Abstract: Objective To analyze the health monitoring data and personal dose monitoring data of 843 radiational workers in order to provide a reference for further work on radiological protection. Methods A total of 843 radiological staffs in Baoding from 2016 to 2017 were selected as our subjects. Their occupational health examination data and personal dose monitoring data were collected, meanwhile, four sensitive indicators including blood routine, eye lens condition, thyroid function and chromosome aberration were detected too. Data were analyzed with software SPSS 17.0. Results The abnormal rate of routine blood test indexes of female workers was higher than that in male workers(P=0.014). As the increase work history, the abnormal rate of occupational health(P=0.002)and the five abnormal rates of thyroid function were also increased(P=0.024). The difference was statistically significant. The rate of lens turbidity of worker with the group 1-5 mSv was higher than that in worker with group MDL-<1 mSv, and there was statistically significant difference between these. The chromosomal aberration rates of workers engaged in nuclear medicine(P=0.040)and interventional radiology(P=0.012)were all higher than that of workers engaged in radiation diagnosis, and there was statistically significant difference between these workers. Conclusion Long-term and low dose radiation exposure has certainly affected the health of radiation workers. The radiation workers who are female, long exposure history and engaged in interventional radiology or nuclear medicine can be impacted easily.
