四川省城市放射性废物库辐射环境质量的监测与调查分析

Monitoring and Investigation on the Radiation Environmental Quality of Urban Radioactive Waste Repository in Sichuan Province

四川省城市放射性废物库是四川省唯一的放射性废物(源)国家二级暂存库,是保证四川省辐射环境安全的重要设施。通过对四川省城市放射性废物库的辐射环境监测方法的介绍,从环境γ辐射剂量率、水和大气总α、总β放射性活度浓度水平、土壤中敏感核素含量等方面,分析了2011~2018年的辐射环境年度监测报告数据。结果表明四川省城市放射性废物库运行良好,辐射环境安全,不存在放射性污染的情况。

Sichuan municipal radioactive waste repository is the only national secondary temporary storage repository of radioactive waste(source)in Sichuan province,it is an important facility to ensure the safety of radiation environment of Sichuan province.In this paper,through the introduction of the radiation environment monitoring method of the urban radioactive waste repository in Sichuan province,the annual radiation environment monitoring report data from 2011 to 2018 were analyzed from the aspects of environmental gamma radiation dose rate,total alpha and beta levels of water and atmosphere,and the content of sensitive nuclides in soil.The results show that the municipal radioactive waste storage in Sichuan province is in good operation,the radiation environment is safe and there is no radioactive pollution.
