摘　　要：对田湾核电站1、2号机组周围15种生物中^(137)Cs、^(90)Sr放射性水平进行监测,并对所致的内照射剂量进行估算。结果表明:生物中^(137)Cs、^(90)Sr活度浓度范围分别为0.008~0.208 Bq/kg和0.007~1.010 Bq/kg。依据测定的数据,估算出核电站周围由膳食摄入^(137)Cs、^(90)Sr所致公众年待积有效剂量为:0.67μSv,其中贡献相对较大的是粮食和蔬菜。The radioactivity levels of ^137Cs、^90Sr in 15 kinds of creatures around Tianwan Nuclear Power Station were monitored,and the internal dose was estimated.The results showed that the concentration of～（137）Cs、^90Sr in the organism was respectively：0.008～0.208 Bq/kg and 0.007～1.010 Bq/kg.According to the measured data,the public effective dose by the dietary intake of ～（137）Cs,^90Sr around the nuclear power plant is：0.67 μSv,the largest contribution is grain and vegetables.
