Abstract:
Objective To analyze the health effects of long-term occupational exposure to ionizing radiation on radiation workers in a nuclear power plant, and to provide a scientific basis for their occupational health monitoring. Methods In 2023, 183 radiation workers in a nuclear power plant were subjected to the analysis of blood cell parameters such as mean red blood cell count, white blood cell count (WBC), lymphocyte count, and hemoglobin count, thyroid function indicators such as serum triiodothyronine, thyroxine, and thyrotropin, as well as the chromosomal aberration rate and micronucleus rate of the lymphocytes in the peripheral blood. Results The blood cell parameters, thyroid function indicators, chromosomal aberration rate, and micronucleus rate of these radiation workers in the nuclear power plant were within normal reference ranges. Comparison among radiation workers with different ages showed statistically significant differences in triiodothyronine (H = 6.98, P < 0.05) and micronucleus rate (H = 48.44, P < 0.05). Among the three groups of radiation workers with different working years, WBC was significantly different (χ2 = 3.87, P < 0.05), with the lowest WBC observed in radiation workers with ≥ 20 years of service. Thyroxine (χ2 = 4.01, P < 0.05) and micronucleus rate (H = 40.95, P < 0.05) also varied significantly among these three groups. Conclusion Thyroid triiodothyronine level and micronucleus rate were affected by age, while WBC, thyroid thyroxine level, and micronucleus rate were related to working years. Targeted health management should be carried out for radiation workers in nuclear power plants to improve the awareness of radiation protection and continuously enhance their health status.
