The 0. As a result, barrier shielding may be required in floors and ceilings as well as adjacent walls. Since the patient becomes the radioactive source after the radiopharmaceutical has been administered, one has to consider the entire time that the subject remains in the clinic. Information about the physical properties of the most commonly used clinical PET radionuclides is summarized, although the report primarily refers to fluorine Typical PET imaging protocols are reviewed and exposure rates from patients are estimated including self-attenuation by body tissues and physical decay of the radionuclide. Examples of barrier calculations are presented for controlled and noncontrolled areas. Shielding for adjacent rooms with scintillation cameras is also discussed. Tables and graphs of estimated transmission factors for lead, steel, and concrete at 0. Meeting the regulatory limits for uncontrolled areas can be an expensive proposition. Careful planning with the equipment vendor, facility architect, and a qualified medical physicist is necessary to produce a cost effective design while maintaining radiation safety standards.

Calculated shielding requirements may be conservative in some areas when assuming a static point source and absence of scanner self-shielding. Dosimeters were also placed at three positions in the ceiling along the axial length of the scanner. Each position contained three dosimeters covered with 0, 1. Dosimeters were switched out every month for a total collection period of 10 months. The dosimeter measurements were compared to TG estimates by dividing the measured dose by the TG calculated dose.
