A direct comparison of the standards for air kerma of the Istituto Nazionale di Metrologia delle Radiazioni Ionizzanti (ENEA-INMRI), Italy and of the Bureau International des Poids et Mesures (BIPM) was carried out in the 60Co radiation beam of the BIPM in June 2015. The comparison result, evaluated as a ratio of the ENEA and the BIPM standards for air kerma, is 0.9999 with a combined standard uncertainty of 2.2 × 10−3. The results are analysed and presented in terms of degrees of equivalence for entry in the BIPM key comparison database

Abstract
A direct comparison of the standards for air kerma of the Istituto Nazionale di Metrologia delle Radiazioni Ionizzanti (ENEA-INMRI), Italy and of the Bureau International des Poids et Mesures (BIPM) was carried out in the 60Co radiation beam of the BIPM in June 2015. The comparison result, evaluated as a ratio of the ENEA and the BIPM standards for air kerma, is 0.9999 with a combined standard uncertainty of 2.2 × 10−3. The results are analysed and presented in terms of degrees of equivalence for entry in the BIPM key comparison databaseI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
