摘要/Abstract

摘要： 本文介绍了国家辐射环境监测网2011—2015年运行核电基地周围辐射环境监督性监测概况。监测结果表明:运行核电基地周围实时连续空气吸收剂量率未监测到因核电厂运行引起的异常;福清核电基地周围环境介质中人工放射性核素活度浓度未见异常,处于本底水平;虽然秦山、大亚湾、阳江、田湾和宁德核电基地周围部分环境介质中氚活度浓度与核电基地运行前本底相比有所升高,红沿河核电基地周围个别空气样品中碳-14活度浓度高于本底水平,大亚湾核电基地周围个别空气样品检出微量气态放射性碘-131,秦山、大亚湾和宁德核电基地周围个别牡蛎样品中检出微量的银-110 m,但评估结果表明,核电基地运行所致公众个人年有效剂量远低于国家规定的剂量约束值。

Abstract: In this paper, the summary of environmental supervisory monitoring around operating NPP bases in national environmental radiation monitoring network during 2011—2015 period was introduced. The monitoring results showed that in NPP bases surroundings, no abnormality of real-time gamma dose rates caused by NPP bases operation was monitored; Artificial radionuclide activity concentration was normal in ambient environmental medium of Fuqing NPP base; The tritium concentration in part of the environmental medium around Qinshan NPP base, Dayawan NPP base, Yangjiang NPP base, Tianwan NPP base and Ningde NPP base was increased compared with the background level before the operation of NPP base; The carbon-14 concentration in few air samples around Hongyanhe NPP base was above the background level; Traces of gaseous radioactive iodine-131 in few air samples around Dayabay NPP base were detected; There were traces of Ag-110m in few oyster samples around Qinshan NPP base, Dayabay NPP base and Ningde NPP base. However,the evaluation results showed that the public individual annual effective dose caused by the operation of NPP bases was far below the dose constraints value stipulated by government.
