Hello Martin,
The most common way is folding of fluence with fluence-to-dose equivalent
conversion factors. If folding is performed off-line you will need energy
spectra which can be scored with either USRTRACK or USRBDX. On the other
hand (and this is usually more convenient), you could request a USRBIN
scoring and fold online using the user-routine fluscw.f. This routine
allows one to multiply every entry into the scoring-bin with particle type
and energy-dependent factors, e.g. fluence-to-dose equivalent conversion
factors.
At CERN we are using the fluence-to-dose equivalent conversion factors as
calculated with FLUKA by Mauricio Pelliccioni in a fluscw-implementation
written by Graham Stevenson and myself. You are welcome to use it- pls let
me know!
Regard
stefan
