Magnetosphere of planet like Jupiter or Saturn is the most radioactive place in solar system... Also energies (delta V) needed to travel between Jupiter moons are greater, than those needed for travel between solar planets.

I thought Saturn was mostly benign. My hope was that a magnetosphere would protect the moons from the early outbursts of the red dwarf.

That's surprising. Found this nice map [1] and the numbers are really disappointing. ~15 kps from Titan-to-Iapetus sucks (even though it's ~4 kps less than Earth-to-Mars). At least the distances are smaller...
