  • Detector 1

    Introduction
            
    KHD-1 scintillation detector is a new generation γ-ray measurement device. Combined with lead chamber and Multi-channel Analyzer(MCA) to form Energy Spectrometer, widely used in weak radioactivity analysis field, such as building materials, food, geology etc.

    KHD-1 scintillation detector's advantage including compact structure,easy operation,low background,excellent energy resolution,stable output,high reliability,durability and high detection efficiency.

    Notes:
    1.Detector signal exceeds this value, a truncation will occur.
    2.
    The amplitude of signal is usually less than 1V in spectrum analysis.
    3.
    The value is measured when detector preheated for 10 minutes, the counting rate within 1000, total counting number is  less than 105 in Cs137 peak.
