| Model Number: | CRYLINK-CdWO4 Scintillator Crystal | 
| Name: | CdWO4 Scintillation Detector | 
| Light yield (Photon/MeV): | 13000 | 
| Decay time (s): | 12-15 | 
| Peak emission (nm): | 480 | 
| After glow: | 0.1%@6ms | 
| Density (g/cm3): | 7.9 | 
The crystal is transparent and emits light when it is hit by gamma rays and x-rays, making it useful as a detector of ionizing radiation. Its peak scintillation wavelength is 480 nm (with emission range between 380-660 nm), and efficiency of 13000 photons/MeV. It has a relatively high light yield, its light output is about 40% of NaI(Tl), but the time of scintillation is quite long (12~15 s). It is often used in computed tomography. Combining the scintillator crystal with externally applied piece of boron carbide allows construction of compact detectors of gamma rays and neutron radiation.
