Abstract
Since 2000, 8 laboratories have submitted 10 samples of 177Lu to the International Reference System (SIR) for activity comparison at the Bureau International des Poids et Mesures (BIPM), with comparison identifier BIPM.RI(II)-K1.Lu-177. Recently, the LNE-LNHB (France) and the IRA (Switzerland) participated in the comparison and the key comparison reference value (KCRV) has been updated. The degrees of equivalence between each equivalent activity measured in the SIR or linked to the SIR from the CCRI(II)-K2.Lu-177 comparison and the updated KCRV have been calculated and the results are given in the form of a table. A graphical representation is also given.
Note that this text is that which appears in Appendix B of the BIPM key comparison database https://www.bipm.org/kcdb/.
The final report has been peer-reviewed and approved for publication by the CCRI, according to the provisions of the CIPM Mutual Recognition Arrangement (CIPM MRA).
