A new key comparison of the standards for air kerma of the Głwny Urząd Miar (GUM), Poland and the Bureau International des Poids et Mesures (BIPM) was carried out in the 60Co radiation beam of the BIPM during June-July 2020. The comparison result, evaluated as a ratio of the GUM and the BIPM standards for air kerma, is 1.0039 with a combined standard uncertainty of 3 parts in 103. The result agrees within the uncertainties with the direct comparison carried out in 2006. The results are analysed and presented in terms of degrees of equivalence, suitable for entry in the BIPM key comparison database.

波兰 GUM 的空气比释动能标准与 BIPM 在 60Co 伽马辐射中的关键比较 BIPM.RI(I)-K1

2020 年 6 月至 7 月期间,在 BIPM的60 Co 辐射束中对波兰 Głwny Urząd Miar (GUM) 和国际测量与测量局 (BIPM) 的空气比释动能标准进行了新的关键比较。比较结果(以 GUM 和 BIPM 空气比释动能标准的比率进行评估)为 1.0039,组合标准不确定度为 10 3分之3。结果在不确定性范围内与 2006 年进行的直接比较一致。结果以等价度的形式进行分析和呈现,适合输入 BIPM 关键比较数据库。
