ABSTRACT:
A plastic scintillator comprises a polymethylpentene thermoplastic material containing a fluorescent additive. This plastic scintillator material functions at high temperatures with excellent optical properties in the detection of neutrons. The plastic scintillator may also include an energy transfer compound, a wavelength shifter, a solubility enhancer for the polymethylpentene and a decolorizing agent.
