摘要
介绍1992～2004年，对浙江省秦山核电基地外围环境γ辐射剂量水平的监测结果。监测结果表明：核电基地周围环境2．5km范围内，秦山山顶、前沿站、秦山镇小学、秦联村和蔡陈门5个监测点13年7辐射平均剂量率的范围为82～113nGy／h，5个监测点的总平均值为96nGy／h，接近运行前这些点的平均本底值（93nGy／h），低于对照点（杭州）监测值（101nGy／h）；50h范围内，热释光剂量计（TLD）监测结果γ辐射累积剂量率为90nGy/h，低于运行前本底调查值（111nGy／h）。
The monitoring results of the environmental γ radiation dose levels during 1992 - 2004 in the surrounding areas of QNPP Base in Zhejiang Province is presented in this paper. That indicates that the γ radiation dose rates for 13 years, measured at 5 points （Qinshan Mountain top, Frontier Station, Qinshan Town Primary School, Qinlian Village and Caiehenmen） within 2.5 km of QNPP Base site fallen in the range of 82 - 113 nGy/h, with an average of 96 nGy/h. Those values are close to the background values of 93 nGy/h at those points prior to operation of NPP, and lower than the monitoring value of 101 nGy/h at control points. Within 50 km of the site, the TLD-measured accumulated γ radiation dose rate is 90 nGy/h, below both the background value of 111 nGy/h.
