山西广播电视卫星地球站电磁辐射环境影响评价

Environmental Impact Assessment of Electromagnetic Radiation at Shanxi Broadcast TV Satellite Ground Station

报道了对山西广播电视卫星地球站环境影响的评价工作。电磁辐射环境现状调查结果表明 ,评价区环境电磁辐射最高值为 4 .72 5× 1 0 - 5 μW/cm2 ,属正常环境水平 ;发射天线对地面环境电磁辐射贡献最大为 3 .0 2× 1 0 - 6μW/cm2 ;高功放室对工作岗位电磁辐射贡献最大为 3 .1 6μW/cm2 ;同时 ,计算了天线前方建筑物的允许建筑高度。

This report is to present an EIA effort made for electromagnetic radiation at Shanxi Broadcast TV satellite earth based station.The results show that the electromagnetic radiation level within the assessed area is at the maximum of 4.725×10 -5 μW/cm 2,falling within the range of the normal environmental level.The highest value of electromagnetic radiation onto the earth level contributed by transmitting antenna is 3.02×10 -6 μW/cm 2,and the highest value from high power amplifier to the workplace is 3.16 μW/cm 2,with the permitted building height ahead of antenna calculated.
