A radial symmetry distribution of the energy deposition from secondary electrons emitted from the nanoparticle was assumed \cite{McMahon_2011a} \cite{McMahon_2011}  and reconstructed through the simulations. The phase-space of the secondary electrons was sampled on the GNP surface and the following energy deposits in the water volume surrounding the nanoparticles were histogrammed radially, putting the GNP at the origin, with a bin width of 1 nm up up to a distance of 5000 nm. The simulated dose distribution profiles following a single ionizing event by a 2 nm GNP in water during irradiation with different monoenegergetic photons with energies between 20 keV and 15 MeV are shown in figure [radial dose, panel A]. The actual shape of the radial dose profile to be found in a realistic treatment irradiation was obtained through a weighted superposition of the monoenergetic profiles, using specific photon spectra.
