Dear Agnieszka,
none of the options you indicate make sense. You should just score ENERGY
with USRBIN per region. In the case of a radioactive source you need
DCYSCORE in addition.
Work function is here intended as the conversion between energy deposited
in the gas and charge production/collection, which is not something that
you can simulate explicitly by FLUKA.
Kind regards
Francesco
