Show affiliationsSince 1976, twelve national metrology institutes (NMIs) have submitted 29 samples of known activity of 22Na to the International Reference System (SIR) for activity comparison at the Bureau International des Poids et Mesures (BIPM). The activities ranged from about 300 kBq to 20 MBq. The degrees of equivalence between each equivalent activity measured in the SIR and the key comparison reference value (KCRV) have been calculated and the results are given in the form of a matrix for nine NMIs. A graphical presentation is also given of this BIPM.RI(II)-K1.Na-22 comparison.
