Micro-dosimetry and numerical simulations

The modelling activities of the iRiBio group are focused mainly on the extension of the general purpose and open source Geant4 Monte Carlo simulation toolkit (Geant4 andGeant4@IN2P3) at the frontier between low energy physics, biology and medicine, in particular in the context of the Geant4-DNA project, coordinated by the iRiBio group. These developments, in full open access, include new models for the description of physical and physico-chemical interactions of elementary particles with biological medium, and the modelling of water radiolysis. They also include geometries of biological targets and example user applications for the community. In parallel, Geant4 simulations are also developed for the modelling of specific radiation environments for archaeometry (dating of buried samples) and exobiology (search of traces of life in the Solar System). Finally, we regulalry contribute to the orgaziation of Geant4 and Geant4-DNA conferences and tutorials.
