Abstract

The going study aims to investigate the charged-uncharged particles' shielding performance of the (70 - x) CRT-30K(2)O-xBaO glass system for x = 0-20 mol% via the MCNPX simulation, analytical calculations, Phy-X: PSD, and SRIM software. For this purpose, three types of glasses coded as G-C1, G-C2, and G-C3 are irradiated by the Cf-252 neutron source. Applying Watt Fission Distribution (WFD) and Doppler Effect (DE), the neutron-gamma photon spectra are extracted and the obtained results are shown graphically. The outcomes reveal that G-C1 can better shield neutrons among the rest of the chosen samples and a strong linear relationship is found between equivalent absorbed dose rate and Fast Neutron removal Cross Section (FNRCS; cm(-1)) with R-2 = 0.99225. In addition, by increasing the density from 2.8232 g.cm(-3) for sample coded as G-C1 to 3.2266 g.cm(-3) for the sample coded as G-C3 an ascending order of (LAC)(G-C1) < (LAC)(G-C2) < (LAC)(G-C3) is monitored and the best gamma photon-shielding competence is recorded for G-C3. Moreover, the glass samples' Transmission Factor (TF) and Radiation Protection Efficiency (RPE) are evaluated and discussed in detail.
