“…Consequently, one may compute the accumulation factor as the ratio of the total exposure to the un-collided dose-response [37]. Additionally, there are two main types of buildup factors that can be listed as the exposure buildup factor (EBF) and the energy absorption buildup factor (EABF) [38,39]. In the framework of the earlier explanation, the smaller buildup factor values may be interpreted as a pattern of dominance against gamma rays since the quantity of un-collided photons in successful shields is small.…”

In this study, a group of heavy metal oxide glasses with a nominal composition of 55B2O3 + 19.5TeO2 + 10K2O + (15−x) PbO + xAl2O3 + 0.5Eu2O3 (where x = 0, 2.5, 5, 7.5, 10, 12.5, and 15 in wt.%) were investigated in terms of their nuclear radiation shielding properties. These glasses containing lanthanide-doped heavy metal oxide were envisioned to yield valuable results in respect to radiation shielding, and thus a detailed investigation was carried out; the obtained results were compared with traditional and new generation shields. Advanced simulation and theoretical methods have been utilized in a wide range of energy regions. Our results showed that the AL0.0 sample with the highest PbO contribution had superior shielding properties in the entire energy range. The effective removal of cross-sections for fast neutrons (ΣR) was also examined. The results indicated that AL5.0 had the greatest value. While increasing the concentration of Al2O3 in samples had a negative effect on the radiation shielding characteristics, it can be concluded that using PbO in the Eu3+ doped heavy metal oxide glasses could be a useful tool to keep gamma-ray shielding properties at a maximum level.

“…Among the newest studied materials, Mg-Zn, PLLA, and tungsten disulfide nanoparticles (WS 2 ) have shown promising outcomes. [256][257][258] Natural polymers (such as collagen, gelatin, silk fibroin, and chitosan) and synthetic polymers (such as PLA, PGA, and PCL) are the most common bioresorbable biomaterials used in bone tissue engineering (such as HA, b-TCP, and BGs). Because of their outstanding bone regeneration potential, scaffolds incorporating additives (such as growth factors) have been used in clinical applications.…”

The alloys with composition:Pb60Sn20CdxZn20-x, where x=0, 5, 10, 15 and 20 mol.% were fabricated at nano-scale as well as bulk scale using the convention melt quench technique. Different characterizations techniques such as Transmission Electron Microscopy (TEM), Field Emission-Scanning Electron Microscopy (FE-SEM) and Energy Dispersive Spectroscopy (EDS) analysis were performed to verify the particle size reduction to nano-scale, surface morphology and elemental composition of Pb60Sn20ZnxCd(20-x) alloy systems. These nano-structured and bulk alloy systems were experimentally investigated and compared for their potential use in the radiation shielding applications. Further, radiation shielding effectiveness against electron beam, proton beam, alpha and heavy carbon ion beams has also been investigated for fabricated bulk alloys using Geant4 simulations. Present theoretical and experimental analysis affirmed that the radiation shielding efficacy gets enhanced for ball-milled PbSnCdZn nano alloy specimens as compared to bulk counterparts.
