Abstract
In this research, glass samples composed of (60-x)B2O3-xBi2O3–30PbO–10Li2O (x = 0, 10, 20, 30, 40 mol%) were prepared for utilize as shields for gamma rays and fast neutrons, using the melt-quenching technique. The studied samples were symbolized as Bi0.0–Bi10–Bi20–Bi30–Bi40 according to the Bi content values. The attenuation characteristics of gamma rays, such as the mass attenuation coefficients MAC and the linear attenuation coefficient LAC of the prepared glass samples, were obtained using Phy-X/PSD and XCOM software programs in the gamma energy range from 0.015 to 15 MeV. In addition, mean free path MFP, half-value layer HVL, effective atomic number Zeff, and buildup factors were also investigated. The results indicated that the addition of Bi2O3 increased the MAC and Zeff and reduced the HVL, MFP, and buildup factors. Also, the results showed that the prepared glass labeled Bi40 has the best shielding properties compared to the other samples. Compared with the concrete shielding such as barite and ordinary concrete, as well as, the RS-360 and RS-253 G18 commercial shielding glass, our prepared glass showed better gamma radiation protection properties. This indicates that our prepared samples can be used as alternative for other gamma ray shields.
