摘要: 对核电厂员工按工作性质、区域进行分组,运用FT-648型测氡仪对核电厂各监测区域采用经湿度校正的双滤膜法测量氡的浓度、总α五段法测量²²²Rn/²²⁰Rn短寿命放射性子体的浓度,研究核电厂工作人员因氡及²²²Rn/²²⁰Rn子体所致年有效剂量,提出高氡区域的具体防护措施。研究结果表明,核电厂中除乏燃料水池外,其他各区域监测数据均比国际辐射防护委员会推荐值低。

Abstract: The staff of the plant was grouped based on their work ranges.The annual effective dose resulted from radon and the decay products of ²²²Rn/²²⁰Rn is studied by measuring radon concentration with double filter membrane method and by measuring the concentration of ²²²Rn/²²⁰Rn short life radioactive decay products with five-count method.Based on the results,specific protection measures are proposed for high radon areas.The study results show that the monitoring data for all areas except the spent fuel pool was smaller than the recommended values by ICRP.
