title: An evaluation of screen-film speed characteristics.
abstract: The relative speeds of six commercially available screen-film combinations were evaluated. There is a nonlinear relationship throughout the kVp range between the calcium tungstate, barium strontium sulfate, and rare earth screens. The speed of the last two types falls off considerably at lower kVp levels.
