Plastic scintillator based on polymethyl methacrylate (Review)

One analyzed scintillation features of plastic scintillators based on polymethyl methacrylate with various luminescent additives. It is shown that substitution of octadeuteronapthalin and 1,3-divinyl benzene for napthalin in the mentioned scintillators does not change and substitution of 1,1,3-trimethyl-3-phenylindane improves their scintillation efficiency and optical transparence as well as, thermal, light and radiation stability. One shows possibility to apply n-terphenyl, 2,5-diphenyloxazole, 2-biphenyl-5-phenyl-1,3-oxazole, 2-biphenyl-5(α-naphthyl)-1,3 oxazole, 2-phenyl-5-(4-biphenylyl)-1,3,4-oxadiazole and 2-(4'-tertiary-butylphenyl)-5-(4-biphenyl)-1,3,4-oxadiazole as luminescence activator and n-bis-(o-methylstyryl)-benzene and 1,4-di-(5-phenyl-2-oxazolyl)-benzene as spectrum mixer
