Librarian driven analysis with graphic user interface for nuclides quantification by gamma spectra

For a set of a priori given radionuclides extracted from a general nuclide data library, the authors use median estimates of the gamma-peak areas and estimates to produce a list of possible radionuclides matching gamma-ray li ne(s). An a priori determined list of nuclides is obtained by searching for a match with the energy information of the database. This procedure is per formed in an interactive graphic mode by markers that superimpose, on the s pectral data, the energy information and yields provided by a general gamma -ray data library. This library of experimental data includes approximately 17,000 gamma-energy lines related to 756 known gamma emitter radionuclides listed by ICRP. (C) 2001 Elsevier Science B.V. All rights reserved.
