摘要：
Ho-166 (T-1/2 approximate to 26.8 h) is an emerging theragnostic radionuclide of interest in nuclear medicine due to its peculiar decay scheme, featuring high-energy beta(-) emission (approximate to 1.8 MeV) coupled with the main gamma-ray emission (approximate to 80.6 keV). Using the new 166 Ho activity standard and the well-calibrated, high-energy resolution HPGe detector, both available at ENEA-INMRI, a new determination of several Ho-166 gamma-ray emission intensities, I-gamma, was performed with low uncertainty. The new I-gamma values contributed to the Decay Data Evaluation Project.
