@@@@Objective To verify the effect of radiation protection of a PET-CT Center which has a dual channel and single flow design, reduce radiation damage to the working personnel and the subjects. Methods According to the correlative criterion and literature, detect the radioactivity level of the PET-CT center by using multifunctional radiometers, validation the radiation protection effect. Results The design of the PET-CT center is reasonable, surface contamination of each workplace is in line with national standards, the annual radiological dose of the working personnel are less than 2 mSv. Conclusions the design of the dual channel and single flow is helpful, the radiation environment is safe when the PET-CT is during the normal operation.
