Question

Quizplus · Accepted Answer

a-Se (amorphous Selenium) is not considered a scintillator. Scintillators are materials that exhibit scintillation—the property of luminescence when excited by ionizing radiation. Gadolinium oxysulfide (Gd2O2S) and Cesium Iodide (CsI) are known scintillators used in various applications including medical imaging and radiation detection. Amorphous Selenium, however, is primarily used in digital X-ray imaging detectors and is not a scintillator but a direct detector that converts X-ray photons directly into electrical charge.
