【摘要】 目的了解珠海市地表环境中电磁辐射污染现况,为动态观察珠海市电磁辐射污染水平变化积累数据,进一步探讨电磁辐射污染防治对策。方法选择珠海主城区5个片区和1个岛作为调查对象,按照1 km×1 km网格方法进行布点,应用意大利PMM公司生产的PMM8053B型电磁辐射分析仪对各监测点电磁辐射综合电场强度进行测量。结果珠海市地表环境中的电磁辐射综合电场强度在0.04～1.64 V/m之间,市区5个片区与外伶仃岛电磁辐射综合电场强度差异有统计学意义(P<0.01);三类场所电磁辐射综合电场强度比较,居民住宅区域电磁辐射综合电场强度与城市道路、公共场所电磁辐射综合电场强度之间差异有统计学意义(P<0.01)。结论珠海市绝大部分地区的电磁辐射综合电场强度在较低水平,但主城区的电磁辐射总体水平要高于外伶仃岛;居民住宅区域电磁辐射水平略低于城市道路及公共场所。更多还原

【Abstract】 Objective To investigate the level of electromagnetic radiation pollution in the terrestrial surface environment of Zhuhai,so as to accumulate dynamic data and explore the countermeasures.Methods Five main urban districts and an island in Zhuhai City were selected as the investigation objects.1 km×1 km grid measuring points were set and the electric field intensity of electromagnetic radiation was measured by the PMM 8053B Electromagnetic Radiation Analyzer.Results The electric field intensity of electromagnetic radiation in the terrestrial surface environment of Zhuhai was between 0.04 V/m～1.64 V/m.It was significantly higher in the five main urban districts than in the Wailingding Island(P<0.01),and statistically lower in the residential areas than in the city roads and in the public places(P<0.01).Conclusions The electric field intensity of electromagnetic radiation in most of the urban districts of Zhuhai is at low level,but that in the main districts is higher than in the Wailingding Island and lower in the residential areas than in the city roads and in the public places.更多还原
