I've installed Geant4 10.2-beta. But I'm still receiving 2.5 MeV gammas from Co60 source.

If I'm switching on Geant4-10.0.4 I'm receiving following message (and correct gammas with energies 1.17 and 1.33 MeV ):

-------- WWWW ------- G4Exception-START -------- WWWW -------
*** G4Exception : HAD_RDM_011
      issued by : G4RadioactiveDecay::GetMeanFreePath()
Ion has negative lifetime -1001 but is not stable.  Setting mean free path to DBL_MAX

*** This is just a warning message. *** -------- WWWW -------- G4Exception-END --------- WWWW -------

Please, what is the best decision to make decay of Co60?

Vladimir
