Abstract

In this study, we used Monte Carlo method to simulate each separate component of the gamma scattering spectrum. The gamma rays emitted from a 137Cs source, scatter on aluminum targets and recorded by a NaI(Tl) detector. Based on the distribution characteristics of each scattering component, we propose a new method to analyze scattered gamma spectra. This method was applied for simulated spectra to estimate the material thickness gives good results.

Keywords: gamma scattering Monte Carlo simulation NaI(Tl)
