None Can I turn off some physics processes in a volume?

Dear Geant4 experts,
   1)  The case is a gamma pulsed beam impacting a Ti target. A BGO crystal detector is placed 
behind the target. The dose produced by induced radiation from the target is what I want. 
But It is found the induced dose recorded in BGO is much higher than expected. I guess much
part of the dose may come from the activation of detecor itself . So I want to turn off the 
photonuclear process in the BGO volume to avoid the dose from detector itself. Can I do it?
    If there is another way to solve my problem, I would like to hear. 
  2) another question. If I kill the radionulides produced in detector volume in
UserSteppingAction as soon as these particles produced, will the induced ray still come out
from these unstable nuclides and contribute to the total dose?
     Thanks in advance!
