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.

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。
