摘要

通过对矿山氡及其子体内照射剂量评价方法的回顾，研究适合于矿山空气环境中氡及其子体吸入所致内照射剂量的计算方法。并应用所研究出的这些方法，结合实测数据来讨论评价方法的优劣。结果表明，由氡及其α潜能浓度估算个人内照射剂量的方法比较适合于估算矿山空气环境中氡及其子体吸入所致内照射剂量；而由平衡当量氡浓度估算个人内照射剂量的方法，其误差比较大，适合于在矿山大范围辐射环境评价中用来确定关键子区与关键人群。

Abstract

In this paper the estimation of method and application of individual radon and its daughters radiation, which is based on the data collection in uranium mine, has been carried out. By use of the method combined with the collected data, the individual dose method of radon and its potential α concentrations is suitable to estimate the personal radiation dose. However, there are more errors with the individual dose method of balancing radon concentration, which can be used to identify key sub-areas and key sub-groups in the large-scale environmental radiation assessment.
