title: Radioactivity measurement of 18F in 16 ml vials for calibration of radionuclide calibrators.
abstract: Fluorine-18 is obtained through the reaction (18)O(p, n)(18)F using a cyclotron that is situated in a hospital in Jakarta. Standardization of the (18)F solution is performed by gamma spectrometry using calibration sources of (152)Eu, (60)Co and (137)Cs that have traceability to the International System of units (SI). The activities in the 16 ml vials that were used for calibrating the radionuclide calibrators were between 1 and 2 GBq, with expanded uncertainties of 3.8%. The expanded uncertainty, at a coverage factor of k=2, on the derived calibration factor for the radionuclide calibrator was 6.6%.
