Hello,

There are two stages of simulation which you need: production of isotopes and an isotope decay.

As Michel pointed out Geant4 has radioactive decay database, you can exercise it with the extended example "exrdm". For me it is meaningless to learn and to add external package, when corresponding module already exist.

However, there is another difficulty: isotope production never was a priority of Geant4. Recently isotope production was improved in Binary cascade, it is reasonable in the Bertini cascade but, unfortunately, there are no systematic studies with published results showing that the probability of one or another concrete isotope is compared with the data. Some results were recently reported for medical carbon beam in water, some results exist for mean Z and A production in high-Z targets. In any case one need to use Binary or Bertini cascades.
