Specific absorbed fractions (SAF) and S-values (S), which are related to internal radiation dosimetry, can currently be estimated using a variety of Monte Carlo tools, including MCNP and GATE, in order to prevent biological damage from being done to tissues and organs after they've been exposed to ionizing radiation. For physicists with coding skills, such tools make physics easier. However,...

14. A nanodosimetric study of cosmic radiation in the organs of astronauts on the lunar surface

A multiscale approach was developed for the first time and used to assess the early DNA radiation damage due to galactic cosmic ray (GCR) protons and the resulting backscattered lunar radiation (BLR) on the surface of the Moon using Geant4. Male and female astronauts were modelled using the ICRP145 tetrahedral mesh phantoms. GCR protons were modelled incident on the Moon surface with an...

16. The TOPAS Tool for Particle Simulation

TOPAS wraps and extends the Geant4 Simulation Toolkit to create a tool that is at once highly flexible and easy to use. Originally created for medical physics under 12 years of funding from the National Cancer Institute, TOPAS is now available to all users completely free of charge under the most permissive style open-source license. While TOPAS has the full Geant4 at its core, it wraps Geant4...
