Description

A first key comparison of the standards for absorbed dose to water of the Korea Research Institute of Standards and Science (KRISS), Republic of Korea, and the Bureau International des Poids et Mesures (BIPM) was carried out in the 60Co radiation beam of the BIPM in March 2022. The comparison result, based on the calibration coefficients for two transfer standards and evaluated as a ratio of the KRISS and the BIPM standards for absorbed dose to water, is 0.9986 with a combined standard uncertainty of 3.8 parts in 103. The results are analysed and presented in terms of degrees of equivalence, suitable for entry in the BIPM key comparison database.
