A matrix method of determining transmission, scattering, and absorption of radiation, such as gamma rays and neutrons, in large thicknesses of matter is presented. Experimental data as yet unavailable are required for complete utilization of the method. Material radioactivity whose intensity may be considered to be independent of time is also treated.
