| 目的 调查与分析我国2019-2021年介入放射工作人员眼晶状体剂量水平。方法 通过国家放射卫生信息平台，收集我国31个省、直辖市、自治区2019-2021年介入放射工作人员的眼晶状体剂量监测数据。眼晶状体剂量评价指标为个人剂量当量Hp（3），每次监测周期不超过3个月。用Kusall-Wallis H检验比较不同年份、职业岗位、介入科室、工作所限的介入放射工作人员眼晶状体剂量分布的差异。结果 2019-2021年共调查6 643人次介入放射工作人员，平均眼晶状体年剂量为1.03 mSv，中位数为0.17 mSv，最大值为94.88 mSv，其中有59人次超过20 mSv。经分析发现，2019年、2020年医生眼晶状体年剂量水平略高于护士，差异有统计学意义（平均秩次差=118.29、129.71，P<0.01），2019年从事心脏介入的放射工作人员眼晶状体剂量水平高于从事周围血管介入的放射工作人员，差异有统计学意义（平均秩次差=46.52，P<0.05）。结论 介入放射工作人员眼晶状体剂量水平低于我国现行标准，但部分人员超过了国际最新推荐剂量限值，为保护介入放射工作人员职业健康，应加强对其眼晶状体剂量的监测。 |

| Objective To investigate and analyze the eye lens dose to interventional radiology workers in China from 2019 to 2021.Methods The monitoring data on eye lens dose to interventional radiology workers from 31 province-level units during 2019-2021 were collected through the National Radiological Health Information Platform. The eye lens dose evaluation indicator was Hp(3), with each monitoring period of no more than 3 months. Kusall-Wallis H test was used for the comparison of multiple groups and pairwise.Results A total of 6 643 interventional radiology workers were investigated from 2019 to 2021. The average annual eye lens dose was 1.03 mSv, with the median of 0.17 mSv and the maximum of 94.88 mSv. The annual eye lens dose to 59 workers exceeded 20 mSv. It was also found that the annual eye lens dose to the doctors in 2019 and 2020 was slightly higher than that to nurses (rank mean difference=118.29, 129.71, P<0.01), and the lens dose to interventional radiology workers who performed cardiac interventions in 2019 was higher than that to workers who performed peripheral vascular interventions (rank mean difference=46.52, P<0.05).Conclusions The lens dose to interventional radiology workers is lower than the limits given in Chinese national standard currently in effect, but exceed the latest internationally recommended limit for a few ones. In order to protect the occupational health of interventional radiology workers, the monitoring of lens dose should be strengthened. |
