Abstract

In this paper, the ML-EM (Maximum Likelihood Fitting by Expectation Maximization) algorithm was used in deconvolution of continuum gamma ray for HPGe detector. A set of response functions was simulated by using MCNP4C2 code for gamma radiation emitted from point source located at 10.6cm from detector. The source energies varied from 50.1 keV to 1502.1 keV with 2.5 keV step were detected by the 8192 - channel spectrometer. The results of deconvolution for some gamma spectra of Co-60, CS-137, Eu-152 showed that the photopeak areas of the deconvoluted spectra were considerably raised in compare with ones of measured spectra in the same condition.
