(a) Comparison of the radial dose deposition per ionization for a single 10 nm GNP in a SOBP proton beam, a 6 MV photon beam (at depth of PDD80, electron component and photon component, separately), and a 250 kVp photon beam. (b) Comparison of the radial dose deposition per ionization for three GNP sizes in a SOBP proton beam at SOBP2.
