On Sunday I passed through airport security with 3 exposed rolls of film. One 200ASA Scala slide, One 400 ASA Ilford XP-2 and one Agfa 160 120 roll film. the airports that scanned the film which was in my carry on camera bag were Boston and Washington (DCA) ALL film was left with NO images on the film. I haven't checked the other film in the bag that was not exposed but these were all lost. I have no other explanation as these were taken with three different cameras and not exposed to heat ro extreme cold and were removed from the cameras within 30 hours of passing through the airports. thought this was not something to worry about but guess I was wrong.
