Description
  • 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 10
