Occupational health status about radiation workers from township hospitals in Gansu, China

Abstract

Objective: To investigate occupational health status about radiation workers from township hospitals in Gansu, China, and to explore the dose-effect relationship of exposure dose of radiation workers. Methods: A total of 390 X-ray workers from township hospitals in Gansu Province and 450 X-ray workers from the county/district-level hospitals in the county/district where the township hospitals were located were divided into research group and control group. Their workload, radiation protection condition, and occupational health monitoring data were used for impact assessment and risk estimation. Results: The annual workload of radiation workers from township hospitals was 845.33±361.622 people, and that of radiation workers from county/district-level hospitals was 1967.74±762.055 people; there was a significant difference in annual workload between the two groups of subjects (P<0.05) . Indices such as detection rate of lens opacity, detection rate of abnormal platelet count, red blood cell count, and hemoglobin count, micronucleated lymphocyte rate, and chromosome aberration rate were significantly different between the two groups (P<0.05) . Conclusion: Radiation workers from township hospitals suffer from certain radiation damage.
