Radiation Energy Deposition



A photon enters the volume with an energy of 11.53 MeV. The primary photon is absorbed via the photoelectric effect by an electron, which had negligible binding energy. The first photo-electron loses 6.80 MeV in collision interactions before changing direction and emitting a bremmstrahlung photon that has 1.56 MeV of kinetic energy. The first photo-electron loses 1.43 MeV in collision interactions before changing direction and emitting a bremmstrahlung photon that has 1.01 MeV of kinetic energy. The first photo-electron loses 0.25 MeV in collision interactions before changing direction and emitting a bremmstrahlung photon that has 0.25 MeV of kinetic energy. The first photo-electron loses 0.07 MeV in collision interactions and then exits the volume. The first bremmstrahlung photon then leaves the volume with its remaining energy. The second bremmstrahlung photon then leaves the volume with its remaining energy. The third bremmstrahlung photon then leaves the volume with its remaining energy. The figure above depicts the particle paths. What are the following radiation energy deposition quantities, in MeV?

Energy Transferred (E_{tr}): MeV
Net Energy Transferred (E_{net}): MeV
Energy Absorbed (E_{abs}): MeV
