Objective To evaluate the control effect of occupational hazards in a digital radiography （DR） imaging diagnosis construction project, so as to ensure the health and safety of radiation workers and the public. Methods For DR room in a university hospital, the on-site radiation hygienic investigation and on-site inspections were performed ac- cording to the Specifications for compilation of occupational hazard evaluation report in radiological protection on construc- tion project （GBZ/T 181-2006）, the Hygiene inspection regulations for radiological diagnosis and treatment construction projects and three principles of radiation protection. Results The DR machine application quality and surrounding radi- ation levels of the DR room were in accordance with the national standards. The room protection design, room shielding protection, personal protective equipment, and safety measures were reasonable and effective. Conclusion The DR imaging diagnosis construction project belongs to the general category of radiological hazards, and the radiation protection and safety facilities in the normal operation can effectively prevent the radiation workers and surrounding public.
