选择湖南省内具有代表性的A,B,C三处铀矿冶设施,深入调查了设施本身及周边环境的放射性污染现状.调查内容主要包括铀矿山及其周边邻近区域内介质中的空气氡浓度、γ辐射空气吸附剂量、铀矿区水(泉水)和土壤中放射性核素含量.调查结果显示,C矿区的个人剂量值明显低于退役治理行业标准,表明C铀矿区退役治理效果较好,而A矿区和B矿区的个人剂量值均略高于退役治理行业标准,有待进一步治理.根据调查结果提出了具体的、有针对性的治理措施和建议.表2,参8.
This paper investigates the radioactive pollution in three representative uranium mines that are respectively denoted as A, B, C in Hunan province. The contents of the investigation mainly include the air radon concentration, the ~/radiation adsorption dose, the radionuclide ( such as ct and [3 ) content of water and soil. The results show as follows: The individual dose value in C uranium mine is lower than the standard value, which represents the countermeasures make a good effect in C. Meanwhile, the indi- vidual dose values both in A and B are higher than the standard value, which indicates more effective measures are needed to be taken in A and B. Moreover, some concrete strategies for dealing with the radi- oactive pollution have been proposed in this paper. 2tabs.8refs.
