Plastic scintillators are usually based on polystyrene, polyvinyltoluene, or polymethylmethacrylate in which a primary fluorescent emitter, called “fluor”, is suspended. Plastic scintillators can be used as fast-neutron scintillators in combination with photomultiplier tubes or silicon devices. At RMD we are working on several novel plastic scintillator compositions derived from polystyrene. An example of such as novel plastic scintillator is shown in the photograph to the left.
