Radionuclide Analysis of Gamma-Ray Spectra by Stepwise Multiple Regression

摘要

A modification of the usual multiple regression method is described for use in analyzing a gross gamma spectrum from an unknown solution containing many radionuclides. It involves a stepwise multiple regression procedure that sequentially tests the effect of each radionuclide until the spectrum is resolved. The principal advantages over the 'spectrum stripping' or conventional multiple regression are that the procedure: (a) requires no a priori assumptions about the radionuclide content of the solution, and (b) utilizes the information in all of the channels simultaneously.
