Abstract
The Consultative Committee for Ionizing Radiation (CCRI) has coordinated the development of a long-term strategy to support the international measurement system for radionuclide metrology. Supported by the Bureau International des Poids et Mesures (BIPM) and its associated institutional members, the CCRI strategy captures how an NMI/DI can demonstrate capability in radionuclide metrology with the support that is available through the CCRI and the BIPM. The CCRI strategy, specifically the aspects with direct impact on radionuclide metrology, is described. Various projects to ensure that the international measurement system for radioactivity can be sustained in the short and long term will also be outlined.
