Welcome to the Internet page of the Geant4-DNA project.

The Geant4 general purpose particle-matter Monte Carlo simulation toolkit is being extended with processes for the modeling of biological damage induced by ionising radiation at the DNA scale. Such developments are on-going in the framework of the Geant4-DNA project. This project was originally initiated by the European Space Agency (ESA). Developments are undertaken by an international collaboration, coordinated since 2008 by the National Institute for Nuclear and Particle Physics (IN2P3) of the National Centre for Scientific Research (CNRS) in France.

Once published, all developments are freely accessible in full open access through the Geant4 toolkit or through our freely accessible Geant4 Virtual Machine.
