摘要
介绍 1993～ 1998年间秦山核电站周围环境中沉降物总 β活度的测量方法与结果。连续 6年监测结果表明 :秦山核电站周围环境中 5个沉降物监测点位的总 β年平均放射性水平为 0 74～0 88Bq·m- 2 ·d- 1,平均值为 0 81Bq·m- 2 ·d- 1,低于杭州市沉降物总 β本底值( 0 99Bq·m- 2 ·d- 1)。
It is instructed that measurement method and results of the gross β activity content in fallout at the surrounding environment of Qinshan Nuclear Power Plant(NPP) during 1993～1998.The average is 0.81 Bq.m-2.d-1 at the 5 points.It is lower than gross β activity content in fallout of Hangzhou.It is indicated that the gross β activity content in fallout do not obviously rise at the surrounding environment of Qinshan NPP.
