| 目的 分析医疗机构放射工作人员个人剂量监测异常结果,为规范医疗机构放射工作人员个人剂量管理工作提供依据。方法 通过全国放射卫生信息平台的职业性放射性疾病监测子系统,收集2020-2022年度河南省18个省辖市168家医疗机构410名放射工作人员516个单个监测周期个人剂量监测异常结果,对异常结果涉及放射工作人员的性别、年龄、工龄、职业类别、所在医疗机构级别、剂量计佩戴是否规范等情况进行分组,分析个人剂量监测结果影响因素。结果 2020-2022年度河南省医疗机构放射工作人员个人剂量监测异常结果发生率分别为6.83×10-3、5.22×10-3、6.30×10-3。异常结果主要分布于男性放射工作人员(占66.83%)、诊断放射学(59.51%)和介入放射学(34.63%)相关岗位、三级(54.39%)和二级医疗机构(36.34%)。不规范佩戴剂量计和规范佩戴剂量计情况下,不同级别医疗机构和不同职业类别之间异常结果发生率的差异均有统计学意义(χ2=14.42、6.56、32.96、177.15,P<0.05))。因工作量增加导致"受照剂量异常"的放射工作人员年个人剂量中位数为3.95 mSv,介入放射学工作人员年个人剂量高于放射治疗学工作人员(4.45、2.91 mSv,Z=5.07,P<0.05)。结论 应加强放射工作人员放射防护教育和培训,规范个人剂量计佩戴;重点关注介入放射学工作人员的职业照射,采取有效措施降低其受照剂量。 |

| Objective To analyze the abnormal dose monitoring result of radiation staff in medical institutions and provide a basis for standardizing the personal dose management of radiation staff in medical institutions. Methods Through the occupational radiation disease monitoring subsystem of the National Radiation Health Information Platform, 516 individual dose monitoring abnormal result of 410 radiation workers in a single monitoring period,which in 168 medical institutions under the 18 cities in Henan province were collected from 2020 to 2022 as research objects. Based on gender, age, length of service, occupational category, medical institution level, whether the dosimeter wearing standard, the abnormal result of radiation workers were grouped to analyze the influencing factors of individual dose monitoring result. Results The incidence of abnormal individual dose monitoring result in 2020-2022 was 6.83 × 10-3, 5.22 × 10-3 and 6.30 × 10-3, respectively. Abnormal results were mainly distributed in male radiology workers (66.83%), diagnostic radiology (59.51%) and interventional radiology (34.63%), tertiary (54.39%) and secondary medical institutions (36.34%). In the case of wearing personal dosimeter in a standard or irregular way,there were statistically significant differences in the incidence of abnormal outcomes between different levels of medical institutions and different occupational categories(χ2=14.42, 6.56, 32.96, 177.15, P<0.05).The median annual individual dose of radiology workers with " abnormal exposure dose" due to increased workload was 3.95 mSv, and the annual individual dose of interventional radiology workers was higher than that of radiotherapeutic workers (Z=5.07, P<0.05). Conclusions The education and training of radiological protection should be strengthened, and the wearing of individual dosimeters should be standardized; focus on the occupational exposure of interventional radiology staff, and take effective measures to reduce their exposure dose. |
