Abstract
An indirect comparison has been made of the standards for air kerma and absorbed dose to water in 60Co radiation of the National Research Council (NRC), Canada and of the Laboratorio de Metrologia de Radiaciones Ionizantes (LMRI), Chile. The measurements at the LMRI were carried out in October 2016. The comparison results, based on the calibration coefficients for one transfer standard and evaluated as a ratio of the LMRI and the NRC standards, were 0.9972 for absorbed dose to water, with a combined standard uncertainty of 8.9 × 10-3, and 0.9945 for air kerma, with a combined standard uncertainty of 8.6 × 10-3. The results are analysed in the context of the degrees of equivalence for these quantities published in the BIPM key comparison database. Additional characterization of the LRMI Co-60 irradiator is also described.
