The scintillation properties between a plastic scintillator and the generally used inorganic scintillators such as thallium-doped caesium iodide (CsI(Tl)) are quite different. The lower effective atomic number of the plastic scintillator makes the stopping power and light yield relatively lower than the inorganic scintillators ( 1 ) .

A scintillator is a material that exhibits scintillation—the property of luminescence, when excited by ionizing radiation.Luminescent materials, when struck by an incoming particle, absorb its energy and scintillate, (i.e. re-emit the absorbed energy in the form of light).
