    Abstract: The X-ray detection element of an X-ray detector is composed of a fluorescent material having a short afterglow and a high sensitivity to the X-radiation to be detected. For the fluorescent material use is notably made of cerium-activated phosphors such as yttrium phosphors, lanthanum phosphors or lutetium phosphors.

    Abstract: 1498750 Intensifier screens PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 Sept 1975 [1 Oct 1974] 39525/75 Heading H5R [Also in Division C4] A bivalent Eu activated phosphorus of formula Ba 1-x-y-p-g Sr x Ca y Eu p Sm q FX where X is one of Cl, Br or I, and 1#x+y+p+q; 0À20#y#0; 0À20#p#0À001; 0À10#q#0À0001 and 0À50#q/p#0À02. The Sm reduces afterglow as required for X-ray intensifier screen uses with photographic material. Preferably 0À01#p#0À10 and 0À02#q#0À001, the alkaline earth is mainly Ba and X mainly Cl. The examples include specific phosphors. The X-ray film cassette shown includes cover 1, X-ray film 3 with photoemulsion on both sides, and contacting intensifier screens 4 and 5, the former including support 6 (e.g. of paper) with phosphor 7, the latter, support 8 with phosphor 9.
