Abstract:
Objective:To explore the influencing factors of whole blood cells and genetics of medical radiation workers, and provide technical support for improving occupational health management and strengthening radiation protection.Methods:In January 2022, a total of 4180 medical radiation workers who underwent occupational health examination in Gansu Provincial Center for Disease Control and Prevention from January 2020 to December 2021 were collected as the research objects, and the results of demographic characteristics, whole blood cells, chromosome aberrations, lymphocyte micronucleus and other results were collected. The whole blood cells and genetic abnormalities of different demographic characteristics of medical radiation workers were compared. And the influencing factors of whole blood cells and genetic abnormalities were analyzed by multivariate logistic regression.Results:The rates of hemoglobin (HGB), chromosome aberration and lymphocyte micronucleus abnormality were the highest in the nuclear medicine group, and the rate of white blood cell (WBC) abnormality in the radiotherapy group was higher than those in other occupational groups, the differences were statistically significant ( P<0.05). The abnormal rates of WBC, HGB and lymphocyte micronucleus in female radiation workers were significantly higher than those in male radiation workers ( P<0.001). The abnormal rates of HGB and lymphocyte micronucleus were statistically different among different working years and different age radiation workers ( P<0.001). And the abnormal rate of platelet (PLT) was statistically different among different working years radiation workers ( P<0.05). The abnormal rate of HGB in radiation workers of different hospital levels was statistically different ( P<0.001). Logistic regression analysis showed that the risk of abnormal WBC and HGB in females radiation workers were 3.048 times and 13.122 times of those in males, respectively ( P<0.001). The abnormal risks of WBC in the 6-20 working years group and >20 working years group were 1.517 times and 1.874 times of that in the ≤5 working years group, respectively ( P<0.05). The abnormal risk of PLT in the >20 working years group was 2.643 times of that in ≤5 working years group ( P<0.05). The abnormal risk of WBC in radiotherapy group and intervention group were 2.407 times and 1.341 times of that in general radiotherapy group, respectively ( P<0.05) . Conclusion:Ionizing radiation has different effects on the whole blood cells and genetic indexes of workers in the nuclear medicine, interventional group and radiotherapy group. The occupational health protection of female radiation workers should be paid attention to.
