Is there any radiation from the telecommunications terminal equipment?
Microwave is mainly through the launch of high-power micro-beam to harm the human organ is mainly the nervous system, reproductive system, eye, etc., on the cardiovascular system, liver also have significant damage effect.
Electromagnetic pollution is the fourth largest public hazard
National Institute of Electronics Electrotechnical Committee Zhao Yufeng teach
It is said that any charged body has electromagnetic radiation, when the electromagnetic radiation intensity exceeds the national standard, it will produce negative
Surface effect, causing human disease. At present, electromagnetic pollution has been recognized as the following air pollution, water pollution,
Noise pollution after the fourth largest human pollution.
According to reports, in our lives, electromagnetic radiation pollution is everywhere, there are television broadcasting tower,
Radar station, communication transmitter, substation, high voltage wire, as well as electronic equipment, medical equipment, automation
Equipment and computers, mobile phones, microwave ovens, cookers, and even subway trains can make electromagnetic radiation pollution.
National Radio Interference Standardization Committee of the relevant experts in an interview with reporters that electromagnetic radiation
The intensity of a look at the frequency, the electromagnetic wave has long wave, medium wave, short wave, ultrashort wave, microwave, frequency increases,
The higher the frequency, the greater the impact; second look at the distance, the closer, the greater the harm to people, especially high power
High-voltage line or high-power launch pad near the body by the more obvious harm. In addition, but also look at the angle,
Electromagnetic waves are directional, and the radiation from different angles is different.
This combination of factors, coupled with labor protection agencies test that mobile phone base stations and paging
Antenna, generally built in high-rise, due to the floor and the surrounding buildings of the barrier refraction, the general floor of the building
People and nearby residents will not have adverse effects. Of course, if happens to your height with the phone antenna
On a plane, and
The distance is only 10-20 meters, that affected by the much greater impact. Radio and television transmission tower power,
The impact on the surrounding residents is slightly larger.
Experts, before the high-voltage transmission lines, radio towers and other construction around the very open, but with
With the expansion of the city, and now some residential areas from the high-voltage lines and even only a wall separated, the building is also higher and higher,
The possibility of being subjected to electromagnetic radiation is enhanced. However, due to the various factors are more complex, must pass
Professional bodies of the field determination, in order to determine a place by the exact value of electromagnetic radiation.
Prevention of electromagnetic pollution
In order to control the harm of electromagnetic waves to the environment, China's health sector and environmental protection departments have formulated the relevant norms,
For example, the Ministry of Health's "Environmental Radio Health Standards" stipulates that people often live, work and live
The ambient electromagnetic wave allows the radiation intensity standard to be divided into two levels. Level 1 is a safe area. Various transmit antennas,
