Shanghai: Whole city's 3G base station electromagnetic radiation are lower than national standards

This year the city needs to add more base stations, yesterday, the Urban Radio Authority meeting held on the topic revealed that the city's communication base station electromagnetic radiation control standards stricter than the national standards; to nearby residents for the base station does not reflect the physical problem, the city of Institute of Occupational Disease Prevention and Control for three consecutive years according to the epidemiological investigation and research results show that there is no evidence that the residents can reflect electromagnetic radiation and the discomfort of the. At present, Shanghai Mobile, Telecom and China Unicom to build three operators have about 9900 base stations , of which 4700 base stations, outdoor and indoor wireless signal distribution system 5200. City radio Xu Zhen, deputy director of the Authority said that the city building departments to exercise strict base stations reporting and review system, the base station electromagnetic radiation control standards and strict on national standards.

Promulgated in 2005 "in Shanghai set up a public mobile communications base stations, management of the implementation details," and specifically the provisions of the city region of electromagnetic radiation of all base stations to less than 20 micro watt / square cm (the national standard is 40 micro-watts, than the European Germany, the most stringent standard is even lower). in accordance with the requirements of the new base station must be far away from the city's kindergartens, schools, hospitals. According to Shanghai Mobile to disclose the relevant person in charge by a third-party acceptance testing, as of now, the city opened a total of 3G base station electromagnetic radiation and the city are lower than national standards. Last month, the city commissioned the Radio Authority in the relevant departments of Xuhui, Putuo District, such as 68 mobile base stations for 3G field testing of electromagnetic radiation, the results are meet the standards at the national level.

Municipal Radio Administration yesterday to provide a material that the electromagnetic radiation from base stations weak to affect human health. For some people near the base station does not reflect the problem of the body, the Urban Institute of Occupational Disease Prevention and Control for three consecutive years according to the epidemiological investigation and research, The results there is no evidence that the residents can not apply said electromagnetic radiation and related phenomena. It is learned that the mobile communication base station transmitter power density is normally in the 0.6-2.0 micro-watts / square cm, belonging to low-frequency radiation. Under normal circumstances, the installation of base station antennas from 15-50 m ground buildings or towers, the long period of time away from the base station in range of 10-20 meters, can be affected by radiation. Furthermore, the electromagnetic waves in general, after passing through the wall 4 times to decay.

Zhen Xu revealed that the future of mobile, China Unicom, telecommunications operators, the three base stations will be a total of more stations, to reduce the overall number of base stations throughout the city.
