Strong resistance to radiation damage and high density CWO Scintillator Crystal
Cadmium Tungstate (CdWO4 or CWO) has high density and atomic number values. Therefore, for CWO, the light output is 2.5 - 3 times higher than that of Bismuth Germanate. Due to low intrinsic background and afterglow and to rather high light output of CWO, the most suitable areas of its application are spectrometry and radiometry of radionuclides in extra-low activities. CWO is the most widely used scintillator for computer tomography. A rather great decay time value (3 - 5 Cls) is a significant feature of CWO which restricts the possibilities of its application in many cases.
Cadmium tungstate (CdWO4 or CWO) is a monoclinic crystal with a wolframite structure and has good comprehensive scintillation properties. The peak scintillation wavelength of CdWO4 crystal is 470 nm , and efficiency of 12000 photons/MeV,when it is hit by gamma rays and x-rays. High luminous efficiency, short afterglow time, large X-ray absorption coefficient, strong resistance to radiation damage, and high material density, so that CdWO4 crystal is widely used in nuclear inspection, γ camera, X-CT, high energy physics, and container inspection, etc. .
