A program for qualitative and quantitative analysis of spectra obtained by comparative NAA method is described. It includes peak search, calculation of essential peak parameters, isotope identification and estimation of concentrations and/or detection limits of nuclides, corrected for cooling time and decay during measurement. Corrections for blank samples and peak interference are performed as well. Uncertainties estimation of final results are performed according to the error propagation law. The program is aimed to help an experienced user to calculate the results of analysis but the possibility for automatic mode for routine analysis is provided as well.
