<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">I simulate a simple detector, and I would like to measure how much the photon penetration is affecting it.<o:p></o:p></p>

<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">I'm trying to reduce the photon penetration through solid materials (of which major parts of the detector are made).<o:p></o:p></p>

<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">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.<o:p></o:p></p>
