Abstract
AbstractThis paper describes the development of a radioisotope x-ray fluorescence gauge built to continuously measure and control the coating weight of wet silver emulsion. The method and apparatus for correcting the basic measurement for variations in water content and base film thickness are described. Design considerations, including source selection and arrangement to minimize radiation scattering and emulsion exposure while providing acceptable measurement precision or accuracy, are discussed.
