	In the Brem & Ionization simulation the majority of the photon creation happens at the end face of the Tantalum. There is a spike at the first face of the target and also a bit of grass in between, this leads me to believe that the particle tracking in the simulation isn't working correctly, or is counting every interaction of every photon, which would explain why there is a huge spike of counts at the end face of the target.
