摘要

正文介绍了 COOMET 对用于辐射防护和放射诊断的 X 射线质量的空气热玛国家测量标准进行补充比对的结果。来自 COOMET 组织和国际原子能机构的九个国家计量机构参加了 COOMET 第 641 号项目。BelGIM 作为试点实验室。比对参考值（CRV）是根据 PTB 和 VNIIM 的平均结果得出的。几乎所有参与者都获得了有效的结果，这些结果在 0.28%至 2.6%的比较相对标准不确定度范围内保持一致。一些参与者的结果不可接受。要阅读本文正文，请点击最终报告。请注意，本文是 BIPM 关键比对数据库附录 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 出版。

COOMET regional comparison of the national standards of air kerma for x-radiation qualities used for radiation protection and diagnostic radiology (COOMET.RI(I)-S3)

Main textThe results of the COOMET supplementary comparison of the national measurement standards of air kerma for x-radiation qualities used for radiation protection and diagnostic radiology are presented. Nine National Metrology Institutes from the COOMET organization and the International Atomic Energy Agency participated in this COOMET project no.641. The BelGIM acted as a pilot laboratory. The comparison reference value (CRV) was obtained as the mean result of the PTB and the VNIIM. Almost all participants obtained valid results which were consistent within the relative standard uncertainties of the comparison ranging from 0.28% to 2.6%. Some participants had unacceptable results.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.
