It is extremely important to understand and model the Martian radiation environment in preparation for future human missions to Mars, especially during extreme and elevated conditions such as an intense solar energetic particle (SEP) event. Such events may enhance the radiation level drastically and should be forecasted as soon as possible to prevent severe damage to humans and equipment. Besides, the omnipresent galactic cosmic rays (GCRs) also contribute significantly to the radiation in space and on the surface of Mars and may cause long-term damages to current and future missions. Based on
GEANT4 Monte Carlo simulations with the Martian atmospheric and regolith environment setup, we have
calculated and obtained some ready-to-go functions which can be used to quickly convert any given SEP or
GCR proton/helium ion spectra to the radiation dose on the surface of Mars and also at different depth of
the atmosphere. We implement these functions to the RADMAREE tool under the Europlanet project
which can be easily accessed by the public.
