摘要
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。
Based on the results of atmospheric diffusion tests bothat the site of the Qinshan nuclear power plant and in the wind tunnelalong with the population and diet information around the site,the paperestimated the individual and collective effective dose equivalent fromairborne radioactive materials released under normal and accidentalconditions of the plant,and assessed the resultant impacts on theenvironment.The maximun individual effective dose equivalent at the sitebounary of 0.5km is 2.7×10^(-2)mSv/a,which mainly results from theintake of ^(137)Cs following the airborne wet deposition on the ground Thecollective effective dose equivalent within radius of 80km(including someareas of Hangzhou and Shanghai city)is 1.1 man.Sv/a,and thenormalized dose equivalent is 3.7 man·Sv/GW(e)·a.The individual andcollective dose equivalent commitment due to accidental releases is alsogiven.
