<p>Hi!</p>
<p><br>
</p>
<p>I don't really consider myself a geant4 expert, but from what I have read in the geant4 physics list documentation I would think that the "Shielding" physics list was more or less designed for topics like what Mohamad is trying to investigate.</p>

<p class="MsoNormal">Hi Dr. Grevillot<o:p></o:p></p>
<div>
<p class="MsoNormal">I have question about simulation with GATE framework. I am working on shield of treatment room in proton therapy, And in detail, on neutron dose rate in the back of the each wall. Is it possible to calculate and simulatethe dose rate with
GATE or not? <o:p></o:p></p>
