Fig. 9:

Expected mean imparted energies in 10 nm-thick radial shells around a 50 nm GNP irradiated by the 50 kVp spectrum at a particle fluence producing an absorbed dose of 2 Gy in the absence of the GNP. The small full symbols indicate the average imparted energy around the GNP, and the solid line indicates the mean imparted energy in the absence of the GNP. The data for a GNP experiencing one or two photon interactions are shown as filled and open symbols respectively.
