中文摘要:
      以南通市为例,采用车载监测法现场实测城区射频辐射公众曝露,按照0.5 km×0.5 km网格尺度展现其分布特征,并分析地区差异及其影响因素。结果表明,南通城区电磁环境公众曝露电场场量为(0.58±0.28)V/m,处于安全水平;城区公众曝露分布呈现北高南低,中心高外围低的特点,随着网格密度增大,高场强值网格数增加;主城区公众曝露电场场量为(0.84±0.47)V/m,移动通信基站是主要污染源之一。高压输变电线路对方法测试结果影响较大,需进行测试路径优化和异常数据的处理。
英文摘要:
      Taking Nantong city as an example, the public exposure to radiofrequency electromagnetic radiation in the urban area was determined in situ by vehicle monitoring method. According to a grid scale of 0.5 km×0.5 km, the distribution characteristics, the regional differences and the influence factors were analyzed. The result showed the field intensity of public exposure to radiofrequency electromagnetic in the urban area is(0.58±0.28)V/m, which was still at safety level. The distribution of urban public exposure tended to be higher in the north while lower in the south, higher in the centre while lower in the outskirt. High field intensity grid increased with the increase of grid density. The field intensity in main urban area was(0.84±0.47)V/m. The communication base station is one of the main pollution sources. High tension cables affected the test results obviously. Therefore, the test path optimization and abnormal data processing should be necessary.
