title: Renewing the radiopharmaceutical accuracy check service for Canadian radionuclide calibrators.
abstract: From 1986 to 2000, a fraction of the Canadian nuclear medicine community participated in a service offered by the National Research Council (NRC) of Canada to check the accuracy of administered doses of radiopharmaceuticals. The NRC renewed this service in recent years with a revalidation and reviving of the Secondary Standard Ionizing Radiation Chamber System (SSIRCS). The NRC conducted mock services for (99m)Tc, in varying geometries (syringes and serum vials), on two NRC commercial radionuclide calibrators, and at a nuclear medicine department in Canada. These tests showed the measured doses to be within 10% of the prepared standard but in some cases were sufficiently different from unity to warrant specific geometry factors to be derived.
