title: A simple source of fluorescent x rays for the study of radiographic imaging systems.
abstract: The properties of a simple source of fluorescent x rays were investigated with regard to its suitability for the study of radiographic imaging systems. The source, consisting of a diagnostic x-ray tube, fluorescent targets, and filters, was found to yield highly monoenergetic x-ray fluxes with intensity sufficient to allow the speed of medium- and high-speed screen-film systems to be studied as a function of x-ray energy.
