The gamma radiation from Cs/sup 137/ was used to produce light in organic scintillators. The light pulses were converted to electrical pulses by a photomultiplier tube. The pulses of electrical current were analyzed by three different methods to obtain a suitable method of determining the relative yield of a number of organic phosphors. The pulses were displayed in the form of a differential pulse-height spectrum and an integral pulse-height spectrum. and finally the average photomultiplier tube current was recorded for each phosphor. The differential pulse height spectrum gave the most information and is considered the most reliable method of comparing phosphor yields in that it singles out the forwand-scattered Compton electron. However, the sim ple average- current method is satisfactory in the manufacture of a scintillator where the constituents and method of preparation are varied in maximizing the yield of light. Many complications that arise in comparing scintillators are discussed. These include the spectrum of emitted light, the spectral sensitivity of the photodetector, and the optical transparency and size of the scintillator. (TTT)
