Is the effect of the airport scanners really that bad?
It's been a while since I've flown anywhere, but I used to fly semi-regularly for work. I often requested hand-checking of film. Sometimes, especially when busy this request was refused.
I also carried the cameras through though, I always figured their metal shell protects the film sufficiently.
In the end, neither the film in the cameras nor the carry-on film ever had any significant defects. At least defects that would be outside of my control (Bad pictures, sloppy loading, sloppy development, etc. etc. ;-)
