Hi Metin,
first you can have both USRBIN in the same input file and score the two
quantities independently.
I don't get exactly what you are trying to do. Anyway there's a mistake in
the PET input: you try to score the activity using WHAT(1)=11 which is not
allowed and will give you inconsistent results for 10<=WHAT(1)<=18 you can
score only quantities along a step, and ACTIVITY is one of the forbidden
ones (see the manual for more details). You probably should score it "at
point".
For an example of scoring the ACTIVITY take a look at those lectures from
the FLUKA course
https://indico.cern.ch/event/296741/timetable/#20140516
*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....
USRBIN 11. ACTIVITY -21. 5.0
10.0activity
USRBIN 0.0 0.0 200. 200. 200.

Best,
