Gold nanoparticles have been reported as possible radio-sensitizer agents in tumor radiation therapy, in particular through the increase of local energy deposition in close vicinity of the nanoparticles and subsequent direct damage to cells and DNA. Moreover, indirect damage originating from the increased production of chemical species induced by such additional energy deposition events around...

The Geant4-DNA extension enables quantitative estimation of biological effects by radiation. Its physics processes generate large amount of low energy secondary particles (~ a few eV). The simulation needs enormous computing time for tracking down to very low energy. This work presents the implementation of the physics modes of Geant4-DNA in GPU architecture. We have observed significant...
