[Gate-users] Reducing photon penetration

[Devir-Wolfman, Ayeleth (GE Healthcare)]

Hi All,

I simulate a simple detector, and I would like to measure how much the photon penetration is affecting it.

I'm trying to reduce the photon penetration through solid materials (of which major parts of the detector are made).

So, what I want to know if it is possible to "cheat" GATE from photons penetration, in the same way it is possible to "remove" radioactive decay processes.

Thank you,
Ayeleth Devir-Wolfman.
