Abstract
<p> Purpose: The aim of this study was to investigate the leakage radiation dose rate on the surface of an auto infusion device in 18F-fludeoxyglucose (FDG) positron emission tomography. Method: We preliminary measured the radioactivity of delivery-supplied FDG drugs. Leakage radiation doses on the six (front, rear, right, left, top, and bottom) surface points of the auto infusion device were measured ninety minutes before the assay time using an energy-compensated gamma scintillation survey meter and an ionization chamber-type survey meter. Result: Leakage radiation doses on the front, rear, right, left, and top surfaces were less than 7 µSv/h and satisfied specification of the auto infusion device. However, a leakage dose exceeding 40 µSv/h was detected on the bottom surface.</p>
