Abstract:
Objective To investigate the external radiation doses and occupational health examination data of radiation workers in medical institutions in Zhangjiagang City, China, explore the effects of long-term exposure to low-dose ionizing radiation on their health, and provide a reference for occupational health monitoring. Methods The radiation workers of medical institutions in Zhangjiagang City were selected as the research subjects. Their personal radiation doses and occupational health examination data were collected. A scale was used for mental health survey. The data were analyzed according to different clinical characteristic groups. Results During the 5-year period from 2019 to 2023, the average annual radiation dose received by radiation workers in medical institutions in Zhangjiagang City was 0.21 mSv/year. There were significant differences in the average annual radiation dose across these years and radiation workers with different occupations. The results of occupational health examinations showed significant difference in the total abnormal detection rate among these years (P < 0.01). There were significant differences in the abnormal rates of blood pressure, blood routine, and electrocardiogram across these years (P < 0.05). There were significant differences in the abnormal rate of routine blood test in radiation workers with different sexes, years of service, and radiation occupations (P < 0.01). There were significant differences in the abnormal rate of blood pressure in radiation workers with different sexes, ages, and years of service (P < 0.01). The mental health survey showed significant differences between the radiation and the non-radiation groups in terms of occupational stress, anxiety score, and depression score (P < 0.05). Conclusion Long-term low-dose ionizing radiation may have adverse effects on the physical and mental health of radiation workers, and it is necessary to strengthen the occupational health examination and radiation protection of radiation workers.
