Concern the electromagnetic environment around them ——关注身边的电磁环境 作者：???? 来源：中国环境报???? 发表时间：2006-06-19???? 字号：大??中??小 Over the past 20 years, Chinas economy and the rapid development of urbanization, urban area more complex electromagnetic environment, the emergence of many new phenomena and new problems. All types of cities Typical electromagnetic radiation equipment for the testing and analysis of the radiation characteristics, should make a correct understanding and treatment of the electromagnetic radiation exists in our side. electromagnetic radiation refers to energy sources in the form of electromagnetic wave phenomenon launched into space. Electromagnetic environment exists in a given place the sum of all electromagnetic phenomena. Deterioration of the electromagnetic environment not only for human life is increasingly dependent on communications, computers and various electronic systems pose serious hazards, and human health will be at risk. For countries of the world attached to the increasingly complex electromagnetic environment and its widespread impact, electromagnetic environmental protection and electromagnetic compatibility technology has become a rapidly developing new disciplines. With the rapid economic development and urbanization, urban space electromagnetic environment becomes more complex, but also the emergence of many new issues. For example, the urban development and expansion, some large and medium-sized radio and television stations and radio communications transmitters are surrounded by the new development areas, local residents living quarters a strong market areas; Mobile communications technology is developing rapidly, city urban high-rise buildings hundreds of thousands of mobile communications base stations fired, Although each of these electromagnetic radiation little power (100W below), but because blossom everywhere in the urban area to urban high-altitude electromagnetic field-strength increased, local high-rise buildi
