Radio stations should be kept away

High frequency electromagnetic waves can cause infertility, as evidenced by soldiers working at radar stations that have old equipment, wave leaks that are often inferior. This type of wave is also surrounding ordinary people, from TVs, refrigerators, computers, mobile phones, microwaves .

Recently, people in many places in Hanoi repeatedly "help" in the context of mobile phone service providers installing broadcasting stations right in the residential area, because the electromagnetic waves will be Harmful to their health. According to Dr. Nguyen Khac Hai, Director of the Institute of Occupational and Environmental Hygiene, this fear is not unfounded, because many studies have demonstrated that high frequency electromagnetic waves have a very bad effect. health.

Electromagnetic waves passing through the body will cause the cells to rub themselves together, producing heat; The heat may be so large that it will boil fluid and steam the cells (microwaves operate under this mechanism). With very high doses, electromagnetic waves can cause acute harm. For example, a worker is repairing the radar, standing in front of the broadcasting department; If another person doesn't know, accidentally turn on the device, the worker will faint immediately. If the dose is low, or the distance is not close enough, the effects of magnetic waves can accumulate for a long time and affect the nervous, reproductive, cardiovascular, and visual systems.

Some domestic studies show that postal workers work in broadcasting areas, techniques are prone to health disorders with signs of unhealthy skin, always tired, poor eating, insomnia, memory reduced . The military survey showed that radar personnel had high infertility rates.

Earth is also an object that emits electromagnetic waves. The "thoughtfulness" of nature helps people to be able to adapt to this kind of natural wave. On the other hand, at moderate levels, magnetic waves are also beneficial for health. However, the emergence of more and more electrical devices in the family makes people now live in the midst of a dense wave of words, and they cannot not adversely affect health if people do not know to protect themselves.

To ensure the safety of people, developed countries have set standards for electromagnetic waves in residential areas and industrial zones. However, in Vietnam up to now, only standards have been issued in the working environment without any regulations on the permitted electromagnetic waves in residential areas. Meanwhile, mobile phone base stations are growing more and more, even right next to people's houses. According to the "order" of some families living near the broadcasting station at Linh Dam, Dinh Cong, My Dinh (Hanoi), the Institute of Labor Medicine and Environmental Hygiene has measured electric waves from inside and outside. Their home, the result is that the dose is still within the safety limit (recommended by the world). However, this result does not make people and experts feel comfortable because it is unique.

Up to now, there has never been an official survey of electromagnetic waves in residential areas, so no one can confirm that people living near radio and radio stations. , television does not face the risk of cancer, infertility, cataract . On the other hand, even when there is a survey and the result is that the wave dosage is too high, it is difficult to force the owners of the stations This is corrected because the standard has never been issued.

Dr. Nguyen Khac Hai said that at present, with modern technical equipment, no leakage of waves, the risk of technical staff in the place of broadcasting is not as high as before. But for the people, the danger is getting bigger due to being besieged by the countless electric waves that are dense and very close in the air. On this issue, the Institute of Labor Medicine and Environmental Hygiene has formally proposed the Ministry of Health to conduct a specific evaluation study of high frequency electromagnetic pollution (radio waves) and influence. to urban people's health. The Institute also asked the Ministry to soon build standards for electromagnetic radiation in residential areas.

How to limit the harmful effects of electromagnetic waves

Every electrical device emits electromagnetic waves, its effect depends on the intensity, frequency and distance. In it, only distance is the factor that we can master. Therefore, it is best to stay away from broadcast places, especially high voltage stations (from 220 KV or more), because the magnetic waves here are very strong. When the new North-South 500 KV line was built, there was a study of its impact on people and workers living around, resulting in no acute toxicity. But for the long-term harm, there has never been a survey. Therefore, it is best not to make the house near high voltage area, the minimum distance is 7 meters.

Children should not be allowed to use mobile phones because their waves may affect sexual development, especially reproductive organs. For adults, you should not leave this device in bed. Men should abandon the habit of putting mobile phones in their pockets.

The old, exposed microwave oven needs to be replaced, not to be sorry because the wave in this oven has a strong impact on people. The door of the oven has an iron net that absorbs magnetic waves, but if the door is open, the safety will no longer exist. For safety, it is best not to stand close to the oven when it is running, nor to look at the food in it because the microwaves can destroy the lens.

However, Dr. Hai also advised people not to be too afraid of the harmful effects of electromagnetic waves in household appliances, because their strength is not high, if the device is new, not broken, they are safe. On the other hand, the intensity of magnetic waves decreases very rapidly with distance.
