CdWO4 crystal is characterized by high density, high atomic number and relatively high light yield with extremely low decay time.When subjected to x-ray irradiation, the after-glow of CdWO4 is very slow typically less than 0.1% after 3ms, and demonstrate very good resistance. All of these features are significant and make CdWO4 a primary scintillation crystal for x-ray CT and in security inspection.
