Abstract: The monitoring results of tritium concentration in the surrounding residential areas of Qinshan Nuclear Power Base from 2014 to 2016 were analyzed.Based on the statistical environmental monitoring data,the radiation dose of the surrounding public caused by tritium emission in recent yeas in Qinshan Nuclear Power Base was evaluated.Evaluation results show that the average internal dose caused by tritium emission of Qinlian residents groups of infants,young children,teenagers and adults were 0.59,1.35,1.18 and 0.92 μSv/a respectively,which is far less than the prescribed effective dose of 0.25 mSv/a caused by radioactive effluent of nuclear power reactor release,which was stipulated by《Regulations for environmental radiation protection of nuclear power plant》(GB 6249—2011).Qinlian residential area is located 2.4 km from WNW azimuth of the Qinshan Nuclear Power Base.It can be seen that the tritium emission in Qinshan Nuclear Power Base is stable and controlled,and the environmental and public impact is acceptable.

Key words: Qinshan Nuclear Power Base, tritium, dose
