regarding your question and the answer you got I MUST add something:

What Laurent says about the limits is correct, Zmax = 100 and Amax=250. But no matter how you try to change those numbers you cannot do it. Either the macro command or via the SetNucleusLimits() mentioned will fail to achieve what you need since the argument of both of those methods is a G4NucleusLimits object and the constructor for those objects clearly establishes some specific limits:
Z -> [0,100] Amin -> [1,240] Amax -> [1-250]
So as far as I can see your only option is to modify the Geant4 source code and recompile your installation so it includes higher limits that you can later modify with the mentioned methods by Laurent. btw, just for simplicity I would go for the macro command level that has worked very well for me so far.

Check the file $G4RADIOACTIVEDATA/README_RDM ! It will give you the description of the files :D
