I am wondering what is the best way to get around the xray machines for my b&w film? Can I ask for a hand inspection as opposed the them putting it through the machine? Also, I have just stuffed my pockets with medium format film before (since the reel is plastic, the medal detectors don't go off) but was wondering if the medal detector did anything to my film. Also, i was wondering whether u.s. mail gets xrayed. If not it might just be best to ship my mail home as opposed to worry about the airport. Thoughts?
