(B) Energy deposited in matter (E_matter) for one γ photon interaction in a tumor of volume V_tum loaded with 10 nm diameter nanoparticles, with an occupation ratio of 7 × 10^-3. The absorption of the photons (Abs.) is calculated for the two considered energies (100 keV and 500 keV). η_nano quantifies the fraction of energy that is deposited in the nanoparticles themselves.
