I took 100 rolls of Neopan 100 (120), and 200 sheets of TXP320 (5x4") - Melbourne-Sydney-Tokyo-Frankfurt-Berlin, then Zürich-Hong Kong-Sydney-Melbourne last year, and couldn't find a trace of fogging in anything. I brought back another ten rolls of TMAX400 from Tokyo (the weather was a bit dark at times for Neopan), and that was fine too. At most, that's 7 journeys through carry-on x-ray without anything that would impact on printing when I got back home. I think it's fair to say I will never bother with the HASSLE of hand-inspection...

Marc!
