Dear fluka user,
Recently, I'm researching the induced radioactivity in the electron linear accelerators which energy is about 10~20MeV.
I want to use FLUKA to do some caculation about induced radioactivity. I have found some results caculated by FLUKA from some paper got from Internet. But I found these results are in very high energy(several hundred MeV or GeV). And It seems I can't get the accurate result in my example. My result using the RESNUCLE is always zero. Would you mind provide some examples or some papers in this aspect? By the way, can you help me check my input file? Thanks a lot!
