宁德核电厂锶-90对浙江境内辐射水平的监测分析

摘要

为分析福建宁德核电厂锶-90对浙江境内的辐射水平,对浙江境内环境中锶-90放射性活度浓度进行监测.2012年～2016年的监测结果表明:气溶胶、沉降物、淡水、海水等样品监测结果的平均值分别为1.13×10-2mBq/m3、8.71×10-3mBq/m2·d、2.30 mBq/L、1.80mBq/L,土壤和生物样品监测结果范围分别为0.56～1.18 Bq/kg、0.01～0.68 Bq/kg·鲜.2013年宁德核电厂正式运行发电以来,浙江境内各环境样品中锶-90的监测结果未见明显异常.%The90 Sr radioactivity of Zhejiang province was monitored to analyze the influence of90 Sr in Fujian Ningde nuclear power station on the radiation level of Zhejiang province. The data between 2012～2016 showed that the average90 Sr radioactivity values in aerosol, sediment, freshwater and seawater samples were 1.13 x10-2 mBq/m3, 8.71 x10-3 mBq/m2·d, 2.30 mBq/L and 1.80 mBq/L, respectively. The 90 Sr radioactivity ranged from 0.56 to 1.18 Bq/kg in soil samples, and 0.01 to 0.68 Bq/kgofresh in biological samples. No abnormal90 Sr radioactivity was found in Zhejiang province since the official running of the Fujian Ningde nuclear power station in 2013.
