Radiation Energy Deposition

A photon enters the volume with an energy of 8.08 MeV. The primary photon is absorbed via the photoelectric effect by an electron, which had negligible binding energy. The first photo-electron loses 2.50 MeV in collision interactions and then exits the volume. 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
