摘　　要：采用国家标准《水和生物样品灰中锶-90的放射化学分析方法》萃取色层法/发烟硝酸沉淀法对阳江核电站运行前后其周围环境地表水、饮用水的90Sr放射性水平进行了监测。监测结果表明,阳江核电站运行前后其周围环境地表水、饮用水中90Sr活度浓度总体在同一水平,且与对照点90Sr放射性水平相当。The radioactivity level of 90Sr in surface water and drinking water of the surrounding environment before and after the operation of Yangjiang Nuclear Power Plant(YJNPP)was investigated. It was then compared with those for control points. The results show that the concentration of 90Sr is generally at the same level before and after NPP operation, and comparable to those of control points.
