Abstract: To better enhance personal protection awareness of radiation workers and their attention to personal dose monitoring, the external exposure personal dose monitoring data of radiation workers in a certain class—A traditional chinese medicine hospital from january 2021 to december 2024 were analyzed to evaluate the dose differences among different years, working positions, and professional categories. A total of 299 person-times were monitored over four years, with an average annual effective dose of 0.17 mSv/a. There were significant dose differences among different years (P<0.05), with the highest dose in 2021. The dose differences between interventional group and radiological diagnosis group in the nursing position, and between technicians and nurses in radiological diagnosis group were significant (P<0.05). The dose differences between interventional group in the oncology department and those in the cardiovascular department, neurosurgery department, and endoscopy center were significant (P<0.05). There were no significant dose differences between various radiation positions and different professional categories. The results suggest that the annual effective dose of radiation workers in this class-A traditional chinese medicine hospital comply with national standards. It is necessary to continuously strengthen occupational protection training and the promotion of relevant regulations, strictly supervise protective measures in workplace, and ensure occupational health.
