摘要
A simplified peak fitting technique for the analysis of the overlapped pulse-height spectra of Cs-134 and Cs-137 gamma-rays obtained with a NaI(Tl) scintillation spectrometer was studied. In this analysis, nearly an upper half of 662 keV Cs-137 peak data was employed for fitting of the Gaussian peak using the least squares algorithm. Consistent results were obtained as compared with the reference value of test samples mixed with Cs-134 and Cs-137 standard solutions. (C) 2013 Elsevier Ltd. All rights reserved.
