Using the pulse-echo approach, the structure of the glass series was meant to be (100−x). 65.95 P 2 O 5 - 24.47 PbO - 9.58 ZnO - x Nd 2 O 3 (where x = 0, 0.46, 0.92, 1.38, and 2.71 mol. percent). We looked at the structure of the suggested glasses as well as the ultrasonic mechanical and shielding capabilities of such glasses. The obtained findings were analyzed and interpreted in terms of alterations of all measured and estimated characteristics with the addition of Nd2O3 content to the internal structure of the glasses that were researched. The mechanical properties were found to be enhanced with Nd2O3. To provide us with a quantitative analysis of the outcomes of the experiment, we made use of the bond-compression model as well as the Makishima-Mackenzie model. Both of these models provide some insight into the structure of the produced glasses. Glass samples were found to have an increase in both their ultrasonic velocity and their Debye temperature. As the amount of Nd2O3 was increased, there was a discernible rise in both the density and the molar volume of the glass system. For all Nd-zinc lead phosphate glasses, the maximum values for MAC were achieved at energies of 15 keV, while the minimum values were obtained at 6 MeV. In addition to this, the HVL of this glass was much lower than that of regular concrete and RS-360. Based on these results, it seems that the current glass absorbs photons better than the other two materials. As a result, it may be useful as a thinner photon shield, especially when the amount of space available is limited. [ABSTRACT FROM AUTHOR]

A series of barium, lead borate (BaLB) glasses with chemical composition x ZnO–(30-x) BaO–30PbO–40B2O3, x variety 0 ≤ x ≤ 20 mol % has been prepared and synthesized by a conventional melting method. The structural analysis has been performed using FT-IR techniques. FT-IR confirmed that BO3, BO4, PbO6, and ZnO4 are structural units. The optical absorption spectra have been studied before and after gamma irradiation. The radiation shielding parameters were evaluated experimentally and theoretically using the XCOM program within the energy range 0.662 MeV–1.333 MeV. In addition, the shielding parameter values investigated using XCOM software are in a good agreement with experimental results. These parameters indicate that the prepared samples possess better shielding properties than ordinary concrete. [ABSTRACT FROM AUTHOR]
