摘要：
A comparison of the standards for air kerma of the Hungarian Trade Licensing Office (MKEH), Hungary and of the Bureau International des Poids et Mesures (BIPM) was carried out in the Co-60 radiation beam of the BIPM in March 2016. The comparison result, evaluated as a ratio of the MKEH and the BIPM standards for air kerma, is 1.0047 with a combined standard uncertainty of 1.9 x 10(-3). The results for an indirect comparison made at the same time are consistent with the direct results at the level of 2.6 parts in 10(3). The results are analysed and presented in terms of degrees of equivalence, suitable for entry in the BIPM key comparison database.
