Abstract:
Objective To explore the radiation of the interventional diagnosis and treatment devices in some hospital of Hubei province to the circumstances and staffs.Methods The radiation shielding in the radiological workplace of the hospital was analyzed,and an evaluation model system was established based on dose equivalent level so as to estimate the shielding thickness of DSA machine room and the exposure dose to the staff.Results The designed shielding thickness of DSA machine room roof was tower than the theoretical one,while the designed thicknesses of other shields were higher than the theoretical ones,and the theoretical values of the east wall and roof in the DSA machine room were all higher than the limits of the national standards.The exposure doses to different parts and annual effective dose were all lower than the national limits.Conclusion The allocation of DSA machine room has to be optimized,and the staff gains satisfactory protection against radiation.
