Originally posted by gofour3 Airport hand luggage scanners will not affect film these days, unless it's over 800 ASA. I've put film through airport x-rays machines numerous times and have had zero issues over the last 45 years.
I am glad to hear that youʻve had zero issues with hand luggage scanners, but I cannot say the same. Iʻve lived on Oahu for over 20 years now, and fly out of Honolulu typically three times per year. Iʻve seen x-ray damage to ISO 100 and 400 films that were hand carried, but not hand inspected or in the protection of a lead-lined bag. Yes, TSA has signs and claims that 800 ISO films and lower are not affected by their carry-on scanners, but Iʻve found that is not always true.
In part, it may be a cumulative problem, where Iʻm on my way to Winnipeg and the film is scanned in Honolulu, I spend a day in Vancouver where it is scanned again, and then in Winnipeg on my return flight. Also Iʻve seen security scan it once, stop it, reverse it, scan it again, and even repeat that several times.
Maybe itʻs more of an issue with 120/220 roll film as there is no 35mm metal cassette to offer a bit more protection from radiation. I shoot with 645, and the OP with his 67 would be too.
