Abstract
This paper reports the fabrication of near UV-, blue-, blue-green-, and green-emitting polyvinyltoluene- and silicone rubber-based solid scintillators with sufficient gadolinium loading to make them attractive for the detection of thermal neutrons. Measurements of characteristic neutroninduced pulse height spectra (containing peaks corresponding to 29 keV conversion electrons coincident with gadolinium atomic x-rays), and the response of these scintillators to gamma rays will be described. In addition, the application of these new materials to measurements of radiation from plutonium and uranium will be discussed.
