ISOTOPE beam decay data

Dear FLUKA team,
In this context, can you tell to us what the source and the extent of the decay data is that the ISOTOPE particle type provides ?
Thank you,

Dear @totto
fluka contains an internal decay database, with all the branching probabilities from “stable” isomers (t_{1/2} > 10 ns), based on ENSDF and RIPL. Only the positrons, electrons and gammas will be generated and transported.
