Sorry I've missed that. If you use semi-analogue, is true it scores both the prompt and decay
over a time window which is infinite (unless if you have a cut in time) and the results are
normalized per decay. Having an ISOTOPE decaying as a beam according
to the BEAM is not permitted to have an IRRPROFILE (Note.8 of BEAM card).
FLUKA will not complain though and my guess is that it will simply sample the starting
time from the irradiation profile.

Dear Vasilis,

The thing is with DCYSCORE set to Semi-analogue mode, the detector turn to score both prompt and decay particles combined.
And my problem is how to present the units of this combination.

Dear Nkanyiso,

all quantities in the decay part of the calculation are expressed per unit time pSv/s.
In the prompt part of the calculation are expressed as pSv/primary

Dear FLUKA users,

I have a confusion with the units of the USRBIN DOSE-EQ scoring detector.

I have set the USRBIN DOSE-EQ scoring detector associated with DCYSCORE in Semi-analogue mode since I want to score prompt-decay particles, and I have also defined the irradiation profile using IRRPROFIle card.

So I'm confused if my units for DOSE-EQ should be in pSv per unit primary weight, since my DCYSCORE is in Semi-analogue mode, or they are expressed in pSv/s, since I have define the irradiation profile.

And if the units are expressed in pSv per unit primary weight, can I just multiply with my beam current (in prim/s) to get pSv/s, or I should multiply with the total particle statistical weight, which is the number of events requested, to get pSv.

Any suggestion will be appreciated.
Thanks in advance

Nkanyiso R. Mantengu.
