The need to assess the effects of radiation on spacecraft is becoming increasingly
important due to the increased sensitivity of microelectronics and sensors and the reduced
availability of radiation hard alternatives. Monte Carlo simulation offers the ability to model in
detail the physics of space radiation to assess and optimise hardening strategies. Geant4 is a
new-generation toolkit for Monte Carlo simulation, intended for a wide range of applications,
including space. The current version of this code provides in a single tool comprehensive
treatment of the physical processes from PeV energies of hadronic interactions, to <1 keV for
electromagnetic interactions and ~eV energies for neutron transport.
The European Space Agency as part of the Geant4 international collaboration is
supporting the development of Geant4 with the objective of making the code the basis of a general
space radiation shielding and effects tool (SPARSET). This paper will review the physical
processes modelled by Geant4 in the context of the user requirements for space radiation effects
analysis. An overview will also be presented of the current and planned developments in Geant4
funded by ESA.
