γ辐射源环境影响评价的剂量估算方法

针对环境影响评价中γ辐射源对环境、工作人员及公众的影响,提出剂量估算的基本方法步骤。包括点源的空气吸收剂量率计算,大气反散射辐射剂量率估算,工作人员和公众年有效剂量当量估算,辐射致臭氧产额估算。并指出了γ辐射源环评需要注意的问题。

Dose Estimation Method in Environmental Impact Assessment for Standard Equipment of Measuring Gamma-ray Exposure

This paper introduces the basic method and procedures of dose estimation by studing the impact of gamma radioactive source to the environment, workers and the public in EIA, including air absorption dose rate calculation of point source, atmospheric backscatter estimation, the annual effective dose equiv alent estimation of the workers and the public, estimation of ozone yields by radiation. It also summarized several problems which should be paid attention to in EIA of gamma radioactive source.
