Abstract: 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 20 μGy /h.The gamma radiation dose rate at 0.2 m from the outer surface of the repository building wall is less than 2.5 μGy/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.
