In a preferred embodiment, a method of identifying nuclides, including the steps of: determining spectral continuum via a peak erosion process to render a residual peak spectrum; filtering a standard nuclide library specified by a user to select candidate nuclides; simultaneously fitting calibrations and activities of selected candidate nuclides from the standard library to the peak spectrum using a standard least squares method; calculating statistical significances of optimized nuclide activities and determining shape correlations between optimized candidate nuclide peak spectra and measured peak spectrum with alternative candidates subtracted; and identifying and providing activities of nuclides determined to have sufficiently significant activities and sufficient shape correlations.
