In this paper, a variety of methods are used to perform peak-seeking analysis on the mixed energy spectrum generating from 60Co, 137Cs and 226Ra, the effects of each peak-seeking method are compared for this complex energy spectrum. In this comparative experiment, the results show that the morphological energy spectrum peak-seeking method is more suitable for the energy spectrum from a mixture of multiple radionuclides. %K Radionuclide %K Energy Spectrum %K Peak-Seeking %U http://www.oalib.com/paper/5437372
