Abstract:Objective To analyze the results of occupational health examinations for radiological workers and understand the impact of occupational exposure to ionizing radiation on their health. Methods Data from occupational health examinations in 2023 for radiation workers in a city were collected，including blood pressure，thyroid ultrasound，electrocardiogram and laboratory indicators such as complete blood count［white blood cells（WBC），platelets（PLT），red blood cells（RBC），hemoglobin（HGB），etc.］，blood biochemistry［alanine aminotransferase（ALT），aspartate aminotransferase（AST），total bilirubin，direct bilirubin，total protein，albumin，fasting blood glucose（FBG），creatinine，uric acid，etc.］，thyroid function［thyroid - stimulating hormone（TSH），triiodothyronine（T3），thyroxine（T4），free triiodothyronine（FT3），free thyroxine（FT4），etc.］，and other parameters. Results A total of 6 977 subjects were included，with 4 472 males and 2 505 females，aged 18 to 91（34.48 ± 9.99）years. Males had higher abnormaldetection rates than females in indicators including blood pressure，RBC，HGB，FBG，T4，T3，FT3，and electrocardiogram（P<0.01）. Females showed higher abnormal rates than males in thyroid ultrasound，WBC，PLT，and TSH，with significant differences（P<0.01）. The abnormal detection rates of blood pressure，thyroid ultrasound，FBG，and electrocardiogram increased with the increase of age and seniority（P<0.01）. There was a sharp increase in the abnormal detection rate in the "post-work health examination" group for these parameters. Conclusion Long - term exposure to ionizing radiation has certain side effects on the health of radiation workers. It is important to focus on radiation protection for these workers and pay attention to their occupational health monitoring and management.
