Analysis on the health status of radiation workers in an international airport

Abstract

Objective: To understand the occupational health status of radiation workers at an international airport, and to provide basis and reference for relevant competent authorities to conduct scientific and effective occupational health monitoring. Methods: From July to August 2019, 246 radiation workers at an international airport were selected as the research subjects (observation group) , and their occupational health examination data were collected. At the same time, 210 radiation workers from a medical institution were selected as the control group. The occupational health examination results of the two groups were compared. And the differences in occupational health examination results of airport radiation workers among difference service age were analyzed. Results: Compared with the control group, the detection rates of ocular lens opacity (1.63%, 4/246) and abnormal blood glucose (4.07%, 10/246) in the observation group were lower, the detection rates of abnormal skin (11.79%, 29/246) , abnormal B-ultrasound of liver, gallbladder and spleen (75.61%, 186/246) and abnormal chest X-ray (5.28%, 13/246) were higher (P<0.05) . There were significant differences in the abnormal detection rates of skin, blood glucose, B-ultrasound of liver, gallbladder and spleen among airport radiation workers with different service age (P<0.05) . Abnormal chromosome of peripheral blood lymphocytes, abnormal chest X-ray were mainly distributed in the service age of ≥20 years. The abnormal rate of B-ultrasound of liver, gallbladder and spleen was higher in different working age groups. Conclusion: Long term low-dose irradiation will have a certain impact on the occupational health of airport radiation workers. The occupational health monitoring of relevant personnel should be strengthened to protect their occupational health.
