| Zusammenfassung | In 1998, five national metrology institutes (NMI), an international laboratory and the Bureau des Poids et Mesures (BIPM) took part in a comparison of activity measurements of 237Np as part of the EUROMET project No. 416 comparison identifier EUROMET.RI(II)-K.2.Np-237. The nominal activity per mass of the 237Np solution distributed was 150 kBq g-1. The three ampoules received by the BIPM for this comparison were also measured in the International Reference System (SIR) for activity comparison at the BIPM (identifier BIPM.RI(II)-K.1Np-237). Two other participants to the EUROMET comparison also submitted ampoules of the same 237Np. The degrees of equivalence between each laboratory and the key comparison reference value (KCRV) have been calculated and the results are given in the form of a graph and matrix for the three SIR participants and four other NMIs from the EUROMET comparison. |
