Abstract: By analyzing the abnormal rate of occupational health examination results and further understanding their health status of radiation workers in Taizhou City, in order to provide a basis for health monitoring and risk assessment of radiation workers. This study selects data from 4 351 radiation workers in Taizhou City from October 2022 to September 2024 for investigation, the impact of different genders, working years, job types, and ages on the health of radiation workers are compared and analyzed. The results show that the abnormal detection rate of absolute lymphocyte count increases with working years (χ²=11.602, P<0.05). The abnormal rates of white blood cell count (7.3%) and FT3 (2.7%) in the nuclear fuel cycle group are higher than those in the medical application group and industrial application group (χ²=19.440, 22.370, both P<0.05). The abnormal rate of lymphocyte percentage in the industrial application group (6.9%) is higher than that in the nuclear fuel cycle group and medical application group (χ²=7.047, P<0.05). The abnormal detection rates of absolute lymphocyte count and FT3 in male radiation workers are higher than those in female workers (6.4%>3.2%, 1.7%>0.5%, χ²=18.467, 10.799, both P<0.05), while the abnormal detection rates of FT4 and TSH in female radiation workers are higher than those in male workers (1.0%>0.2%, 3.6%>1.6%, χ²=12.207, 15.582, P<0.05). Long-term low-dose ionizing radiation exposure has a certain impact on the occupational health of radiation workers in Taizhou City. Therefore, it is necessary to further strengthen the awareness of radiation protection among radiation workers to further protect their occupational health.

Key words: low-dose ionizing radiation, radiation workers, occupational health examination
