Abstract This work presents a study on the characteristics of the radiation attenuating behavior of oxy-fluoro borotellurite glasses with general formula T eO2–B2O3–LiF–BaO–Bi2O3. The mass attenuation coefficient (MAC) decreases pointedly as the energy goes up from 15 keV–0.15 MeV. The MAC for the tested samples lies within the range 40.032–50.170 cm2/g at 15 keV. We examined the effective atomic number (Zeff), and the results revealed that initially Zeff reaches the maximum values up to around 0.1 MeV and then Zeff decreases and reaches the minimum values between around 1 and 4 MeV. The Zeff lies within the range of 56.11–57.85 (at 15 keV). The Zeff of the tested samples increases with the increasing content of T eO2. The half value layer (HVL) was evaluated, and the effect of TeO2 and the energy on this parameter was discussed. The minimum HVL was reported at 15 keV and varied between 0.00463–0.00226 cm. Keywords Borotellurite glasses · Phy-X/PSD · Shielding · Photon · Half value layer
1 Introduction Recently, with the wide utilizations of radiation sources in different fields, working with these sources with safety and care is absolutely necessary. In modern buildings construction, hospitals, and nuclear power stations, concrete is excessively used to protect from ionizing radiation due to their suitable attenuation ability [1–3]. However, concrete has some unfavorable properties like opacity, and accordingly, it is unsuitable to be used in the optical applications, immobility, bacterial corrosion, and it is non-portable, and hence, it is difficult to transport it from one place to another [4]. Therefore, the researchers in the last few years have * M. I. M.I.Sayyed [email protected] 1

been trying to develop novel shielding materials in order to minimize the hazard of the radiation to acceptable and safer levels in order to protect personnel and workers from harmful radiation. As an alternative, glasses became favorable for utilization in gamma ray protection fields due to their interesting optical and physical characteristics like homogeneity, easy preparation with different techniques, low cost, ability to harbor a vast set of elements and optical transparency [5–8]. Moreover, they can be fabricated by setting the chemical composition and preparation techniques to study the
