Abstract

Two new participations in the BIPM.RI(II)-K1.Cr-51 comparison have been added to the previous results and this has produced a revised value for the key comparison reference value (KCRV), calculated using the power-moderated weighted mean. A link has been made to the EURAMET.RI(II)-K2.Cr-51 comparison piloted by the POLATOM in 2022, who sent an ampoule from the EURAMET comparison to the International Reference System (SIR). The LNE-LNHB (France) used the EURAMET comparison to update its degree of equivalence. The degrees of equivalence between each equivalent activity measured in the SIR and the KCRV have been calculated and the results are given in the form of a table for the latest results in the BIPM.RI(II)-K1.Cr-51, and the linked EURAMET.RI(II)-K2.Cr-51. A graphical presentation is also given. To reach the main text of this paper, click on Final Report. 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).

更新BIPM.RI(II)-K1.Cr-51放射性核素51Cr放射性活度测量的比对BIPM.RI(II)-K1.Cr-51，纳入KRISS（韩国）2012年的结果和POLATOM（波兰）2022年的结果，并与2022年EURAMET.RI(II)-K2.Cr-51比对相联系

BIPM.RI(II)-K1.Cr-51 比对中的两个新参与方已被添加到之前的结果中，这就产生了使用功率调制加权平均值计算的关键比对参考值（KCRV）的修订值。与 POLATOM 于 2022 年试行的 EURAMET.RI(II)-K2.Cr-51 比较建立了链接，POLATOM 将 EURAMET 比较中的一个安瓿发送到国际参考系统 (SIR)。LNE-LNHB （法国）利用 EURAMET 比对更新其等效度。在 SIR 和 KCRV 中测量的每种等效放射性活度之间的等效度已经计算出来，其结果以表格的形式在 BIPM.RI(II)-K1.Cr-51 和链接的 EURAMET.RI(II)-K2.Cr-51 中给出了最新结果。本文还提供了图表说明。要阅读本文正文，请点击最终报告。请注意，本文是 BIPM 关键对比数据库 https://www.bipm.org/kcdb/ 附录 B 中的文本。根据 CIPM 互认安排 (CIPM MRA) 的规定，最终报告已通过同行评审，并批准由 CCRI 出版。

期刊介绍： Published 6 times per year, Metrologia covers the fundamentals of measurements, particularly those dealing with the seven base units of the International System of Units (metre, kilogram, second, ampere, kelvin, candela, mole) or proposals to replace them. The journal also publishes papers that contribute to the solution of difficult measurement problems and improve the accuracy of derived units and constants that are of fundamental importance to physics. In addition to regular papers, the journal publishes review articles, issues devoted to single topics of timely interest and occasional conference proceedings. Letters to the Editor and Short Communications (generally three pages or less) are also considered.
