目的了解秦山核电站运行17年后是否对上海地区环境和居民健康产生影响.方法通过现场监测和采样分析方法对上海金山地区室外环境与饮用水、食品、土壤等环境介质中的放射性水平进行监测.结果室外天然辐射水平与环境介质中的放射性水平属正常本底范围,核电站运行前后金山地区环境放射性水平无明显变化,环境介质中的放射性水平低于国家标准限制浓度;居民受室外天然辐射外照射所致剂量为0.102 mSv,经由膳食摄入人工放射性核素90Sr和137C8所致居民内照射剂量为0.488μSv.结论秦山核电站运行17年所释放的放射性物质未对上海地区环境放射性水平和居民健康产生影响.

Objective To study the effect on the environmental radioactivity level and the health of the residents in Shanghai when Qinshan Nuclear Power Station(QNPS) has been in normal operational condition for 17 years. Methods The field monitoring and the sampling analytical method were used for monitoring the radioactivity level in outdoor environment, drinking water, food and soil. Results The outdoor natural radiation level and the radioactivity level in the sample of the environmental media were on the normal background level. There was no distinct change in the environmental radiation level of Jinshan Area when QNPS was in normal operational condition. The radioactivity level in the environmental media was far lower than the limit values specified by the national standard GB. The effective dose of the outdoor natural external exposure for the residents is about 0.102 mSv/a and the effective dose of the internal exposure from the artificial radionuclides 90Sr and 137Cs in food for the residents is about 0.488 μSv/a. Conclusions There is no effect of the radioactive contamination on the environmental radioactivity level and the health of the residents in Shanghai when QNPS has been in normal operational condition for 17 years.
