Since 1976, 13 laboratories have submitted 29 samples of 22 Na 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.Na-22. Recently, the LNE-LNHB (France) 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 and the updated KCRV have been calculated and the results are given in the form of a table. A graphical presentation is also given. == Main text To reach the main text of this paper, click on Final Report [https://www.bipm.org/utils/common/pdf/final_reports/RI/BIPM.RI(II)/BIPM.RI(II)-K1.Na-22_(2020).pdf] .

更新BIPM比较放射性核素22 Na的活度测量值的BIPM.RI（II）-K1.Na-22，其中包括2014年LNE-LNHB的结果（法国）

自1976年以来，已有13个实验室向国际参考系统（SPM）提交了29种22 Na的样品，用于在国际测定和测量局（BIPM）进行活性比较，其比较标识符为BIPM.RI（II）-K1.Na-22。 。最近，LNE-LNHB（法国）参加了比较，并且关键比较参考值（KCRV）已更新。已计算出在SIR中测量的每个等效活动与更新的KCRV之间的等效程度，并以表格形式给出结果。还给出了图形表示。==正文要访问本文的正文，请单击最终报告[https://www.bipm.org/utils/common/pdf/final_reports/RI/BIPM.RI(II)/BIPM.RI(II ）-K1.Na-22_（2020）.pdf]。注意，此文本显示在BIPM密钥比较数据库kcdb.bipm的附录B中。org / [http://kcdb.bipm.org/]。最终报告已通过同行评审并获得批准。
