LIP has been cooperating with ESA, the European Space Agency, in the application of the GEANT4 simulation toolkit to astroparticle experiments and in the description and study of the solar system radiation environment and its effects on electronic components relevant for ESA future space missions.

The high energy ionizing radiation environment in the solar system consists of three main sources: the radiation belts, galactic cosmic rays and solar energetic particles.

Geant4, a Monte Carlo radiation transport simulation toolkit, with applications in areas as high energy physics, nuclear physics, astrophysics or medical physics research, is being used to model and study the effects of the heliospheric radiation environment. Specific applications are being developed to study the effect of the radiation environment on detector components, to describe the response and to optimise the design of radiation monitors for future space missions and to predict the radiation environment in Mars surface, orbits and moons.
