A powerful and suitable tool for attacking the problem of the production and transport of different beams in biological matter is offered by the Geant4 Simulation Toolkit. Various activities in progress in the domain of medical applications are presented: studies on calibration of brachytherapy sources and thermoluminescent dosimeters, studies of a complete 3-D inline dosimeter, development of general tools for CT interface for treat ment planning, studies involving neutron transport, etc. A novel approach, based on the Geant4 Toolkit, for the study of radiation damage at the cellular and DNA level, is also presented.
