本文评价了秦山核电厂气载放射性流出物对环境的影响。应用现场及风洞大气扩释实验结果和厂址周围的人口与食谱调查资料,估算了秦山核电厂在正常运行和事故条件下释放的气载放射性流出物对公众产生的个人有效剂量当量和集体有效剂量当量。计算结果表明,正常运行时厂址边界(0.5km)处的最大个人有效剂量当量为2.7×10~(-2)mSv/a,该剂量的大部分来自~(137)Cs 的食入(主要由地表湿沉积引起);80km 范围内的集体有效剂量当量为1.1人·Sv/a,归一化集体有效剂量当量为3.7人·Sv/GW(e)·a。文中还给出了事故情况下剂量估算结果。
This paper evaluates the environmental impact of airborne radioactive effluents from Qinshan NPP. Based on the field and wind tunnel experimental results of atmospheric expansion and population and recipes survey data around the site, the individual effective dose equivalent and collective effect of airborne radioactive effluents released by Qinshan NPP to the public under normal operation and accident conditions are estimated Dose equivalent. The calculation results show that the maximum personal effective dose equivalent at the site boundary (0.5km) in normal operation is 2.7 × 10 -2 mSv / a, and most of this dose comes from the ingestion of 137 Cs mainly from Surface wet deposition caused by); 80 km range of collective effective dose equivalent of 1.1 people · Sv / a, the normalized collective effective dose equivalent of 3.7 people · Sv / GW (e) · a. The article also gives the dose estimation results under accident conditions.
