    CdWO4 Scintillation Detector

    Product Details

    Cadmium tungstate CdWO4 (CWO), due to its low intrinsic background and afterglow together with sufficiently high light yield, is the most promising for spectrometry and radiometry of radio nuclides under extremely low activities, and also for computer tomography.

    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 (1215 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.
