Abstract Objective To ascertain the levels and distributions of individual dose of radiologic workers arising from external exposure in medical institutions in Yangpu District during 2018—2020, so as to provide basic data for the prevention of occupational radiation diseases.Methods Based on the individual dose monitoring specifications for occupational external exposure, the individual dose of radiologic workers was monitored by the thermoluminescence dosimetry systems, and the data were collected and analyzed.Results A total of 2082 people were monitored from 2018 to 2020, and the average annual effective dose per capital was 0.20 mSv·a−1. The average annual effective dose per capital in 2020 was lower than that in 2018 and 2019, and the difference was statistically significant (P < 0.05). The average annual effective dose of 4 radiologic workers exceeded 5 mSv·a−1 per capital. The average annual effective dose of diagnostic radiology was 0.20 mSv·a−1, which was higher than that of dental radiology and other medical applications, and the difference was statistically significant (P < 0.05). The average annual effective dose per capital of nuclear medicine was 0.34 mSv·a−1, which was higher than that of other medical categories, and the difference was statistically significant (P < 0.05). The average annual effective dose per capital in unrated hospitals was 0.14 mSv·a−1, which was lower than that in tertiary hospitals and secondary hospitals, and the difference was statistically significant (P < 0.05).Conclusion The average annual effective dose per capital of radiologic workers in medical institutions in Yangpu District is generally kept at a low level. The radiation protection of radiologic workers in nuclear medicine, secondary and tertiary hospitals should be strengthened to reduce the occupational external exposure doses to the lowest level as possible.
