Abstract:

In the present work, the possibility of creation gamma-ray spectrum, for natural and depleted uranium, by using Monte Carlo simulations has been investigated. Detector efficiency has been calculated for HPGe detector. The broadened signal in the detector caused by electronics of the detector has been simulated by using GEB (Gaussian energy broadening) function. Three standard radioactive sources (Ba-133, Cs-137 and Co-60) have been used to calculate full width at half maximum (FWHM) function parameters. Two Standard Nuclear Material (SNM) samples with different enrichment (Depleted and Natural) in cylindrical aluminum containers have been used to obtain the experimental data. The comparison between the shape of the simulated gamma-ray spectrum and that obtained from experiment indicates a good agreement with a little dispersion for X-rays on spectrum shape formation.
