Abstract
X-ray intensifying screens of different speed classes are disclosed, showing a synergistic effect between screen speed or sensitivity and image quality, especially sharpness, if for each speed class the right combination is applied for the amount of dye in the screens and the weight amount and weight coverage of selected mixtures of yttrium tantalate or niobate phosphor and rare earth activated alkaline earth metal fluorohalide phosphors coated onto selected supports showing well-determined reflectance characteristics.
