Dear Fan, Thank you very much for your valuable information.

As an example, I looked into the file "z27.a60" in $G4RADIOACTIVEDATA for 60Co decay. It seems that it only contains data for radioactive decays but the EM decays in the daughter nuclide and that to follow the whole decay we need the "z28.a60" in $G4LEVELGAMMADATA. Then, for 15N(10.8MeV) case, I think we need two "z7.a15" files, one in $G4RADIOACTIVEDATA to provide starting point of the decay, and the other in $G4LEVELGAMMADATA to proceed EM decays (though formats of the two files would be different). Am I correct? Could you give me pointers to formats, sources, and policy of the data files in the two directories? Thank you in advance.
