Radiation protection evaluation on the control effect of occupational hazards in medical imaging center project

Objective: To analyze and evaluate on the radiation protection and control effect of occupational disease hazard in a hospital medical imaging center project, to ensure the occupational health and safety of radiological workers, patients or subjects and the surrounding public. Methods: Using the methods of radiation hygiene investigation, radiation detection, personal dose monitoring, occupational health examination, statistics analysis, the radiation protection control effect, equipment safety device, radiation detection level, quality control inspection of radiation equipment and radiological health management of the hospital were analyzed and evaluated. Results: The radiological protection facilities and radiological health management measures of the hospital medical imaging center are basically in line with relevant national standards. The radiation level of the radiating equipment room was 0.13∼0.17 μSv/h. The effective dose of radiation workers was 0.10∼1.92 mSv, and the effective dose per year in 2016 was higher than that in 2015 (t = -2.27, P < 0.05). The test results of radiological equipment quality control are consistent with relevant standards. The number of personal protective articles can not meet the needs of patients in the radiation room. Conclusion: The medical imaging center of the hospital, which is required to be overhauled, will be able to ensure the occupational health and safety of radiation workers, patients or subjects and the surrounding public.
