楼顶式移动基站电磁辐射污染调查

对南通市楼顶式移动基站电磁辐射污染进行了调查。结果表明,南通市418个楼顶站基站周边地面50 m范围内电磁辐射功率密度值均能满足《电磁环境控制限值》(GB 8702—2014)的要求;楼顶美化天线、集束天线和景观塔等建设较晚的楼顶塔形地面电磁辐射强度相对较小,楼顶角钢塔、拉线塔和抱杆等建设较早的塔形地面电磁辐射强度相对较大;楼顶塔所在楼顶平台监测值存在轻度超标的情况。提出,应严格控制楼顶塔所在楼顶的人员可达性,即基站电磁辐射防护区应高出楼顶2 m以上,避免公众进入基站电磁辐射防护区内,受到基站天线的过量辐射影响。

The Characteristics of Electromagnetic Radiation Pollution of Roof type Mobile Base Stations

This paper investigated the electromagnetic radiation pollution of roof-type mobile base stations in Nantong.The results showed that the power density of electromagnetic radiation of the 418 roof-type mobile base stations in Nantong within the range of 50 m could meet the limit value of “electromagnetic environment control limits” ( GB 8702—2014 ) .Electromagnetic radiation of the newerroof-type base stations such as beautification antenna, bundling antenna and landscape tower was relatively low.Electro-magnetic radiation of the olderroof-type base stations such as intensity corner of the roof tower, cable tower and the holding pole was relatively high.Electromagnetic radiation at the roof where the stations were based exceeded the standard slightly.It was suggested that restrictions should be set to control personnel accessibility to the roof, namely base station electromagnetic radiation protection zone should be at least 2 m higher than the roof to avoid public access to the base station under the influence of the base station an-tenna radiation overdose.
