Comparison of Various Spectra Methods Used in Vehicle-Based Nai(Tl) Spectrometry Survey
Abstract:
Vehicle-based NaI(Tl) spectrometry is widely used in searching for lost sources. There are several spectra methods can be used to detect abnormal radiation caused by manmade nuclides among a sequence of spectra. In order to test which method has the highest sensitivity, an experiment was done, and three commonly used spectra methods were used to process the acquired spectra. The result indicated that: the noise adjusted singular value decomposition method is more sensitive than other methods. Finally, its drawback was also discussed.
