title: Medichrome film as an alternative to silver-free recording systems.
abstract: A shortage of silver is forcing film manufacturers to lower the silver content of radiographic films.  No further lowering seems possible without film quality being adversely affected. Various ways to solve the silver problem in the future are discussed and colour radiography is regarded as one solution since it makes possible a high degree of immediate recovery of silver.  The feasibility and proper use of the only colour film available, Medichrome, is discussed.  Suitable screens in order to compensate for the low sensitivity of the film without loss of image quality and a strong light source containing a monochromatic sodium lamp for inspection of dense areas are recommended.
