          Abstract

          Radiation is an important phenome and has been used in many different fields since its discovery. Although there are different types of radiation, neutron is one of the most interesting types as it is an uncharged particle. This character made neutron is more dangerous radiation types than others and thus protection from neutron effect requires more care. In this paper neutron attenuation coefficients of B2O3 reinforced composite have been investigated using Phy-X/PSD software.

            An Investigation on Radiation Shielding Properties of Borosilicate Glass Systems

            The aim of this research is to examine the radiation shielding properties of 5B2O3-40SiO2-(55-x)Al2O3-xBaO (BSABa-x) glass systems, which are containing barium and aluminum oxide added to borosilicate glasses, with varying from 25 to 34 weight fractions. Shielding parameters, such as linear attenuation coefficients (LAC), mass attenuation coefficients (MAC), mean free path (MFP), effective atomic number (Zeff), effective electron density (Neff), half-value layer (HVL), tenth-value layer (TVL), effective atomic weight (Aeff), exposure buildup factors (EBF) and energy absorption buildup factors (EABF) enable us to obtain information about the radiation shielding power of composite glass material groups. Therefore, the mass attenuation coefficients (MAC), for the 0.015–15 MeV gamma-ray energies are obtained by using the Py-MLBUF online software to determine photon shielding parameters of BSABa-x glasses. The results are shown that the glass which contains higher BaO concentration has higher mass attenuation coefficients. BSABa-34 glass has the highest MACs, ranging from 0.111 cm2/g to 90.400 cm2/g, while BSABa-25 glass has the lowest values, ranging from 0.099 cm2/g to 69.000 cm2/g. The BSABa-34 glass with the highest BaO contribution has the thinnest MFP and HVL values. In addition, photon buildup is minimized by adding BaO to the BSABa-x glasses. Accordingly, we can conclude that adding BaO to aluminum borosilicate glasses at increasing rates, improves nuclear radiation resistance properties.

              A detailed investigation on highly dense CuZr bulk metallic glasses for shielding purposes

              Gamma-ray shielding properties of eight different metallic glasses based on Cu x Zr100- x : x = 35 (Cu35Zr65) − 70 (Cu70Zr30) were determined using Monte Carlo simulations and Phy-X/PSD software. A typical gamma-ray transmission setup has been modeled in MCNPX Monte Carlo code. The general trend of the linear attenuation coefficients ( μ ) was reported as ( μ ) Cu35Zr65 (MFP,HVL) Cu40Zr60 > (MFP,HVL) Cu45Zr55 > (MFP,HVL) Cu50Zr50 > (MFP,HVL) Cu55Zr45 > (MFP,HVL) Cu60Zr40 > (MFP,HVL) Cu65Zr35 > (MFP,HVL) Cu70Zr30 for all photon energy range. The Cu70Zr30 sample showed maximum values of both the effective conductivity ( C eff ) and effective electron density ( N eff ). In addition, the Cu70Zr30 sample has minimum exposure and energy absorption buildup factor (EBF and EABF) values at all studied gamma-ray energies. The results revealed that the Cu70Zr30 sample has superior attenuation properties among all studied samples.
