| 目的 分析2018—2020年陕西省部分医院介入放射学工作人员眼晶状体剂量水平，掌握介入放射学工作人员眼晶状体剂量水平现状。方法 抽取陕西省三级以上医院3家，2018—2020年连续3年采用热释光剂量计对介入放射工作人员眼晶状体剂量进行监测，共监测152人次，监测周期3个月，分析不同性别、岗位及科室介入放射学工作人员眼晶状体个人剂量当量水平，以及2018—2020年介入放射学工作人员眼晶状体个人剂量当量水平的影响因素。结果 3年人均年当量剂量水平差异具有统计学意义（χ2=29.15，P<0.05），2018—2020年人均年当量剂量具有下降趋势；3年介入放射学工作人员眼晶状体个人剂量当量人数分布可以看出主要分布在最低可探测水平（MDL）~5.0 mSv之间，比例为69.08%；不同岗位、不同科室人均年当量剂量差异具有统计学意义（H=18.44、22.55，P<0.05），其中医生人均年当量剂量水平均高于护士、技师（Z=-3.36、-3.02，P<0.05），其中心血管内科人均年当量剂量水平高于其他科室，差异具有统计学意义（Z=-2.58、-3.76、-3.40，P<0.05）。logistics回归分析显示，从事放射工作时间、岗位、常规个人剂量、工作量及曝光时间为影响人均年当量剂量影响因素。结论 陕西省介入放射学工作人员眼晶状体年当量剂量符合国家限值标准，但是有部分放射工作人员年剂量具有正常高值，需要加强持续对介入放射工作人员眼晶状体剂量的检测，并且针对从事放射工作时间、岗位、常规个人剂量、工作量及曝光时间调整工作人员工作内容，有效降低眼晶状体剂量水平。 |

| Objective To analyze and learn about the dose to the lens of the eye of interventional radiology workers in some hospitals in shaanxi province from 2018 to 2020.Methods From 2018 to 2020, three tertiary hospitals in shaanxi province were selected to monitor the dose to the lens of the eye of interventional radiology workers for three consecutive years. Monitoring was made for 152 person times, lasting for a monitoring period of 3 months. Analysis and comparison were carried out of dose equivalents to the interventional radiology workers in terms of different sexes, positions and departments, together with associated influencing factors during the three years.Results The difference in equivalent dose between the three years is statistically significant (χ2=29.15, P < 0.05), and a downward trend in the average annual equivalent dose was found from 2018 to 2020. The number of interventional radiology workers who received doses to the lens of the eye mainly between MDL and 5.0 mSv accounted for 69.08%. The difference in the average annual equivalent dose in different positions and departments was statistically significant (H=18.44, 22.55, P < 0.05). The average annual equivalent dose to doctor was higher than for nurses and technicians (Z=-3.36, -3.02, P < 0.05). The average annual equivalent dose in cardiovascular medicine department was higher than in other departments, with statistically significant difference (Z=-2.58, -3.76, -3.40, P < 0.05). Logistics regression analysis showed that radiation working hours, positions, routine personal doses, workload and exposure time are the factors that affect the average annual equivalent dose.Conclusions The annual equivalent dose to the lens of the eye of interventional radiology workers in shaanxi province meets the relevant national standards. However, the annual dose to some radiological workers has a normal high value. Therefore, it is necessary to strengthen the continued monitoring of the dose to the lens of the eye of the interventional radiology workers, and adjust the types of work for the workers based on radiation work hours, position, routine personal dose, workload and exposure time, so as to effectively reduce the dose level of the eye lens. |
