Development of the national radionuclide dose calibrator standardisation service

The Australian Nuclear Science and Technology Organisation, acting as agent for the CSIRO Division of Applied Physics, maintains the Australian standard of measurement for activity. The standard includes all nuclear medicine gamma emitters and a new standard for pure positron emitters. Under Section 10 of the National Measurement Act 1960, if a measurement is made for a legal purpose, or if the legality of a measurement is in dispute, it can only be confirmed if the following two conditions are fulfilled: (a) that the measurement be in terms of the prescribed Australian legal units of measurement. (b) that it can be proven to be traceable to an Australian primary standard of measurement. To satisfy these requirements, radionuclide dose calibrators require a calibration report determined by Ansto. For this reason, Ansto has developed the national radionuclide dose calibrator standardisation service.
