Fluorescence scintillator screen

The most widely used fiat detector (FD) design is based on a two-level, indirect conversion process of X-rays to light (Granfors et al. 2001 Antonuk et al. 1997 Spahn et al. 2000 Yamazaki et al. 2004 Ducourant et al. 2003). In the first step, the X-ray quantum is absorbed by a fluorescence scintillator screen, e.g., a cesium iodide (Csl) substrate, converting it into visible light. In the second step, this light is received by a photodiode array, e.g., based on amorphous silicon (a-Si), and converted into electrical charge. 

HTS screening is often based on miniaturized cell assays that enable chemical libraries to be screened for molecules that present different biological activities and sometimes-different biological targets using fluorescence, scintillation proximity assays (SPA) and luminescence as detection techniques. 

Other uses are to produce phosphorescence and fluorescence in organic compounds and for scintillation screens on instruments used to detect radiation. Radium salts were used in the past to paint the dials of luminous clock faces that glow in the dark. 

Cesium bromide (CsBr) crystals are used in scintillation counters to detect radiation. The compound is also used to coat the inside of fluorescent screens. 

Cadmium tungstate (CdWO ) is used in fluorescent paint, X-ray screens, and scintillation counters and as a catalyst. It is very toxic when inhaled. 

Cadmium fluoride has similar uses to the zinc halide. Cadmium oxide is used in ceramic glazes the sulfate, as a source of other cadmium compounds and in the radio valve industry the sulfide is important as a yellow pigment for artists, and is used in the paint, soap, glass, textile, paper, rubber and pyrotechnics industries. Cadmium sulfide in admixture with other compounds such as the selenide gives rise to other pigments of value. It is also used in phosphors and fluorescent screens and in scintillation counters. Semiconductors such as CdS... 

Several approaches have been reported for the screening of polymerase activity, for example radioisotope assays such as scintillation proximity assays [56, 57] or fluorescence-based assays [58-61], Most of these assays, however, suffer from use of tedious procedures, the use of radioisotopes, or use of expensive reagents for fluorescence signal generation. A convenient means of online monitoring of DNA polymerase activity has recently been presented by Andreas Marx and Daniel Summerer [62]. Their technique involves a DNA template that forms a stable hairpin structure labeled at two positions ...

Becqnerel discovers radiation from uranium (radioactivity). The intensity of the radiation is measured either through its ionization of air or through the scintillations observed when the radiation hits a fluorescent screen.
