摘 要:从射频电磁辐射水平的角度,对广州市一般环境电磁环境质量进行了探讨。通过深入分析2008—2017年10年内广州市区9个国控监测点16次监测的历史数据发现,广州市射频综合电场强度整体呈现逐年增加的趋势,年平均值从2008年的0.51V/m上升到了2017年的1.01V/m,但所有监测点的射频综合电场强度均远低于公众曝露控制限值(12V/m)。商业区的射频电场强度明显高于风景区、文教区,且增速较快。分析结果表明,广州市整体电磁环境现状良好,电磁环境容量较大,还需要密切关注商业区的电磁辐射水平。This paper discusses the overall electromagnetic environmental quality in Guangzhou City, in terms of the radiofrequency electromagnetic radiation levels. The historical data of the radio frequency electromagnetic radiation levels were analyzed, which were obtained from 16 times of monitoring at 9 state-controlled monitoring sites in Guangzhou in the past ten years (2008-2017). It was found that the overall levels of radiofrequency electromagnetic radiation generally increased from 0.51 V/m in 2008 to 1.01 V/m in 2017. However, the annual average values at the monitoring sites were all below the guideline value of public exposure (12 V/m). In addition, the levels of radiofrequency electromagnetic radiation in the commercial districts, which increased recently, were much higher than those in scenic and education areas. The findings of this study demonstrate that the good overall electromagnetic environmental quality and the high electromagnetic environment capacity in Guangzhou. However, the increasing electromagnetic radiation levels in the emerging commercial districts should be considered closely in future.
