EXPERIENCES OF 15 YEARS ON METROLOGICAL SUPERVISION OF RADIONUCLIDE CALIBRATORS USED IN NUCLEAR-MEDICINE

Pursuant to the Hungarian Law on Legal Metrology, activity measurement s in nuclear medicine can be made by verified measuring instruments on ly. OMH has carried out this legal metrological task of verification f or more than 15 years. This paper outlines the calibration results for 12 various radionuclides for more than fifty instruments in our progr am, experiences of the type approvals of about 10 radionuclide calibra tor models and that of the practical usage, the results of the analysi s of measurement errors and the human aspects of the measurements. In addition it reports on the bilateral cooperation in the past years bet ween OMH (Hungary) and BEV (Austria) in the field of metrological supe rvision of radionuclide calibrators.
