粤北某铀矿田放射性环境地质调查评价

Geological investigation and evaluation of radioactive environment in a uranium ore field,northern Guangdong province

在野外实地调查的基础上,阐述了某铀矿田的主要环境地质问题,根据原野、主要道路及水系等γ辐射剂量率监测结果比值分析,对区内环境的影响程度进行了分析和评价,通过对部分已探明铀矿床(点)、铀矿开采区、水冶尾矿放射性水平进行了监测,并分析了其对环境的影响,分析评价了某铀矿田区地质环境与环境介质中放射性核素含量水平的相关关系,针对目前存在的放射性环境问题,提出了加强环境保护的措施与建议,提出了合理开发利用该区域自然资源的建议。

On the basis of field investigation,this paper expounded the main environmental geological problem of a uranium ore field.According to the ratio analysis of gamma radiation dose rate monitoring results of fields,main roads and water systems,the environmental influence in this area was analyzed and evaluated.The radioactivity of some proved uranium deposits(spots),uranium mining areas and tailings of hydrometallurgy was monitored and analyzed.The paper analyzed and evaluated the relationship between geological environment and radionuclide content in environmental media in a uranium ore field.In view of the existing radioactive environmental problems,the measures and suggestion for strengthening environmental protection was put forward for rational development and utilization of natural resources in the area.
