A material that emits optical photons in response to ionizing radiation.



a luminophor in which the flashes of light known as scintillations occur under the action of ionizing radiation. Among the many substances that are scintillators are inorganic crystals, such as zinc sulfide and sodium iodide; organic crystals, such as anthracene and stilbene; solutions of plastics; and inert gases. Scintillators used in scintillation counters should be transparent to their own radiation.
