The use of X-rays in the screening of passengers' luggage and similar packages entering airport secure areas requires consideration of the possible effect on contents therein. Among commonly carried items, the possibility of damage to photographic film is a great concern to the traveling public. This paper presents a study of the possible effects on conventional camera films plus results of some practical tests and a summary of passengers' experiences as reported to a major photofinishing and film manufacturing organization. Also included are results of measurements on the sensitivity of several commonly used films to low-level X-ray exposure. To protect unprocessed film from significant effect, it is recommended that individual X-ray inspection exposures be kept below 1 mR, and that no more than 5 mR be permitted to accumulate from multiple inspections. An explanation of these limits is given, and recommendations to the traveler for protecting the film against excessive X-ray exposure are briefly discussed.
