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.
A gamma ray interacting with a scintillator produces a pulse of light that is converted to an electric pulse by a photomultiplier tube (PMT). The PMT consists of a photocathode, a focusing electrode, and 10 or more dynodes that multiply the number of electrons striking at each dynode. A chain of resistors typically located in a plug-in tube base assembly biases the anode and dynodes. Complete assemblies including the scintillator and PMT are available.
The high Z of iodine in NaI(Tl) crystals result in high efficiency for gamma-ray detection. Resolution for a 3-inch diameter by 3-inch length crystal is typically about 7% for 137Cs and slightly worse for larger sizes.
