| 摘 要： | 在工艺流程分析、放射性源项分析,以及环境现状调查的基础上,对某稀土分离项目的放射性环境影响进行了分析、预测和评价。环境放射性水平现状调查与监测表明,评价因子总体在区域环境本底范围内。放射性环境影响预测确定工作人员和公众所受的最大年附加辐射剂量分别为1.622mSv/a和0.029mSv/a,均低于辐射剂量约束值。在落实辐射防护和环境保护措施以后,该项目放射性环境影响符合国家有关法规和标准限值要求。

| Abstract: | Based on the investigation of field actual environment and analysis of radioactive sources,and industrial process techniques,environmental impact of the radioactive from a REE separation project has been analyzed,assessed and forecasted.The investigation and monitoring of actual radioactive in the environment indicated that value of assessment factors remained within the range of natural background level as a whole.The maximum annual individual effective dose for occupational worker and the public were fore... |
