Dear Roxana,
for both questions: if you have defined your irradiation profile and
switched on the residual radiation treatment via the other
radioactivity-related commands (RADDECAY and DCYTIMES), you always obtain the
results normalized per unit time (per s) *if* you associate a decay time to
your estimator -USRBIN, RESNUCLEi in your case- via DCYSCORE.
Therefore:
1. when you score ACTIVITY you obtain results in Bq/cm^3, for the considered
decay time;
2. when you plot the RESNUCLEi output in the A-Z plane you get results in
Bq/cm^3 (always for the given decay time), *if* you gave in input the region
volume (otherwise you obtain the activity integrated over the analyzed
volume).
If instead the RESNUCLEi detector is not associated to any decay time, then
you get results in nuclei/cm^3 per primary (provided that the volume is
given, as said above, otherwise the volume is set to 1)
Best regards,
Anna
