WebPlastic 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. Webreflector surrounding the core. This is mainly due to large amounts of graphite surrounding this irradiation channels and absence of neutron sources in the vicinity of the irradiation channel.
