    I don't have any statistics about international standards. But since my personal standards are quite nitpicky, I did run some TMY400, both sheet and roll, thru TSA carry-on Xrays three times, then measured for any fog whatsoever with my densitometer. None. This was compared to
    a reference standard, without any XRay. Made me feel more comfortable about domestic flights at least.

    The problem is that the data is so out of date it's meaningless, things have moved on. You need a reality check.

    Earlier today I put up a post with some links to photos that were from film through many scans.
    A message ( first time for me) came back saying the post would be checked by mods, but it seems to have disappeared.

    Thought I'd dig this up again. I'm currently travelling through Asia and had all my bags scanned through a bigger machine when going through customs in Kota Kinabalu. Are these machines bigger versions of the hand luggage machines, or are they more akin to the checked in machines?

    Cheers.

    If the machine was big it is probably what you are calling a "checked in machine". If the equipment said "Invision" on the side, then it is a CT (or two-phase X-ray and CT if they have newer equipment).

    This is why I generally stopped participating in these kinds of threads. Few will either put up data (or even valid looking information) and most seem to have little clue about the technology or security screening marketplace.

    Some data is better than no data... and date alone doesn't determine validity.

    If anything, the situation for air travelers has been trending toward less risk of film exposure to xray/CT than more.

    Its too late now, but do you think I should be concerned?

    Yes, you should be concerned but since it is too late... don't lose any sleep over it. It is impossible to know if CT was applied to your bag, which would most likely affect your film. There have been enough self-reports by folks who put film in checked luggage with no detrimental effect to convice me that the newer two-phase screening equipment is reducing the probability of problems... but only processing the film provides evidence of YOUR film getting CT or no CT exposure. If all your film got was x-ray, there is little to worry about. Since it is too late, though... don't lose any sleep over it.
