This study uses a model we developed at IRAP to evaluate the effect of Ganymede and its magnetic field on the energetic electron flux received at different orbits for a potential Ganymede orbiter. We have found that 3 physical processes tend to reduce electron flux during a Ganymede orbit. 1) Magnetic shielding above equatorial region 2) loss cone above polar cap and 3) emptying of flux tube due to electrons bouncing inside Jovian radiation belt flux tubes. The overall mean effect of these processes will result on a diminution of total radiation dose of at least 50% for low altitude circular polar orbit with variation with energy, orbital parameters and magnetic field configuration.
