Since 1978, 10 laboratories have submitted 17 samples of 67Ga 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.Ga-67. The PTB (Germany) and the NIST (United States) participated in the comparison. The key comparison reference value (KCRV) has been re-calculated using the power-moderated weighted mean. 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. A graphical presentation is also given.

更新放射性核素 67Ga 活度测量的 BIPM 比较 BIPM.RI(II)-K1.Ga-67,包括 PTB(德国)的 2010 年结果和 NIST(美国)的 2010 年结果

自 1978 年以来,10 个实验室向国际参考系统 (SIR)提交了 17 个67 Ga样品,用于在国际测量与测量局 (BIPM) 进行活性比较,比较标识符为 BIPM.RI(II)-K1.Ga-67 . PTB(德国)和 NIST(美国)参与了比较。关键比较参考值 (KCRV) 已使用功率调节加权平均值重新计算。计算了 SIR 和 KCRV 中测量的每个等效活性之间的等效度,结果以表格的形式给出。还给出了图形演示。
