Is it safe to put your film through the airport X-ray machines?

The National Association of Photographic Manufacturers recently tested nearly 500 rolls of Agfa, Kodak, Fuji, Ilford, Konica and 3M film. Here are their surprising results: Repeated exposure, even up to 100 times, is virtually harmless in airports that are regulated by the U.S. Federal Aviation Agency. This includes all films, including high speed films of ISO 1600.

However, this applies only to film that you carry with you on board. Film that you pack in your checked baggage is examined by a high-intensity scan which can damage it. And worse for photographers, the FAA has just certified a new baggage scanner called the L3 Communications Examiner 3DX-600 which causes even more damage than the scanners currently in use. So, bottom line, don't pack your film in your checked baggage.
