According to the national "urban planning-related regulations", the general 10,000-volt high-voltage towers and residential buildings horizontal distance is 5 meters, 110,000-volt 10 meters, 220,000-volt 15 meters, 500,000-volt 25 meters, high-voltage towers, then, should try to avoid residential buildings.
The way of prevention
1, improve self-protection awareness, pay attention to electromagnetic radiation may be harmful to the human body, learn more about electromagnetic radiation, learn to take precautions to strengthen safety precautions. Such as: with the application of the manual of electrical appliances, should be strictly in accordance with the instructions of the standardized operation, to maintain a safe operating distance and so on.
2, do not put too much concentration of household appliances, or often used together, so as not to expose themselves to the hazards of radiation overdose. In particular, the TV, computer, refrigerator and other electrical appliances should not be centrally placed in the bedroom.
3, a variety of household appliances, office equipment, cell phones, etc. should try to avoid prolonged operation. Such as television, computers and other electrical appliances need to be used for a long time, should pay attention to at least once every hour to leave, look into the distance or close your eyes in a way that reduces the degree of eye fatigue and the impact of radiation.
4, when the use of electrical appliances suspended, it is best not to let them in standby mode, because this time can produce a weak electromagnetic field, long time will also produce radiation accumulation.
5, the use of various appliances, should maintain a certain safety distance. Such as eyes away from the distance of the TV screen, generally about 5 times the width of the screen; microwave oven after opening to leave at least 1 meter away, pregnant women and children should try to stay away from the microwave oven; cell phone use, should try to make the head and cell phone antenna distance, the best use of separation of the headset and the microphone to answer the phone.
If you have been exposed to excessive electromagnetic radiation for a long time, you should pay attention to the following self-protection measures:
① People who live and work near high-voltage power lines, transformer stations, radio stations, television stations, radar stations, electromagnetic wave towers, patients with pacemakers, people who often use electronic instruments, medical equipment, office automation equipment, and people who live in the automated environment of modern electrical appliances, especially those who live in a modern electrical equipment, should be aware of the need to protect themselves from electromagnetic radiation. Automated environment of the crowd, especially weak resistance of pregnant women, children, the elderly and the sick, the conditions should be equipped with shielding clothing for electromagnetic radiation, electromagnetic radiation will maximize
blocked outside the body.
② TV, computer and other electrical equipment with a display screen can be installed electromagnetic radiation protection screen, the user can also wear radiation glasses to prevent the screen radiation electromagnetic waves directly on the human body.
③ cell phone contact instantaneous release of electromagnetic radiation is the largest, so it is best to ring the phone after a second or two seconds or the phone between two ringtones and then answer the phone.
④ The radiation generated by the screen of the TV, computer and other electrical appliances can lead to dry and dehydrated skin, accelerate skin aging, and seriously lead to skin cancer, so wash your face after using the above electrical appliances in a timely manner.
⑤ Eat more carrots, bean sprouts, tomatoes, greens, seaweed, cabbage, lean meat, animal liver and other foods rich in vitamin A, C and protein, in order to help regulate the body's electromagnetic field disorders, and strengthen the body's ability to resist electromagnetic radiation.
The so-called electromagnetic radiation is the phenomenon of energy in the form of electromagnetic waves emitted from a radiation source into space. Electromagnetic pollution affecting our living environment is divided into natural electromagnetic radiation and man-made electromagnetic radiation. Nature caused by lightning, electricity, such as a class of electromagnetic radiation belongs to the natural electromagnetic radiation category, while man-made electromagnetic radiation pollution mainly includes pulse discharge, frequency alternating magnetic field, microwave, radio frequency electromagnetic radiation.
Such sources of pollution include:
(1) computers, televisions, stereos, microwave ovens, refrigerators and other household appliances;
(2) cell phones, fax machines, communication stations and other communication equipment;
(3) high-voltage power lines, as well as electric motors, motor equipment, etc.;
(4) aircraft, electric railroads, etc.;
(5) Radio and television transmitters, cell phone transmitter base stations, radar systems, etc.;
(6) Power industry machine rooms, satellite ground stations, dispatch and command centers, etc.;
(7) Application of microwaves and X-rays, etc., such as medical equipment.
