Study of nuclide identification algorithm based on matching the characteristic peaks
Abstract: With the development of nuclear energy, nuclear pollution and nuclear terrorist threat is becoming more and more serious, so this article introduces the structure and the development of the portable spectrometer. And the energy spectrum analysis of spectrum stabilization, smoothing, peak search method. Study on theenergy spectrum of nuclide identification analysis and the introduction of the key.
Nuclide identification mainly includes the following methods: using the method ofanastomosis reliability discriminant coherent nuclide; spectrum stripping method;inverse matrix; the first estimate can be measured with radionuclide samplealgorithm
This paper mainly discusses the simple algorithm can know in advance the testedspecies coherent nuclide contained in the sample. A brief description of thesystem scale spectrometer.
