title: Regional silver content of radiographic film determined by x-ray fluorescence compared with optical densitometry.
abstract: The regional silver content of radiographic film measured by x-ray fluorescence is compared to light absorption measured by a densitometer. Silver content analysis appears to permit a greater dynamic range of useful exposure levels than does light absorption densitometry. This improvement in latitude, however, is not considered great enough to warrant development of a complex system for scanning silver distribution in radiographic applications.
