Are there any good clothes to wear to prevent radiation damage from flying?

Yes, but why bother. Lead lined clothing will block the rays. But there is such minute exposure, why bother. How do u plan on getting past the metal detectors. Your question is one of many examples of the unfounded ears that are so rampant in america, reaching hysterical proportions.
Yes if you work as a. Pilot, in flight engineer or flight attendant. Or if you have a fly with no security check up pass. You will have more lead on you than the local fire range on a busy day! you can't fly wearing a lead apron, plus the amounts of radiation are less than 45 seconds in front of the microwave! please stop listening to whomever you listened or read this stuff from. Really, start watching reality tv.
