Ionizing radiation/charged particles shielding capacity of high density bismuth tellurite based glasses: (100-x)TeO2+xBi2O3 with x = 5(TB5), 8(TB8), 10(TB10), 12(TB12), and 15 (TB15) mol% have been examined. New Phy-X/PSD software has been applied to achieve this aim. The gamma radiation shielding parameters such as mass/linear attenuation coefficients (MAC/LAC), half value thickness (HVT), effective atomic number/electron density (Zeff/Neff) and mean free path (MFP) were estimated for thirteen (13) energies in the range of 0.2835–2.506 MeV associated with 60Co, 137Cs, 131I, and 22Na sources. Comparatively, the obtained values revealed that (MAC/LAC)TB5

In the present study, nanocomposites with different ratios of NiO and Co3O4 (x = 0.3, 0.5, and 0.7) have been prepared via microwave oven and characterized using XRD. FLUKA code has been used to estimate the values of the mass attenuation coefficient (μm) for all samples. From the measurement, we found that when the thickness of the samples increases, the gamma transmission values decrease. Besides, the μm values increase as the Co3O4 content increase from 0.3 to 0.7%. At selected photon energy, the HVL, TVL, and MFP values decrease with increasing Co3O4 concentrations. At low energies (0.1–0.5 MeV), the linear decreasing trend in MAC values indication that photoelectric effect (PEA) (∝1/E3.5) dominance over this region. Afterward, at medium energy regions (0.5–1.33 MeV), the decrements in MAC values are insignificant as the Compton scattering (CS) (∝1/E) phenomenon dominates. As a conclusion, CoNi3 has superior effectiveness as a shielding material.
