Analysis of some blood indexes of interventional radiation workers

Objective: To understand the health status and countermeasure of interventional radiation workers in a hospital, and detect signs of health damage promptly, and prevent the occurrence and development of occupational radiation disease. Methods: A total of 156 interventional radiation workers in five hospitals were selected as the intervention group. The intervention group was divided into three groups according to the working ages: ≤ 10, 10 ∼ 20, ≥ 20 years, and 134 workers who were not engaged in radiation work were selected as the control group. The chromosomal aberration (CA) rate, antioxidant function and peripheral blood cells were compared between the control group and the intervention group, different groups. Results: The detection of chromosomal aberration rate in lymphocytes of intervention group was higher than that of control group, with statistically significant (P < 0.05); The CA rate in lymphocytes of groups with different working ages increased with the increase of working ages, which is statistically significant (P < 0.05). SOD and GSH in intervention group was lower than that of the control group, with statistically significant (P < 0.05). MDA was higher than that of the control group, but there was no significant difference (P > 0.05); and there was no significant difference in SOD, GSH and MDA between different working ages groups (P > 0.05). The abnormal rate of WBC, HGB in intervention group was higher than that of the control group, and the abnormal rate of WBC and HGB was statistically significant (P < 0.05). The abnormal rate of WBC of groups with different working ages increased with the increase of working ages and it had significant difference (P < 0.05). Conclusion: Low dose ionizing radiation have an impact on interventional radiologists in some blood indexes, we should strengthen the radiation protection work of intervention radiation and carry out occupational health examination regularly.
