A New Evaluation of the Decay Data for 166Ho



Brian E. Zimmerman


The beta emitting radionuclide 166Ho has garnered attention over the years as a potential radiolabel for therapeutic medical applications. A new decay data evaluation for 166Ho has been performed using the Decay Data Evaluation Project (DDEP) methodology taking into account recently published experimental data. New recommended values for the half-life, γ-ray emission probabilities, β−- branching ratios, and other relevant nuclear and atomic data are provided. This paper provides a summary of the evaluation; the complete set of recommended data tables and detailed evaluator comments are available at the DDEP website.
