Will it influence people's health that the base station of mobile communication increase?

Will it influence people's health that the base station of mobile communication increase?
People hope one's own mobile phone easy to play, get anywhere have signal, it solves most effective way of problem this to be adding and building the base station of mobile communication, reduce the blind area. At the end of September this year, company GSM the seventh stage of project completes the mobile communication of Hebei, newly-built, more than 2000 dilatation base stations, have realized the city covers stereoscopically, covers completely in the plain area and basically cover in the mountain area countryside. However, someone suspects, the reason is that the electromagnetic wave that the base station launches has injury on human body in adding and building the base station of mobile communication. As to this, the mobile communication company often explains like this: People live in a very complicated electromagnetic wave environment at any time objectively, watch TV, use the computer, mobile phone, microwave oven, which one does not have electromagnetic wave? So long as not excessive, would not influence the health. It is reported, the characteristic of the electromagnetic wave is lossing very fast in the air, generally speaking, in inverse proportion to the square of distance. Safety standard that our country make 900 frequency band (whom mobile communication take this frequency band) now Should not be higher than 40 microwatts square centimeter (power density unit) ,And single the intersection of transmission and power of base station get the standard 1/5 strictly, namely 8 microwatts square centimeter. Relatively come to look, most of some countries of Europe all carry out 900 MHZ of standards that frequency band is not higher than 200 microwatts square centimeter now, 5 times higher than our country, standard of our country wants strict a lot of. The expert thinks, the safety standard that our country makes is scientific at present. Is the electromagnetic wave that the movement base station that the high density is distributed launches excessive on earth? The above-mentioned explanation of the mobile communication company has not taken out the convincing evidence. For this reason, the commmunication company of Hebei begins from April of this year, asks the department in environment protecting mode to appraise the test for 6 months to the electromagnetic wave radiation of the base station, have chosen the traffic peak period making spot check and analyzing to 131 representative base stations, especially lay particular emphasis on appraising the impact on sensitive areas such as the inhabited region, administrative area and public activity region,etc. of electromagnetic radiation of base station of mobile communication, get a large number of full and accurate and accurate data. It shows to measure the result, power value of radiation is 0.02- 0.08 microwatts square centimeter within 50 meters of radius of base region of aerial tower of rural base station, beyond 50 meters of radius is 0.06- 0.14 microwatts square centimeter, well below the maximum limit of 8 microwatts square centimeter. The power density value of the sensitive place of environment outside 30 meters from aerial of the urban base station is lower than the limit of 8 microwatts square centimeter. Come from State General Bureau of Environmental Protection, Northern Transportation University's resisting the expert panel that the electromagnetic expert who interferes with organizations such as research center and the 54th of Ministry of Information Industry,etc. makes up, as to this comment on the project to pay and examine finally, confirm that tests the conclusion and measures the data truly and can be believed. A person in charge of Hebei mobile communication Company says, the communication network formed by numerous mobile communication base stations at present can be rated as " green network " ,People are totally unnecessary to be stricken with anxiety and fear with this. And as you walk in the street, five or six persons around phone at the same time, the mobile phone may exceed the radiating amount to you of the base station to your electromagnetic wave radiation quantity.
