  • Scintillator compositions of alkali and rare-earth tungstates
    Patent number: 6585913
    Abstract: Scintillator compositions useful for the detection of high-energy radiation, such as X, &bgr;, or &ggr; radiation, contain alkali and rare earth pyrotungstates. In particular, the pyrotungstate is a double tungstate containing an oxide of an alkali metal selected from the group consisting of Na, K, Rb, and Cs and an oxide of a rare-earth element selected from the group consisting of Y, Gd, La, and Lu. The scintillators are characterized by high light output, reduced afterglow, short decay time, and high X-ray stopping power.
    Type: Grant
    Filed: July 30, 2001
    Date of Patent: July 1, 2003
    Assignee: General Electric Company
