摘要

正文自 1976 年以来，已有 20 个实验室向国际基准系统（SIR）提交了 59 个 57Co 样品，供国际计量局（BIPM）进行放射性活度比对，比对标识符为 BIPM.RI(II)-K1.Co-57。最近，奥地利 BEV 也参与了比对。通过 CCRI（II）-S6.Co-57 比对，计算了在 SIR 中测量的或与 SIR 相关联的每种等效活度之间的等效度，并以表格形式给出了结果。如需阅读本文正文，请点击 "最终报告"。请注意，本文为 BIPM 关键对比数据库附录 B 中的内容 https://www.bipm.org/kcdb/.The 根据 CIPM 互认安排 (CIPM MRA) 的规定，最终报告已经过同行评审，并获准由 CCRI 发布。

Update of the BIPM comparison BIPM.RI(II)-K1.Co-57 of activity measurements of the radionuclide 57Co to include the 2023 result of the BEV (Austria)

Main textSince 1976, 20 laboratories have submitted 59 samples of ⁵⁷Co 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.Co-57. Recently, the BEV (Austria) participated in the comparison. The degrees of equivalence between each equivalent activity measured in the SIR or linked to the SIR from the CCRI(II)-S6.Co-57 comparison have been calculated and the results are given in the form of a table. A graphical representation 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).

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.
