Inversão Iterativa de Dados de Espectrometria Gama ou Alfa

Abstract

In this work, gamma and alpha-ray spectrometry data are processed by an iterative regression method (Wolberg, 1967) to obtain the activities or yields of radionuclides. This method, applied to Nuclear Geophysics Research, permits the use of either selected energy bands or of all the channels one by one. It may be easily programmed in popular microcomputers and offers many advantages such as the use of mixtures of radionuclides for the calibrations and the treatment of the uncertainties on the measurements and results. The listing of the program written in BASIC, several conclusions about the method and options of nuclear data processing are presented.
