摘要: 目的 分析2017—2021年济宁市某医疗机构放射工作人员个人剂量监测水平,为针对性开展放射人员健康教育提供支持。方法 采用热释光设备监测放射工作人员职业性外照射个人剂量,以2017—2021年济宁市某放射诊疗机构放射工作人员为调查对象,分析连续5年个人监测剂量结果。结果 2017—2021年共监测放射工作人员1 685人次,全部放射工作人员年集体有效剂量为1 608.12人·mSv,人均年有效剂量为0.95 mSv。不存在个人年有效剂量超过5 mSv/a的人员。不同年份个人年有效剂量比较,差异有统计学意义(H=42.168,P<0.01)。2021年个人年有效剂量最高,为1.70 mSv。≥5年工龄组高于<5年工龄组,10~<20和≥20年工龄组高于5~<10年工龄组,差异均有统计学意义(均P<0.01);不同职业类别个人年有效剂量比较,差异有统计学意义(H=187.603,P<0.01)。核医学人员个人年有效剂量最高,为1.06 mSv。结论 2017—2021年济宁市某医疗机构放射工作人员个人剂量处于低水平,在放射防护管理上应重点关注核医学、年龄≥50岁和工龄≥5年的放射工作人员。对于介入放射人员,建议结合实际情况进行眼晶体剂量监测。对于核医学人员尤其接触131I人员,建议增加内照射监测从而更加准确评估个人剂量。

Abstract: Objective To analyze the individual dose monitoring level of radiologists in a medical institution of Jining City from 2017-2021,provide support for targeted health education for radiation personnel. Methods The thermoluminescence dose equipment was used to monitor the individual dose of occupational external exposure of radiation workers. The radiation workers in a medical institution of Jining City from 2017-2021 were selected as the survey objects,to analyze the individual dose monitoring results in five consecutive years. Results From 2017 to 2021,totally 1 685 radiation workers were monitored,and the annual collective effective dose of all radiation workers was 1 608.12 mSv,the annual effective dose per capita was 0.95 mSv. There was no person whose annual effective dose per capita exceeded 5 mSv/a. There was statistically significant difference in annual effective dose per capita among different years(H=4.168,P<0.01). The individual annual effective dose in 2021 was the highest,which was 1.70 mSv. The individual annual effective dose in ≥5 years of working age group was higher than that in <5 years of working age group,while the individual annual effective dose in 10-<20 and ≥20 years of working age groups was higher than that in 5-<10 years of working age group,and the differences were statistically significant(P<0.01). There was statistically significant difference in the individual annual effective dose among different occupational categories(H=187.603,P<0.01). The individual annual effective dose of nuclear medicine workers was the highest(1.06 msv). Conclusions From 2017 to 2021,the personal dose of radiation workers in a medical institution of Jining City is at lower level,and and the management of radiation protection should focus on nuclear medicine,the age group ≥50 years old and ≥5 years of working age group. For interventional radiologists,it is recommended that the ophthalmic lens dose monitoring should be carried out in combination with the actual situation. For nuclear medicine personnel,especially who is exposed to 131I,it is recommended that the internal exposure monitoring should be taken to more accurately evaluate personal dose.
