Motion picture, professional films and special processes

Travelers probably shouldn't worry about possible X-ray damage when hand-carrying their film onto the airplane unless they are carrying:



Highly sensitive X-ray or scientific films.

Film with an ISO speed or Exposure Index (EI) of 400 or higher.

Any motion picture films.

Film of any speed that is exposed to X-ray surveillance more than 5 times (the effect of X-ray screening is cumulative).

Film that is or will be underexposed. (See Note 1 below.)

Film that you intend to "push process." (See Note 2 below.

In any of these cases, you should request visual inspection of your film and of any cameras containing film. Depending on the format(s) of film you have, carrying a light-tight changing bag may be advisable to help the inspection process. Remember that this is only a guaranteed option in U.S. air travel. Outside of the U.S. you are required to comply with the local standards and regulations.
