【摘要】 自1992年以来,浙江省辐射环境监测站对秦山核电基地周围环境放射性水平进行了连续监督性监测。2011~2015年基地周围环境饮用水总α总β放射性水平监测结果表明:在正常运行下,秦山核电基地周围环境饮用水总α活度浓度均小于探测限,总β活度浓度范围为0.13~0.92 Bq/L,平均值为0.29 Bq/L。与对照点在同一水平,均低于《生活饮用水卫生标准》(GB 5749-2006)中规定的放射性指标指导值,未见异常。更多还原

【Abstract】 Since 1992,a continuous surveillance was made of environmental radioactivity levels around QNNP(Qinshan Nuclear Power Plant) base by the Environmental Radiation Monitoring Center of Zhejiang Province. The gross α and gross β radiation monitoring of the drinking water in surrounding environment of Qinshan nuclear power base from 2011 to 2015 showed that under normal operation, The gross αactivity concentration of the drinking water was lower than the detection limit, and the gross β activity concentration range is 0.13~0.92 Bq/L, the average value is 0.29 Bq/L. At the same level as the reference point, it was lower than the guideline values of the radioactivity index stipulated in the hygienic standard for drinking water(GB 5749-2006), and no abnormality was found.更多还原
