X-Ray Lead Intensifying Screens
Lead Intensifying Screens are thin sheets of lead foil mounted on card for ease of handling.
One is placed on each side of an x-ray film and in close contact with it, inside a cassette or
film-holder before exposure. They are used in most radiographic techniques, excluding some
of those employing low kilovoltages, because they reduce the exposure required and improve
the quality of the image. The screens are made from the finest available radiographic lead foil,
laminated onto flexible white photographic base card.
