Abstract
The Non-Destructive Assay (NDA) group at New Brunswick Laboratory (NBL) completed the development of a spreadsheet DECAYALL, detailing the complete radioactive decay (parent, all daughters, and stable progeny) of any Th/U/Pu/Am input sample. The completed solution includes dual branch decays, calculating material generated and subsequently decayed through both the a and 0- channel, when applicable. Input includes the mass amount of material present and the isotopic abundances of the material present at time to, and the length of decay time At. The output includes the mass, atom number, and activity of all subsequent decays, from parent through stable daughter.
