摘　　要：针对广东省四个伴生放射性矿物理选矿项目运行过程中的辐射水平进行监测,使用监测数据对工作人员和周围公众的有效剂量进行计算。计算结果表明伴生放射性矿物理选矿过程对工作人员和公众的照射剂量最大分别为4.60 mSv∕a、0.12 mSv∕a,同时对使用人员实际佩戴的TLD个人剂量计进行验证评价,结果均满足《电离辐射防护与辐射源安全基本标准》(GB18871-2002)的要求,也满足审管部门规定的目标管理值。According to the radiation level in Guangdong Province four associated radioactive mines physical separation in the process of project operation monitoring,using monitoring data to calculate the radiation working staff and the public around the effective dose.The calculation results show that the associated radioactive mines physical dressing process were 4.60mSv∕a and 0.12mSv∕a on the staff and the public the maximum dose,at the same time,use the TLD actually worn by the personnel for verification and evaluation,all the result meet the requirements of《Basic standards for protection against ionizing radiation and for the safety of radiation sources》(GB18871-2002),It also meets the target management value specified by the audit management department.
