摘要
为了解延安市区环境电磁辐射水平,保障公众身心健康,为延安市区规划管理提供技术支持,根据国家有关导则以及延安市区地形地貌特点,以市区四条公路为主干线,沿公路每间隔1km划分若干小方格布点,采用EMR-300电磁辐射分析仪,在100kHz～3GHz频段距离地面1.6m高处测量布点的综合场强值。测量结果表明,延安市区划分的40个测量点基本符合标准要求,仅个别区域的测量点超出一级安全区限制,对附近人群的潜在健康威胁值得关注。
In order to know the environmental electromagnetic radiation level of Yan＇ an city, provide guarantee of public health and technical support for the city planning and management, the integrated electric field intensity of measttrement points were measured using electromagnetic radiation analyzer EMR-300 1.6 meters above the ground during 100kHz - 3GHz. According to the national guidelines and the characteristics of Yan＇ an city landform, the whole city was divided into several squares as measurement points along four main roads every one kilometer. The measurement results show that the 40 measurement points almost reach the standard requirement except very few point intensity exceed one-level security, where the health of people around should be concerned.
