<g>  Do I see another film testing catagory for Don Westergren?  Which films
are radiation resistant?

Really though, the radiation exposure constraints on the film used on 6
month missions on the ISS seems to be non-trivial.  But my underlying
concern in light of that is what about the people up there?  If the overall
dose is enogh to cook 800 speed film, what is it doing to the folks using
the film?
