Abstract
ObjectiveToexplorethecalculationmethodofprotectiveshieldingforrelevantworkplacesof PET center. Methods According to national standards such as GB18871-2002, AAPM TG108 experience-based formula was used to calculate the shielding thicknesses which can meet the requirements of protective shielding of PET/CT room, PET/MRI room and waiting room after PET injection and the shielding calculation method of radiation source was used to calculate the shielding thickness of PET injection room. Then the calculation results of shielding thicknesses were compared with the design results of shielding thicknesses. ResuItsTherangesofshieldingthicknessesofPET/CTroom,PET/MRIroom,PETinjectionroom (thefume hoodisexcepted)andwaitingroomafterPETinjectionare 8~21mmPbequivalents, 8~21mmPbequivalents, 7~29mmPbequivalentsand 4~24mmPbequivalents,respectively.ConcIusionThedesignresultsofshielding thicknesses and the calculation results of shielding thicknesses can meet the requirements of national standards, which indicates that AAPM TG108 experience-based formula can be used in the calculation of protective shielding for relevant workplaces of PET center.关键词
