Abstract
The thesis introduces an algorithm to generate customized libraries for automated radio-isotope identifiers using peak searching and library comparison methods. The algorithm has the adaptive feature that could incorporate response curves, such as efficiency-energy curves and full width at half maximum (FWHM)-energy curves, of the detector into the generation process of the library in order to make the generated library to be the best fit for that detector. The suggested algorithm efficiently generates a library that includes centroids and area information of peaks observed in an isotopes’ γ-ray spectrum. The generated centroids are good estimates of the observed peak locations in the γ-ray spectrum and the generated relative area could be taken as reference for the subsequent identification algorithm.
