Abstract: Two series of activity standards of 60Co in cast steel matrix, developed for the calibration of gamma-ray spectrometry systems in the metallurgical sector, were characterised using a European interlaboratory comparison between twelve National Metrology Institutes and one international organisation. The first standard, consisting of 14 disc shaped samples, was casted from real contaminated steel, and the second, consisting of 15 similar discs, from artificially contaminated steel. The reference activity concentrations of 60Co in the cast steel standards were (1.077 ± 0.019) Bq∙g-1 and (1.483 ± 0.022) Bq∙g-1, respectively.
