Function

Used to hold and protect prepared x-ray film before, and in some applications during, exposure within a cassette.

Technical

Exposure holders were available with and without lead backing. When used with a film cassette the lead foil, in direct contact with a sheet of x-ray film, increases the photographic action on the film; absorbs longer wavelength scattered radiation; & intensifies primary radiation. (ref.1) black paper inside the folder protects the film and was left on unless/until film was loaded in cassette w. screens.
