Abstract:
Objective To investigate the occupational health status of the radiation workers in Xiamen, China, and provide direction and basis for improvement of occupational health surveillance. Methods After excluding duplicate records, a total of 7000 individuals who underwent occupational health examinations due to radiation exposure in Xiamen City from 2022 to 2023 were selected. Among them, 2499 individuals underwent examinations before employment, 4090 during employment, and 411 at the time of job separation. The results were analyzed. Results A total of 6979 (99.7%) individuals were deemed fit to engage (or continue engaging) in radiation work or to leave the position, while 21 (0.3%) individuals were found unfit. In the routine medical examinations of different genders, the items with relatively high abnormal rates included overweight and obesity (35.22%, χ2 = 43.29, P < 0.01), abnormal liver function (33.74%, χ2 = 153.53, P < 0.01), abnormal renal function (25.83%, χ2 = 195.22, P < 0.01), and hyperuricemia (24.53%, χ2 = 267.78, P < 0.01). For all of these items, the abnormality rates were significantly higher in males than in females. The abnormal rates of examination items related to radiation hazard factors were generally higher for females than for males. Statistically significant gender differences were observed in lens abnormality rate (χ2 = 11.38, P < 0.001), the decrease rate of white blood cells (χ2 = 12.04, P < 0.001), the abnormal rate of red blood cells (χ2 = 25.47, P < 0.01), the abnormal rate of platelets (χ2 = 88.07, P < 0.01), and the micronucleus rate of peripheral blood lymphocytes (χ2 = 6.98，P = 0.008). The difference in micronucleus rate of peripheral blood lymphocytes among groups with different years of radiation exposure was statistically significant, and the rate increased with increasing exposure years. Conclusion Long-term exposure to radiation has a certain impact on the health of radiation workers. Radiation workers should enhance radiation protection measures, increase the awareness of protection, and reduce radiation-related damage.
