This may all be true but consider; JandC photo has a "NO X-RAY" tape they put on the boxes; anyone remember seeing them? I have had a career in Radiology and Radiation Therapy. In an x-ray film cass. there are "screens" of rare earth that when "hit" with x-rays emits light to expose the film. I would like to see someone really test the films by taking some of differing speeds and going through some airport scanners. I.E. slow, medium, fast, some of each. Develop after a set after one round trip, two trips, three trips etc. At some point there should be an elevated FB+Fog. I found that it isn't worth the time to ask for a hand inspection. They just look at it, hold you up, then put it through the scanner anyway.
