Calculation of damages of Auger electron emitting from radionuclides based on 1ZBB model: a simulation study using the Geant4 toolkit

When an ionizing beam enters a living cell, it interacts with the cellular material, thereby transferring some of its energy to it. In this study, the propagation of Auger electrons and their effects as DNA damage by some radionuclides, were analyzed using the Geant4-DNA Toolkit with the 1ZBB model. The 1ZBB model is selected from the protein data bank library which simulates the location of atoms in the sequence of cellular chromosomes. The average number of DSBs is shown as a function of energy. In this study, it is shown that the most damage is caused by Auger electrons with energies of less than 1 keV which corresponds to Auger electrons in layers M, N.
