I usually have my film handchecked, especially since I usually carry at least one roll of 3200 for extreme circumstances which is very sensitive to x-rays. When I flew from Seattle to Dc (Dulles): no problem with a hand check. When I flew back from Baltimore (BWI) to Seattle: a supervisor had to do it, security was not pleased, and I got lots of dirty looks (!) during my hand check.(posted 8275 days ago)Foreign X-ray machines are notorious for using high dosages of x-rays.
I think that I'll carry bulk film, empty plastic canisters, and special film (like 3200 and 1600) in plastic bags for easy hand searches.
