A film cassette designed to receive photosensitive film in a light protective envelope and maintain lighttight integrity while removing the protective envelope includes means for bringing a light emitting enhancer screen into intimate contact with the photosensitive film during exposure to x-ray photography. The back of the photosensitive film may be brought into intimate contact with a film or sheet of specimen-containing radioactive or radiation generating material.
