Abstract Objective To analyze the occupational health monitoring data of radiation workers in some radiology and treatment institutions in China from 2015 to 2017, providing scientific basis for prevention and control of occupational radioactive diseases.Methods According to the "National Radiological Health Information Platform-Occupational Health Monitoring Module", data on occupational health monitoring of radiation workers in some radiological clinics in the past three years were collected for statistical analysis.Results The personal dose monitoring rates of the radiation workers in the monitoring hospitals from 2015 to 2017 were 98.3%, 98.9%, and 98.7%, respectively; the occupational health examination rates were 95.5%, 94.8% and 95.7%, respectively. The ratio of radiation workers' chromosomal aberration of peripheral blood lymphocytes was decreased by 0.9%, 0.7% and 0.3%, respectively. The opacity of the posterior capsule of the eye was decreased by 8.6%, 7.7% and 7.9%, respectively. The abnormal rates of thyroid examinations increased by 18.8%, 21.1%, 22.1% per year.Conclusion In general, the level of occupational health monitoring of radiation workers in radiology clinics in China was remarkably improved in recent years, however the inspection and protection of the lens and thyroid gland are of additional concerns.
