摘要: 介绍了广东省某铀矿富集区及其周边约700 km2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238U、232Th、226Ra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。

关键词: 铀矿富集区, 环境放射性, γ辐射剂量率

Abstract: A survey of environment radioactivityin and around a uranium enrichment area of approximately 700 km2 in GuangdongProvince has been made. The result shows that the gamma radiation dose rate is far higher than the provincial natural radioactivity level. 238U, 232Th, 226Ra in some soil samples are more concentrated than thebackground 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 anda hydrometallurgy factory exceeds the nuclear industrial limit.

Key words: Uranium enrichment area, Radioactivity, Gamma radiation dose rate
