摘　　要：目的通过分析2016年石家庄辖区内医用辐射类放射工作人员的外照射个人剂量数据,发现个人剂量监测中存在的问题,提出进一步规范放射工作人员个人剂量计佩戴的相关建议。方法根据GBZ 128-2016《职业性外照射个人监测规范》的办法,采用Li F(Mg,Cu,P)热释光剂量计,对2016年委托石家庄市职业病防治院进行个人剂量监测的放射工作人员进行外照射个人剂量水平监测,对采集的数据进行处理和统计分析。结果 2016年共监测医用辐射类类放射工作人员3 749人,有效监测率为63%。人均年剂量当量为1. 55(m Sv/a),其中核医学放射工作人员人均年剂量当量最高为1. 82 m Sv/a,不同工种有效剂量95%置信区间部分存在交叉重叠,计算的相对扩展不确定度均在14%左右,利用SPSS进行组间比较,差异有统计学意义(P <0. 01)。结论 2016年石家庄市医用辐射类工作人员个人剂量基本符合要求,但核医学及介入放射学工作人员的个人剂量监测工作仍需加强。Objective Through analysis of external individual doses to radiation workers in medical system in Shijiazhuang in 2016,to find the problems in individual monitoring so as to provide related proposals to further standardize the wearing of personal dosimeters for radiation workers. Methods According to the requirements of the Specification for Individual Monitoring of Occupational External Radiation( GBZ 128-2016),the Li F( Mg,Cu,P) thermoluminescence dosimeter was used to monitor the external individual dose of radiation workers by Shijiazhuang Occupational Disease Prevention and Treatment Hospital,and relevant data in 2016 were collected and statistically analyzed. Results A total of 3749 radiation workers were monitored,and the effective monitoring rate was 63%. The per capita annual dose equivalent of 2362 radiation workers was 1. 55 m Sv/a,and the highest value of 1. 82 m Sv/a was found in nuclear medicine workers. There was overlap in the 95% confidence interval of the effective dose for different types of radiation workers,the relative expanded uncertainty were all around14%,and the difference of individual dose was statistically significant among different working types( P < 0. 01). Conclusion The level of individual dose for radiation workers in medical system in Shijiazhuang City in 2016 basically met the requirements of national standard. However,the individual monitoring should be further strengthened for the nuclear medicine and interventional radiology staff.
