Ceramic Scintillator


A scintillator is a substance that absorbs rays, such as X rays and gamma rays, and makes; them visible to the human eye. Scintillators are used primarily in X-ray computer tomography (CT) and other medical equipment, analytical devices, gamma radiation in nondestructive inspection equipment and devices for detecting radiation leaks. At Hitachi Metals, we have developed high-density, highly functional ceramic scintillators.
