#research #radiation/detection-and-imaging/scintillator See also: [[Amorphous Selenium]] # Cadmium Tungstate Motivation: Looking into common [[Radiography]] detectors Cadmium Tungstate is a high density, high atomic number (Z) scintillator with a relatively high light yield. The high light output and low afterglow make it an ideal detector to be used with silicon photodiodes in radiation detectors for medical and industrial Computed Tomography (CT) scanning [^1]. [^1]: https://www.advatech-uk.co.uk/cdwo4.html Some issues to note: - CdWO4 scintillator crystals have an intrinsic radioactivity making them unacceptable for some applications - They are susceptible to significant radiation damage, though this is reversiblwe with time and/or annealing
