Triphenyl-p-biphenylyl silane was loaded with 4 boron materials in an attempt to produce a beron loaded silane glass thermal neutron detector. The silane glass was made opaque by homogeneous addition of natural boron, boric acid, or borax. A sandwich scintillator using a natural boron filler was prepared, but thermal neutrons could not be detected. Scintillators loaded with triphenyl-borazole were transparent to visible light and produced a pulse peak for the alpha particle from the neutron-B/sup 10/ reaction. Because of the scintillator's nonlinearity of response with energy, the gamma radiation produced by the neutron source could not be discriminated against. After short periods of exposure to thermal neutrons, internal disintegration of the triphenyl borazole loaded scintillators began. A satisfactory thermal neutron detector was not developed. Although the triphenyl borazole loaded scintillator produced an alpha peak, its gamma discrimination problem and lack of stability under radiation made it unsatisfactory. (auth)
