Web31. aug 2015 · Shielding for positron emission tomography (PET)/CT suites is now addressed. Purpose This book is a compendium providing the information needed for physicists to specify shielding for diagnostic facilities in the UK. Webhealth risks [4]. During PET-CT shielding calculation, the factors re taken into a account are source of radiation, amount of activity, decay of activity, number of patient per day, distance, shielding material and occupancy factor etc. A lot of methods have been developed in this calculation but in all cases above factors are considered.
