MASS ATTENUATION COEFFICIENT OF [(TeO2)0.7(B2O3)0.3]1-x(BaO)x GLASS FOR ENERGY OF 1 KeV – 100 GeV

Abstract

The gamma shielding parameters of [(TeO2)0.7(B2O3)0.3]1-x(BaO)x glass system in terms of attenuation coefficient, effective atomic number and electron density have been obtained theoretically by WinXCOM programme. The mass attenuation coefficient of all glasses increases with increasing amount of barium oxide, BaO. In present work, the highest composition of BaO in glass system (x = 0.25 mol %) give the highest value of mass attenuation coefficient, μm. Another shielding parameter such as effective atomic number (Zeff) and electron density (Ne) estimated using WinXCOM programme are depending to the barium composition and photon energy.

“…To address this issue, radiation shielding is used to reduce the doses received by soft tissues (6). The most utilised radiation shield in nuclear reactors is concrete because of its strength, adaptable design, low price, and its ability to attenuate gamma-rays (7). However, exposing concrete to gamma-rays for prolonged periods leads to fractures and with high radiation energies the water in concrete can evaporate, which affects the protection efficiency of the concrete (8).…”
