Cadmium tungstate (CdWO4 or CWO) is monoclinic crystal with excellent comprehensive scintillation properties. The emission peak of CdWO4 crystal is around 480nm (with emission range between 380-660 nm), with extremely low afterglow, good radiation resistance.  It shows high density, with a high light output of 13000 photons/MeV. Which has been widely used in the security inspection, medical X-CT, Positron emission tomography (PET) and other industries. The combined application of CdWO4 crystal and B4C can form a compact γ- ray and neutron radiation detector. It can also be applied as a scintillation screens for α and β particles.
