FWIW, the UV radiation is indeed more intense at higher altitudes, but the windows of pressurized aircraft filter out 100% of it, so it isn't a factor. Plexiglas windows in smaller planes let it all through unless the window has a special UV tint, but the windows in pressurized aircraft are made with layers of both glass and plastic, as well as the metal used for anti-ice.
Pilots who fly at high altitudes aren't off the hook though. Being above most of the atmosphere exposes you to cosmic radiation, but it's the greatest problem for those who fly long-haul (high altitudes, long duration, high latitudes near the thinning ozone layer). I read somewhere that pilots crossing the North Atlantic under worst-case conditions (after a solar storm) are exposed to the equivalent of 10 chest X-rays. If you do that regularly, it will add up after a while!
