What's the story with radiation shielding on ships and orbital habitats in Traveller? Solar storms, Van Allen belts, and the radiation belts of gas giants are never mentioned as a hazard (that I know of), but I seem to remember something about radiation killing crew in space combat.

Is there a canonical explanation in terms of physical or magnetic shielding? Or are cosmic radiation and radiation belts simply ignored without explicit explanation?
