Plastic scintillators are sensitive to X-rays, gamma rays, fast neutrons and charged particles.
The scintillation emission of a typical plastic scintillator has a maximum of around 425 nm. Plastic scintillators are characterized by a relatively large light output — typically 25-30% of NaI(Tl) — and a short decay time of around 2 ns. This makes the material suited for fast timing measurements.
The exact emission wavelength and decay time depend on the type of organic activator and on the host material. A large number of different plastic scintillators are available, each for a specific application.
Plastic scintillators are produced in a wide variety of shapes and sizes. Cast sheets are the most commonly used forms. You also can obtain precision thin sheets, rods, annuli, and large rectangular blocks.
