Radionuclide calibrator measurements of 18F in a 3 ml plastic syringe

This paper discusses the calibration of Capintec radionuclide calibrators for the measurement of 18F in the pharmacy and clinic. In support of a planned regional comparison, a secondary laboratory was set up at Oak Ridge National Laboratories in Oak Ridge, TN. The laboratory was used to prepare 1 mL 18F-fluorodeoxyglucose sources in 3 mL plastic BD syringes (Becton, Dickinson and Company, Franklin Lakes, New Jersey, USA) and to determine dial settings in three models of radionuclide calibrators. Measurements were verified by comparing radionuclide calibrator measurements of a 5 mL ampoule source with previous results. The CIEMAT/NIST method of tritium efficiency tracing was used for activity determinations.
