Abstract : Experimental data on the characteristics of the solid state intensifying screens manufactured by the U. S. Radium Corporation under NOrd Contract 18369 are presented. Brightness measurements as a function of X-ray intensity fro 90 kvp to 10 Mev are given. A comparison of screen charact ristics is made relative to a standard fluorescent screen at low X-ray energies and to a NaI crystal at high energies. The increased brightness and contrast of the solid state screen is demonstrated. The equation describing screen brightness in terms of the various cre n parameters is derived. Experimental data is given in support of the e equa ions.
