A radiographic paper system has been evaluated with and without ultraviolet fluorescent screens over an X-ray energy range from 25 KVCP to 160 KVCP in order to determine its potential for supplementing X-ray film at a cost savings. Part I of this report gave the technique curves for 2024 aluminum from 25 KVCP to 150 KVCP without screens and with Kodak Industrex Intensifying Screen F-1. Detail sensitivity obtained with penetrameters was reported at 2 for this screen over part of this energy range for selected thicknesses of aluminum. Comparison of film and paper radiography was made using two different types of fluorescent screens with aluminum and titanium honeycomb samples. Part II gives the technique curves for 2024 aluminum from 25 KVCP to 160 KVCP with Kodak Industrex Intensifying Screen F-2. Detail sensitivity using penetrameters is reported for selected aluminum thicknesses over this energy range, together with the sensitometric properties such as the characteristic curve, gradient, exposure latitude, and speed of exposure.
