Abstract: Objective To analyze the identification of major abnormal results in occupational health examinations for radiation workers, and provide a basis for scientific protection for radiation workers. Methods Physical examination data of radiation workers who participated in pre-employment and on-the-job radiation occupational health examinations at our hospital from January 2018 to December 2022 were collected, and the identification of major abnormal results and suspected occupational diseases in their radiation occupational health examinations were retrospectively analyzed. Results A total of 28 055 physical examination data were collected, among them 365 people (1.30%) were detected with major abnormal results. Within the 365 people, 175 people (47.95%) with abnormal blood routine, 108 people (29.59%) with severe visual impairment, 75 people (20.54%) with severe thyroid disease, and 20 people (5.48%) with lens opacity; Two individuals were suspected of having occupational radiation-induced cataracts. There was no statistically significant difference in the detection rate of major abnormalities in blood routine, thyroid, and lens between males and females during their employment; Except for 2020, there was a statistically significant difference in the detection rate of major abnormal physical examination results among different age groups during their employment, with the highest detection rate in the age group of ≥50 years old; There is no statistically significant difference in the detection rate of major abnormal results during physical examinations for employees with different radiation work experience. Conclusion Attention should be paid to the occupational health examination of radiation workers, especially the occupational health status of pre-employment, elderly, and high seniority personnel. Early intervention should be carried out for personnel who are not suitable for radiation work to effectively ensure the occupational health and safety of radiation workers.
