Abstract
ObjectiveTo investigate and analyze the eye lens dose to interventional radiology workers in China from 2019 to 2021.
MethodsThe 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.
ResultsA 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).
ConclusionsThe 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.
