摘　　要：为了进一步加强对放射性废物库的安全管理,确保辐射环境安全,对2013—2018年山西省放射性废物库库区环境γ辐射剂量率的监测结果进行了分析。结果表明,库区环境γ辐射水平满足《核技术利用放射性废物库选址、设计与建造技术要求(试行)》中有关库房内源坑盖板上方0.5 m处γ辐射剂量率不超过20μGy/h、源库墙外表面0.2 m处γ辐射剂量率不超过2.5μGy/h的规定要求,各年度间环境电离辐射水平处于本底涨落范围内,未对周围环境产生辐射影响,辐射环境质量总体良好。此外,健全的库区安全防范也为促进我省核技术利用和安全、健康、可持续发展提供了坚强保障。To strengthen the safety management of radioactive waste repository,and to ensure the environmental radiation safety,this article analyzed the monitoring results of environmental gamma radiation dose rate in radioactive waste repository from 2013-2018 in Shanxi province radioactive waste repository.Results showed that the environmental gamma radiation levels at the repository meet the"Technical requirements for siting,design and construction of radioactive waste repository for nuclear technology application(Trial)".The gamma radiation dose rate at 0.5 m above the top of sources pit cover within the repository building is less than 20μGy/h.The gamma radiation dose rate at 0.2 m from the outer surface of the repository building wall is less than 2.5μGy/h.The annual environmental radiation level within the fluctuation range of background,which did not produce radiation effects of on the surrounding environment.Radiation environmental quality is generally good.In addition,a robust security level in the repository area will provide a strong guarantee for promoting the use of nuclear technology and the safety,health and sustainable development of the province.
