Likewise any atmosphere reaching Earth-like levels of breathability will stop such particles as well. The surface of some of the real world Galileans is dangerous to humans in thin-skinned suits or vehicles is because there is no significant atmosphere.

To that, you could also add that humans evolved in a high radiation environment may have adapted a resistance to that radiation (see the theory of radiation hormesis).
