Abstract:
Objective To understand the individual dose monitoring of occupational external exposure for radiation workers in Wuhan City and analyze the dose change trend, and to provide a scientific basis for radiation protection management of radiation workers. Methods The data on the monitoring results of occupational external exposure of radiation workers in Wuhan City from 2017 to 2021 were collected through the National Personal Dose Registration System, and the individual dose levels of different years, different occupational categories, and different levels of hospitals were analyzed. Results A total of 9 134 radiation workers were investigated, with an average annual effective dose per capita of 0.20 mSv/a. The overall personal annual effective dose from 2017 to 2021 showed a decreasing trend (P<0.001). The per capita annual effective dose in medical applications was higher than that in industrial applications (0.22 mSv vs 0.14 mSv; P<0.001). Among medical applications, diagnostic radiologists had the highest average annual effective dose (0.27 mSv), and among industrial applications, industrial irradiators had the highest average annual effective dose (0.29 mSv). The proportion of personnel with personal annual effective doses exceeding 1 mSv was higher in interventional radiology and industrial nondestructive testing (4.90% and 1.90%). The annual effective dose per capita in Class I and unrated hospitals was higher (0.35 mSv). Conclusion The average annual effective dose of radiation workers in Wuhan City has decreased year by year and has not exceeded the national standard limit (20 mSv). Radiation protection management still needs to focus on personnel with personal annual effective doses exceeding 1mSv in interventional radiology and industrial nondestructive testing, and supervision over primary healthcare institutions and industrial radiation should be strengthened.
