the result from Detect card is:
obviously, it is wrong, so The result from Detect card is wrong when using isotope as a source?

Dear Siyuan1987,
The isotope source in FLUKA will give you not only the gamma lines but the electron from beta decays and alphas as well.
If you look at the decay scheme of the Co-60, you will see that first it beta- decays to Ni-60*, and only then you get the two gamma lines.
The maximum energy of this beta decay is 318 keV, which explains the smearing of the first results.
Furthermore, you need to increase the maximum energy of the scoring to ~3 MeV, since in most of the cases, both of the photons and the electron of the beta- decay are stopped from the same decay.
Cheers,
David
@horvathd , yes, you are right, in radioactive isotope source, an event begin from emitting a electron and end to emit all the photons, when increase the maximum energy of the scoring to ~3 MeV, the result is:
