摘　　要：根据核电站、铀矿山采冶地区周围环境和没有大型放射性物质释放的对照区环境大气气溶胶的放射性监测结果,统计分析了广东省内大亚湾核电、阳江核电、铀矿山、广州市、茂名市、韶关市、台山核电(暂未运行)周围环境大气气溶胶总α、总β和7Be的活度浓度,比较了核设施运行前后和日本核事故期间环境大气气溶胶放射性水平的变化。According to the monitoring results of ambient air aerosol in the surrounding area of nuclear power plants,uranium mining areas,control areas without large-scale release of radioactive materials,statistical analyses were carried out for grossα,grossβand7Be in aerosol samples from around Daya Bay NPP,Yangjiang NPP,Taishan NPP(not running),uranium mining areas,Guangzhou City,Maoming City and Shaoguan City.The changes of aerosol radioactivity levels before and after the operation of nuclear facilities,and those for Fukushima nuclear accident,were compared.
