Where do you get the information about notoriously high powered X Ray machines? First I've heard of it.

There is a photography industry in Europe, professional and amateur. These photographers travel a lot by air and rarely get hand checks. And yet you don't see thread after thread in forums along the lines of "The X Rays ate my pictures" or "How can I possibly earn a living when I can't even get my pictures home". And you didn't see threads like that when everyone used film either. Sure you can get processing in European cities, and you can if you wish spend part of your vacation time getting to a lab to drop them off and then back again to collect, and lets hope they do as good a job as your lab back home. Oh, and I don't believe exposed film is any more susceptible to X ray damage than unexposed film.
