Hi Francesco,
According to the FLUKA manual: "There is the possibility of selectively
changing regions to vacuum/blackhole (and/or switching on/off possible
fields) when transporting radioactive decay products."
See WHAT(6) of the ASSIGNMAT card:
http://www.fluka.org/fluka.php?id=man_onl&sub=10
If you want to get the activation in the sample only, then you have to set
the WHAT(6) of ASSIGNMAT card for the sample to be VACUUM.
Cheers,
-Nikhil
