介绍了广东省某铀矿富集区及其周边约700 km 2范围环境放射性现状调查。调查结果表明：该铀矿富集区的γ辐射剂量率明显高于广东省天然放射性水平调查值；部分地区土壤样品中238 U 、232 Th 、226 Ra 含量高于广东省天然放射性水平调查值；地表水体中有一条河流的放射性核素偏高，其铀浓度是广东省北江水系报告值的15．7倍；部分铀矿点和水冶厂的水体铀浓度超过核工业控制标准限值。

A survey of environment radioactivity in and around a uranium enrichment area of approximately 700 km 2 in Guangdong Province has been made .The result shows that the gamma radiation dose rate is far higher than the provincial natural radioactivity level . 238 U , 232 Th , 226 Ra in some soil samples are more concen-trated than the background in Guangdong .There is a river with too higher content of radionuclide ,of which U is 15 .7 times than the reported value for Beijiang River in the province .The U concentration in effluents from some uranium ore occurrences and a hydrometallurgy factory exceeds the nuclear industrial limit .
