radioactivity log
1.: The principle and processing technique of Gamma energy spectrum is diss-cussed and a physical model and a mathematical model for analyzing the gamma energy spec-trum is established,and radioactivity statistical variation,peak shift and energy graduation which affects analytical precision are solved,Analytical method of the gamma spectrum men-tioned in this paper is a typical case which can be used for data processing in spectrum log-ging or other types of gamma spectra analysis.
