Cadmium tungstate (CdWO4) is a high density, high atomic number scintillator with relatively high light yield, and extreme low after glow. The emission maximum is at 475nm and the total light output is 12 to 15 photons/keV. The light yield relative to NaI(Tl) on a bialkali PMT is 30 to 50%. The high density and stopping power of CdWO4 make it an efficient absorber, particularly for high energy X-ray. It takes only 3mm to stop up to 150keV photons. CdWO4 scintillators has extremely low afterglow property, which is of great importance of fast inspection, especially in the cargo container of customs, while in the X- ray Computerized Tomography (CT) equipment due to its relatively high light output, high density and strong prevention of X ray property, also in the high energy physics because of its strong anti-radiation.
