The GATE Monte Carlo simulation platform based on the Geant4 toolkit is in constant improvement for dosimetric calculations. In this paper, we present the integration of Geant4-DNA processes into the GATE 7.0 platform in the objective to perform multi-scale simulations (from macroscopic to nanometer scale). We simulated three types of clinical and preclinical beams: a 6 MeV electron clinical beam, a X-ray irradiator beam and a clinical proton beam for which we validated depth dose distributions against measurements in water. Frequencies of energy depositions and DNA damage were evaluated using a specific algorithm in charge of allocating energy depositions to atoms constituting DNA molecules represented by their PDB (Protein Data Bank) description.
