous magnetic field from a power line directly depends on its power. Even with a quick glance at the hanging wires, you can approximately determine its voltage class.

Well, very roughly, to the point of “says absolutely nothing.” I personally encountered a situation where power engineers pumped much more than the rated power through the power line.

18-10-2007, 15:12

Well, very roughly, to the point of “says absolutely nothing.” I personally encountered a situation where power engineers pumped much more than the rated power through the power line.

So there could be even more radiation? Mom dear!:010:

18-10-2007, 16:49

Well, they really intimidated me :)) I’ve lived my whole life side by side with a high-voltage line. Nothing hurts either me or my neighbors after 16 hours. The technology doesn’t even think about glitching. None of the neighbors are dying from cancer.
And my physicist dad says that no one has proven such a harmful effect of high-voltage lines. It’s clear that there is no benefit and it would be better to live away from power lines, but it’s also not worth saying that you’ll stretch your legs right away.

I lived for 34 years in a house where from the wall to the high voltage ATTENTION 5!!! meters. When the house was built in 1961, it was assumed that the power lines would be removed from the city. Then it turned out that they couldn’t bear it and even the design of the house had to be cut down. That's how he stands. Some residents, of course, died during this time, and some residents are already over 90 :)
And the house I live in now is a little further away, but still on the same line.
How can one, I wonder, prove the influence of a high-voltage line?

Long-term stay of people for months and years in the area of ​​power lines that emit electromagnetic vibrations and create an electromagnetic field leads to negative changes in the body. This condition causes disturbances in the nervous, cardiovascular, endocrine, reproductive, hematological, and immune systems and increases the risk of developing cancer pathology.

That is why, in order to protect people from the harmful effects of the electromagnetic field along the high-voltage line, the installation of sanitary protection zones is prescribed, the size of which is set taking into account the voltage of the power line.

In accordance with SanPiN No. 2971-84, sanitary protection zones for alternating current power transmission are determined. In particular, at a voltage of 330 kV, the size of the sanitary protection zone is twenty meters. At 500 kV this value reaches thirty meters. Accordingly, forty-meter protection is provided for lines of 750 kV, and 55 meters for a voltage of 1150 kV.

In these zones, dacha and garden plots are prohibited, not to mention residential and public buildings and structures.

To determine whether high-voltage power lines really have such a detrimental effect on the human body, you can compare the distances and transmitted voltages in these structures with a regular 220 V outlet located in our home a meter away from a person.

Why are high-voltage lines harmful?

Power lines emit static fields and alternating waves. However, the same radiation comes from electrical wiring and from any electrical appliances that are located in our houses and apartments. When comparing a 220 V AC outlet located one meter away from a person and a power line transmitting approximately 200 kV current located thirty meters away, and considering that the strength of the static field decreases in proportion to the square of the distance, both of these radiation sources influence approximately the same.

The calculation shows that the equivalent of an outlet located a meter away from us would be a power line transmitting a current with a voltage of 6.5 kV. In addition, it should be borne in mind that in our house there are several sockets, up to tens of meters of electrical wiring, a TV, refrigerator, computer, and other electrical appliances, whose radiation can be much stronger.

It follows from this that it is not worth asserting that high-voltage power lines have such a detrimental effect on the human body. On the other hand, this issue has not yet been fully studied. Theoretically, a power line located near a home can cause a resonance of internal organs in the body. The industrial frequency of the current is 50 Hz, but there are no organs that respond to similar frequencies in the human body and vibrations of lower frequencies negatively affect the body. Although people dealing with high-voltage power lines often experience:

• irritability,
• decreased immunity.

At the same time, these manifestations may be associated with the need for constant composure, accuracy and attentiveness, which distinguishes this profession from other jobs in which the need for increased attention arises only periodically.

The body's reaction to radiation from power lines

In some countries, people who are very sensitive to the radiation of high-voltage lines have the right to move away from passing power lines, while the costs and search for housing are paid by the government. We spend money on developing standards for the installation of high-voltage lines.

It has been observed that two people of the same age may experience different effects from a nearby high-voltage power line. It can have a depressing effect on one, while another will experience a surge of energy at this time.

The only thing that is known for certain at the moment is that there is no evidence of the harmful effects of power lines on the human body, as well as evidence of their harmlessness. That is, their certain influence on a person is known, but what it consists of is still a mystery.
