Determination of the absolute photon emission intensities of some gamma rays of 166mHo

This paper presents the results of the absolute measurement of some photon emission intensities in the decay of 166mHo. Point sources from a reference solution standardized in the frame of the EURAMET.RI (II)-K2. Ho-166m activity comparison were measured by gamma spectrometry. The detection efficiency was obtained by Monte Carlo calculations including the complete decay scheme. Results obtained for 27 gamma and X-ray emissions are compared to reference values.
