Scope

This part of GB/T 24791 describes the shape of the photosensitive characteristic curve, the average slope, and the measurement method of the sensitivity of breast X-ray screens/films/film holders/processing systems. The film holder can be of any form, as long as it ensures that the screen/film is in close contact and prevents the film from being exposed to ambient light. The film holder can be a light-tight vacuum bag often used in experiments, or an X-ray imaging cassette used during breast X-ray photography.
