Abstract:
Objective:To analyze and understand the level of occupational external radiation personal dose of radiation workers in a hospital, and provide a reference for radiation protection.Methods:In May 2023, the personal dose monitoring data of all radiation workers in the hospital from 2018 to 2022 were collected, and their occupational external radiation exposure levels were analyzed and evaluated. All radiation workers were divided into radiation diagnosis, radiotherapy, interventional radiology, and nuclear medicine according to their occupational categories.Results:A total of 1626 person-times were monitored from 2018 to 2022, and the average annual effective dose per person (0.13-0.36 mSV) was lower than the national limit of 20 mSv. The average annual dose of nuclear medicine was the highest (0.36 mSv), and interventional radiology was lower (0.13 mSv). The average annual dose of individuals was the highest in 2020 (0.24 mSv) .Conclusion:The average annual effective dose per person of radiation workers in this hospital is lower than the national standard, and it is still necessary to strengthen the inspection of the wearing of personal dosimeters and the using of protective equipment for radiation workers.
