Objective This paper tries to study and analyze the radiation protection and control effect of CT indoor radiation workers, so as to effectively ensure the health and safety of staff and the masses in the radiation range. Methods Field interpolation was conducted to identify the most important occupational hazard of staff in the CT diagnostic project was X-ray.Results Test of the CT machine room of 1m from the roof, 0.3 m from the north wall, 0.3 m from the south wall, 0.3 m from the east wall, 0.3 m from the west wall, from the operation bit, 0.3 m from the lead observation room, from the operation room, 0.3 m from the outside, 0.3 m outside from the door, 0.3 m outside the door stitch of the machine room, the results were all qualified. Conclusion Comprehensive evaluation of radiation protection is that the hospital CT room Radiological Protection office is in line with the relevant state regulations and standards for radiological health requirements, the staff work under effective radiological protection.
