Description

A first comparison of the standards for air kerma of the Instituto Tecnologico e Nuclear (ITN), Portugal and of the Bureau International des Poids et Mesures (BIPM) has been carried out in 60Co radiation under the auspices of the key comparison BIPM.RI(I)-K1. The comparison result, expressed as a ratio of the ITN standard and the BIPM standard, is 1.0015 (0.0018). The degrees of equivalence between the ITN and the other participants in the key comparison have been calculated and the results are presented in the form of a matrix. A graphical presentation is also given. (authors)
