广西城市放射性废物库库区环境γ辐射监测与分析

Monitoring and Analysis of Gamma Radiation Level at Guangxi Urban Radioactive Waste Repository Area

随着我国科学技术快速发展,核技术在各行业应用越来越广泛,广西城市放射性废物库主要用于暂存广西全区核技术利用单位产生的废旧放射源和放射性固体废物,为了解废物库运行后周围环境辐射水平状况,对广西城市放射性废物库库区环境γ辐射监测,分析2013-2018年的γ辐射空气吸收剂量率的监测结果,结果表明,广西城市放射性废物库库区环境γ辐射空气吸收剂量率处于广西天然本底水平范围内,对周围环境和公众未造成影响。

With the rapid development of science and technology in China,nuclear technology is more and more widely used in various industries.Guangxi urban radioactive waste repository is mainly used for temporary storage of waste radioactive sources and solid radioactive wastes produced by the nuclear technology utilization units in Guangxi.In order to understand the radiation level of the surrounding environment after the operation of the waste repository,the environmentalγradiation monitoring was carried out in the reservoir area of Guangxi urban radioactive waste repository,and the monitoring results of the absorbed dose rate ofγradiation in the air of Guangxi urban radioactive waste repository from 2013 to 2018 was analyzed.The results showed that the absorbed dose rate ofγradiation in the air of Guangxi urban radioactive waste repository to the surrounding environment was within the natural background level of Guangxi,and had no impact on the surrounding environment and the public.
