A design of classifier used for radionuclide fast recognition depend on NaI γ energy spectrum

In order to realize different radionuclide fast detect and automatic recognition, the correlation demodulation theory base on the signal processing and cluster analysis method base on the pattern recognition were applied to detecting and classifying waveform of NaI γ energy spectrum. A classifier which can recognize three types of radionuclide was designed base on the theory and the method mentioned above. The experimentation result demonstrate the classifier realized the purpose of fast and automatic recognizing different radionuclide. (authors)
