Modeling the radio-induced effects in biological medium still requires accurate physics models to describe the interactions induced by all the charged particles present in the irradiated medium in detail. These interactions include inelastic as well as elastic processes. To check the accuracy of the very low energy models recently implemented into the GEANT4 toolkit for modeling the electron sl...

Geant4 is a Monte Carlo simulation Toolkit, describing the interactions of particles with matter. Geant4 is widely used in radiation physics research, from High Energy Physics, to medical physics and space science, thanks to its sophisticated physics component, coupled with advanced functionality in geometry description. Geant4 is widely used at the Centre for Medical Radiation Physics (CMRP), ...

As simulation system, the variety of physics processes implemented is one of the most important functionalities. In that sense, Geant4 is one of the most powerful simulation toolkit s. Its flexibility and expansibility brought by object-oriented approach make it possible for us to easily assimilate external simulation packages into the Geant4 system as modules of physics processes. We developed...

Monte Carlo computer programs such as the GEANT4 toolkit include precise models of particle interactions and can be an invaluable tool for studying the feasibility of new imaging techniques such as proton computed tomography (pCT). Presented in this paper is a comparison of laboratory data with GEANT4 predictions for the imaging characteristics of a simple metal object using a particle beam and...

The employment of Monte Carlo simulations in the applied nuclear physics techniques has increased with the data processing capabilities of the commercial personal computers. Since the inclusion of the low-energy electromagnetic interactions in GEANT4, this Monte Carlo simulation toolkit has produced results which reveal its promising utilization in radiation dosimetry, radiation protection and ...

Geant4 is a toolkit for the simulation of the passage of particles through matter, developed with advanced software engineering techniques. Its application areas include high energy and nuclear physics experiments, space physics, medical physics and radiation background studies.

A set of physics processes has been developed in the Geant4 Simulation Toolkit to describe the electromagnetic interactions of photons and electrons with matter down to 250 eV. Preliminary comparisons of the models with experimental data show a satisfactory agreement.

The Visualization System of GEANT4 is an interface between the simulation kernel and the graphics system. In itself it defines only the functionality required by the kernel and the GEANT4 user. It contains an abstract interface to which an installer may fit his or her favourite graphics system; concrete interfaces to some graphics systems come ready-to-use with the GEANT4 toolkit.
