Photography; Direct-exposure medical and dental radiographic film/process combinations; Determination of ISO speed and average gradient
Описание (англ.):
The specifications do not apply to film/film-process combinations for mammography. Sensitometric procedures are described for films exposed directly to X-rays. A method is to be provided for the measurements of ISO speed and average gradient so that the characteristics of the film/film process system can be obtained reproducibly and can also be compared with those of other systems.
