Films are fine and safe at Turkish and other airports, mine gets scanned regularly and many multiple times. I've just retuned with some this morning scanned at Birmingham, but some I used while in the UK had been scanned before more than a dozen flighs, and daily re-boarding a cruise ship for a week in my back-pack

There's no issues with over 99% of airport scanners and hasn't been for many years, except a few smaller US airports still using older machines.
