[gate-users] Cancel Positron Annihilation?

[Nicolas Salem]

Hello all! I am makeing simulation with radioactive sources that have a low
branching ratio for the decay by positron emission. These isotopes emit both
positrons and high energy gammas as they decay. I would like to study these
high energy gammas. To do that, I would like to perform simulations using these
isotopes, simulating their whole decay, but kill the positrons as they are
created. Does anyone know how to do that. Thank you very much!
