大陆槽矿区稀土尾矿再选放射性污染调查研究

The radioactive contamination survey of rewaste slag rebeneficiation in the dalucao mining rare

本文对大陆槽稀土矿区尾矿再选过程进行放射性污染调查研究,分析尾矿再选过程对环境的辐射影响。对γ辐射剂量率、气溶胶中铀、钍总量及氡浓度进行检测,结果表明,稀土尾矿再选过程对周围辐射环境无明显影响,所有样品的检测结果均符合相关国家标准。

This article investigated the radioactive contamination survey of RE waste slag rebeneficiation in the Dalucao mining rare, analysis the radiation effects in waste slag rebeneficiation on the environment.For γ radiation dose rate, total uranium and thorium in the aerosol, the measurement of radon concentration, the test results for all samples are in line with the relevant national standards. Thus, the RE waste slag rebeneficiation has casused no radiological impact on the environment.
