摘　　要：介绍了大亚湾核电基地安全运行20年后周围环境空气、雨水、地表水、地下水、海水和生物样中的^(14)C水平监测情况。监测结果表明:大亚湾核电基地周围环境介质10 km范围内^(14)C的活度浓度随着离核岛距离增加而减小,距离到约7 km时,^(14)C活度浓度降到环境本底水平。The monitoring results of ^14C concentration,is presented,in ambient air,rain water,surface water,groundwater,seawater and biological samples after 20 years of safe operation of Daya Bay Nuclear PowerBase. They show that the ^14C concentration decreases with the distance from Daya Bay Nuclear Power Base.When the distance increases to about 7 km,the ^14C specific activity falls to the environmental background level .
