摘　　要：目的 分析重庆市介入放射工作人员个人剂量监测异常结果,联合眼晶体监测和生物剂量检测结果,调查典型案例,为辐射防护提出整改意见。方法 统计2021年重庆市第四监测周期个人剂量异常结果、眼晶体剂量异常结果的介入放射工作人员,采用生物剂量检测和调查表进行调查,并对数据进行分析。结果 2021年重庆市第四监测周期剂量>1.25 m Sv的共49人次,其中介入放射学18人次,9人异常原因为佩戴期间工作量增加。同周期,介入人员眼晶体剂量监测130人次,其中估算年剂量超20 mSv且个人剂量超1.25 mSv的共4人次。眼晶体剂量且个人剂量异常者染色体畸变分析,两人双着丝粒(1)、一人三射体(1)、一人无异常。结论 重庆市介入放射工作人员个人剂量监测异常结果不容忽视,应加强放射工作人员的职业健康监护,提高个人剂量监测异常情况调查,普及重点部位剂量监测,完善放射工作人员职业健康检查项目,做好职业防护。Objective To analyze the abnormal results of individual dose monitoring of interventional radiation workers in Chongqing,investigated typical casescombined with the results of ocular lens monitoring and biological dose detection,,and put forward rectification suggestions for radiation protection.Methods The interventional radiation workers who counted the abnormal results of individual dose and ocular lens dose in the fourth monitoring cycle in Chongqing in 2021 were investigated by biological dose detection and questionnaire,and the data were analyzed.Results In 2021,a total of 49 people with a dose>1.25 mSv in the fourth monitoring cycle in Chongqing,including 18 in interventional radiology,and nine were abnormal due to the increase of workload during wearing.ln the same period,there were 130 person-times of ocular lens dose monitoring of interventional personnel,including four person-times of estimated annual dose exceeding 20 mSv and personal dose exceeding 1.25 mSv.The chromosomal aberration analysis were carried out for those with abnormal ocular lens dose and individual dose,two people had dicentric(1),one had triadial(1),and one was normal.Conclusion The abnormal results of individual dose monitoring of interventional radiation workers in Chongqing cannot to be ignored,and it is necessary to strengthen the occupational health monitoring of radiation workers,improve the investigation of abnormal personal dose monitoring,popularize dose monitoring in key parts,and improve the occupational health examination items of radiation workers,and improve the occupational protection.
