摘　　要：针对水电站地下洞室作业环境氡及其子体危害性安全评价多停留在定性分析上,危害性定量计算评价还不完善。通过对贵州某水电站地下洞室现场环境氡及其子体评价,计算作业人员在不同接触时间内吸入氡及其子体对人员产生的年均有效接触剂量,提出了作业环境危害防控措施。The safety assessment of radon and its daughters in underground caverns of hydropower station is mostly conducted at the level of qualitative analysis,and the quantitative analysis and assessment of radon and its daughters needs further development.Through the safety assessment of radon and its daughters in a hydropower station in Guizhou,the annual average effective exposure dose of radon and its daughters by workers exposed to radon and its daughters in different exposure time is calculated based on which the prevention and control measures are proposed.
