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 deteriorates.

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 run 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 who work with high voltage have noted that after being near power lines for a long time, harmful effects they still showed up. Most people experienced the following symptoms:

1. constant malaise;
2. weakened immunity;
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 in to varying degrees. One person will experience results consistently harmful influence Power lines, and the health of the other 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 harm their health. Danger harmful radiation consists in the appearance of chronic fatigue syndrome in a person, 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 the 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. This “unfavorable neighborhood” increases the likelihood of cancer and disrupts the functioning of many body systems:

• nervous;
• sexual;
• immune;
• endocrine;
• hematological;
• 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 young men 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 the harmful magnetic field is determined by the power of the power line.

Knowing the necessary information, even from the wires, you can approximately determine the voltage class of the 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 power line voltage and the zone size 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 still talking about more 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 the Association’s specialists 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 is no official data regarding the safety of power lines; their negative impact cannot be denied. 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.

For the first time, the dangerous impact of electromagnetic fields from power lines on human body was discovered in the 60s of the last century. After careful research into the health status of people who come into close contact with power lines in industrial settings, scientists have discovered alarming facts. Almost all of the examined individuals complained of increased fatigue, irritability, memory and sleep disturbances.

To all of the above symptoms that occur in a person after frequent communication with electromagnetic waves of industrial frequency, we can safely add depression, migraine, disorientation in space, muscle weakness, problems with the cardiovascular system, hypotension, visual impairment, atrophy of color perception, decreased immunity, potency, changes in blood composition, etc. etc. The list can be continued with a number of physiological disorders and all kinds of diseases.

Very often, people living near power lines experience cancer, serious reproductive dysfunction, as well as the so-called electromagnetic hypersensitivity syndrome. It is quite scary to hear reports of research by some foreign scientists on the impact of high-voltage power lines on the health of our children. For example, Swedish and Danish researchers discovered that children living at a distance of up to 150 meters from power lines, substations and subways (!) are twice as likely to suffer from leukemia, and almost all of them have nervous system disorders.

In some countries there is such a medical term as electromagnetic allergy. People suffering from it have the opportunity to change their place of residence to another, located as far as possible from sources of electromagnetic radiation. Moreover, all this is officially sponsored by the government! How can the energy sector comment on the possible danger posed by power lines? First of all, they insist that tension electric current in power lines can be different, and therefore it is necessary to distinguish between safe and dangerous voltage. The range of influence of the magnetic field created by power lines is directly proportional to the power of the line itself. A professional can determine the voltage class of power lines offhand. You too can have this knowledge. Everything is quite simple - you need to pay attention to the number of wires in the bundle (not on the support itself). So: 2 wires - 330 kV 3 wires - 500 kV 4 wires - 750 kV The lower voltage class of the power line is determined by the number of insulators: 3-5 insulators - 35 kV 6-8 insulators - 110 kV 15 insulators - 220 kV.

In order to protect the population from the harmful effects of power lines, there are special standards that define a certain sanitary zone, conditionally starting from the outermost power line wire projected onto the ground. So: Voltage less than 20 kV - 10 m, 35 kV - 15 m, 110 kV - 20 m, 150-220 kV - 25 m, 330 - 500 kV - 30 m, 750 kV - 40 m. For some reason, the above standards apply specifically to Moscow and the Moscow region. Naturally, in accordance with them, plots for development are also allocated. The most interesting thing is that these standards do not take into account the harmful effects of electromagnetic radiation, which is sometimes tens and sometimes hundreds of times more dangerous to health!

And now ATTENTION! To prevent the magnetic field from affecting your health, multiply each of the listed indicators by 10... It turns out that the lowest power power line is harmless only at a distance of 100 meters! Power line wires contain voltage that is in maximum contact with the corona discharge threshold. In bad weather conditions, this discharge releases a cloud of oppositely charged ions into the atmosphere. Electric field, created by them, even at a great distance from power lines, can be much greater than the permissible harmless values.

Just recently received the green light new project Moscow government on moving some sections of high-voltage power lines underground. The mayor's office plans to use the vacated area for construction. This is where a logical question arises - will underground power lines be safe for people living above them? Will developers call energy specialists to the area planned for housing construction? Electromagnetic radiation from underground power lines and its impact on the human body, unfortunately, is still poorly understood...

The first to go underground will be the power lines located in the areas of Leninsky Prospect, Mira Avenue and Shchelkovskoe Highway. Next, it is planned to remove the power lines of the North-Eastern Administrative District underground, namely in Northern and Southern Medvedkovo, as well as in Bibirevo and Altufyevo. These territories are already put up for sale and are waiting for their investors. In total, there are more than a hundred power lines and open-type electrical substations in the capital. Potential developers of “power line” lands, and along with them the Moscow government, claim that modern technologies will completely isolate electromagnetic radiation. For this it is planned to use coaxial cables laid in special shielding collectors.

Unfortunately, moving power lines underground is an expensive procedure (costing approximately 1 million euros per 1 km of cable laid), and therefore there is no guarantee that developers will not “save money”. So no one knows whether housing built above power lines will be safe in all respects. Remember, if your house is located very close to power lines (see permissible sanitary standards above), the most the right decision After all, it will be possible to buy a new home located in a safer zone!

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 glitching and cell phone, 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 right size 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 value of the magnetic field 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 more!
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.

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 scared 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 is 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 can 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?
