摘　　要：目的了解廊坊市不同级别医院的各类放射工作人员的医疗照射频度与外照射个人剂量,评估放射工作人员职业健康风险,为放射防护工作提供技术依据。方法对廊坊市6家不同级别医院2016年全部医疗照射频度、外照射个人剂量开展调查,对调查数据进行统计分析。结果 6家医院中,三级、二级、一级医院放射诊断人员医疗照射人均人次数分别为4 217、3 066、883;三级、二级医院介入放射人员医疗照射人均人次数分别为174、115;一家三级医院的放疗人员医疗照射人均人次数为30;各类放射人员全年有效剂量范围为0. 78～1. 29 m Sv;介入、放射治疗、牙科、放射诊断放射工作人员单次暴露有效剂量分别为0. 005 6～0. 011、0. 038、0. 001 3～0. 004 2、0. 000 27～0. 002 3 m Sv。结论从事介入、放射治疗的放射工作人员单次电离辐射暴露的健康损害风险远高于其他放射工作人员;应以介入、放射治疗人员和低级别医院为重点,加强放射防护工作。Objective To understand the medical exposure frequency of and individual external exposure dose of various radiologists in different level hospitals of Langfang city,so as to evaluate the occupational health risk of radiologists and to provide technical basis for radiation protection. Methods The all medical exposure frequency and the external exposure personal dose of radiologists in 6 different level hospitals of Langfang in 2016 were investigated and the data were statistically analyzed.Results Among all 6 hospitals,the average number of medical exposures per person of radiological diagnostics workers in the third,second and first level hospitals was 4217,3066,883 respectively. The number of medical exposures per person of the interventional radiologists of the third,second level hospitals was 174,115 respectively. The number of medical exposures per person for radiotherapy workers in the third level hospital was 30. The annual effective dose range of various kinds of radiologists was 0. 78 ~ 1. 29 m Sv. The effective doses of single exposure for interventional,radiotherapy,dental and diagnostic radiation workers were 0. 02 ~ 0. 039 m Sv,0. 038 m Sv,0. 0013 ~ 0. 0042 m Sv,0. 00027 ~ 0. 0023 m Sv respectively. Conclusion The health risk of single exposure to ionizing radiation for radiologists engaged in intervention and radiotherapy is much higher than that of other radiologists. The interventional and radiotherapy workers and low-level hospitals should be given more attention to strengthen radiation protection.
