Description
The study of the effects of space radiation on astronauts in an important concern of
space missions for the exploration of the Solar System. The radiation hazard to crew
is critical to the feasibility of interplanetary manned missions.
To protect the crew, shielding must be designed, the environment must be
anticipated and monitored, and a warning system must be put in place.
A Geant4 simulation has been developed for a preliminary quantitative study of
vehicle concepts and Moon surface habitat designs, and the radiation exposure of
crews therein. This project is defined in the context of the European AURORA
programme, whose primary object is to study solutions for the robotic and human
exploration of the Solar System, with Mars, the Moon and the asteroids as the most
likely objects.
This study intends to evaluate wheter the energy range typical of the radiation
environment of interplanetary missions is adequately treated in Geant4 physics
packages, for all the major types of particles involved, identifying the availability
of appropriate electromagnetic and hadronic physics models and verifyng the status of
their validation. Recommendations for further Geant4 developments or improvements
and of further validation tests, necessary for the interplanetary manned missions,
are issued as a result of this study.
