Monte Carlo Simulation for Estimating of Gamma Ray Attenuation of Nano - Mercuric Oxide into Nano - Bentonite Samples
A. M. Ali, W. A. Ghaly
Abstract: The present work presents estimation of the gamma rays and neutrons attentions for samples of Nano - mercuric oxide (N - HgO) into Nano - Bentonite (N - Bent) based on using (100 - x% N - Bent x% N - HgO, x = 10, 20, 30, and 40 wt %). A comparison study between experimental results and simulation is demonstrated. MCNP code is used to simulate the penetration of gamma rays and neutrons through the samples. MCNP code and Phy - X/PSD software programs were also used to calculate some parameters for shielding such as effective atomic number (Zeff), mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), tenth value, half value layers (TVL, HVL), mean free path (MFP) and effective electron number (Neff) of the samples. The samples under investigation are of densities ranging from 2.447 g/cm3 to 3.647 g/cm3. Both results of Phy - X/PSD and MCNP are compared to experimental results from papers containing the same samples under study. MCNP and Phy - X/PSD software programs show good agreement in the studied energy range. Sample 5 - Hg shows better shielding properties than the other samples.
