Hi all, I think this question goes best in this section, because I think the answer is something a nuclear or particle scientist could answer. In space, what would happen to a ship that did not have proper shielding from cosmic rays? (NOT the astronauts themselves; there is plenty of material on cosmic rays impacting them). I know the electronics would go out, and there would be secondary effects (cascades of particles). What would happen to the hull of the ship? What would happen to an engine if cosmic rays flooded into it? Would the ship melt away? Would there be flashes of ship like on a microwave? I know it depends on the materials, but I couldn't find even a single website on this subject. If you know how any material would transform macroscopically at all when constantly exposed to high energy particles, that would be great. A website or book with more info would help, too.
