| Abstract: | Monte Carlo simulation of irradiation of the gold nanoparticles with diameters from 2 to 100 nm in aqueous medium by 20-100 keV photons is performed. Radial distributions of the absorbed dose and dose enhancement ratios are obtained. It is shown that at distances from the nanoparticle center up to 150-200 nm, the absorbed dose increases hundreds of times as compared with the case of the irradiation of pure water. The main transmitters of energy from NPs to the environment are Auger electrons emitted by ionized gold atoms during the cascade decays of inner-shell vacancies |
