小和山高教园区电磁辐射环境近年演变

根据2008年及2006年对杭州小和山高教园区公共微波辐射源的测量调查、数据分析对比，可以看到：各院校的校园环境的电磁辐射水平持续走高，除了移动通信基站数量净增长加大了环境电磁辐射现状压力以外，建筑物内新安装的无线上网装置和会议报告厅内对通信信号干扰屏蔽装置，也对局部环境的辐射值贡献较高。公共辐射源数量分布已呈现出园区东、西两端与中部几乎一样密集的状态；园区东、西两端辐射水平比2006年明显增加。中国电信公司的移动上网覆盖扩张计划正在加紧实施，移动公司、联通公司的辐射功率密度呈现交叉叠加覆盖的局面。这些事表明辐射总水平仍呈持续稳定增长趋势，暂无见顶迹象。

Evolvement of environmental influence from electromagnetic radiation in Xiaoheshan Higher Education District in recent years

On the basis of measure of electromagnetic radiation in Xiaoheshan Higher Education District （Hangzhou） in 2008 and 2006, the paper points out the electromagnetic radiation average level keeps rising for increase of base stations of mobile communication and equipment of wireless internet in some buildings and shield. The amount of radiation sources are coarctation on all section. Radiation on the east end or west end are increased much now than that in 2006.
