Abstract
Selected scintillator materials provided in transparent block form for use in systems such as CT scanning systems employ a garnet host material for an activator ion which provides the desired luminescence. The garnet host material preferably includes gadolinium as one of its components in order to provide a transparent host material in bar form which has a high x-ray stopping power (where the radiation to be detected is x-ray radiation). Chromium, cerium and neodymium are preferred activator materials.
