Ag 2 O-MoO 3 -V 2 O 5 -TeO 2 (AMVT) glasses were reported by means of their optical properties such as polarizability, optical transmission, and optical basicity. Moreover, the photon attenuation properties were explored by using FLUKA simulation code for energies up to 1.275 meV. From the optical study, it was noted that the molar polarizability (α Mol. ) decreased from 11.8630 × 10 -24 to 9.4846 × 10 -24 cm 3 , while the optical transmission increased from 0.5498 to 0.5976 as the Ag 2 O concentration increased from 0 to 25 mol%. From the photon attenuation study, the maximum values of µ/ρ (MAC, mass attenuation coefficient) were observed at 0.284 meV. Such those values were 0.1501, 0.1525, 0.1549, 0.1572, 0.1593 and 0.1616 cm 2 /g for AMVT1, AMVT2, AMVT3, AMVT4, AMVT5 and AMVT6, respectively. From the view of practical application, it is found that the HVL values of the AMVT glasses are evidently lower than those of ordinary concrete and RS-253-G18 commercial glass.

“…Such simulations have many advantages compared to the experimental work in terms of the accuracy of the outcomes and saving of time. Moreover, the validation of Geant4 simulation was achieved for several radiation studies and medical applications [28,29].…”

“…With the current aim, we designed the required geometry to simulate the propagation of radiation through the elements involved. Figure 1 depicts the simulation geometry that was adopted, as described in the work of Al-Buriahi et al [23,[27][28][29]. Using C++ language, we defined the elements involved and all the electromagnetic models that are needed to describe the photon interactions with the studied elements.…”

“…The main ingredients of these materials are elements such as Zn, Te, Ba, and Bi, which have several superior physical and chemical properties in relation to other elements in the periodic table. For example, Al-Buriahi and Mann [28] studied the radiation shielding effect of some glass systems containing Te, Nb, and W. Alzahrani et al [29] investigated the radiation protection features of a TeO 2 -Na 2 O-TiO glass system by using the Particle and Heavy ion Transport Code System (PHITS) Monte Carlo code. The findings of the studies show the importance of Te in the ability of the glass sample to shield the radiation.…”

In this work, the Klein–Nishina (K–N) approach was used to evaluate the electronic, atomic, and energy-transfer cross sections of four elements, namely, zinc (Zn), tellurium (Te), barium (Ba), and bismuth (Bi), for different photon energies (0.662 MeV, 0.835 MeV, 1.170 MeV, 1.330 MeV, and 1.600 MeV). The obtained results were compared with the Monte Carlo method (Geant4 simulation) in terms of mass attenuation and mass energy-transfer coefficients. The results show that the K–N approach and Geant4 simulations are in good agreement for the entire energy range considered. As the photon energy increased from 0.662 MeV to 1.600 MeV, the values of the energy-transfer cross sections decreased from 81.135 cm2 to 69.184 cm2 in the case of Bi, from 50.832 cm2 to 43.344 cm2 for Te, from 54.742 cm2 to 46.678 cm2 for Ba, and from 29.326 cm2 to 25.006 cm2 for Zn. The obtained results and the detailed information of the attenuation properties for the studied elements would be helpful in developing a new generation of shielding materials against gamma rays.
