Cadmium Tungstate (CdWO4) is a scintillation crystal with extremely low afterglow, good radiation resistance, high density and high Z value, low decay time also with relatively high light output.
CdWO4 scintillators was produced by using the Bridgman technique since 2011, with the maximum crystal boule size at ∅ 80 mm x 200 mm, which can be manufactured into the target sizes, besides the single crystals, we also have the capability to fabricate it into linear or 2 dimensional array used in the X ray security inspection systems.
CdWO4 scintillators is characterized by high density, high atomic number and relatively high light yield with extremely low decay time. and the afterglow of CdWO4, when subjected to x-ray irradiation, is very slow typically less than 0.1% after 3 ms, and demonstrate very good resistance. All of these features are significant and make CdWO4 a primary scintillation crystal for X ray computed Tomography(X-CT) and in security inspection.
