“…Table 4 shows the mass density (ρ m), linear attenuation coe cient (µ L ), mass attenuation coe cient (µm), half-value layer (HVL), and tenth-value layer (TVL), by using the Cesium source (Cs 137 ) and an energy of 663 keV for (3,6,9,12) mm shielding thickness of each Pb-NPs loading. The results show that the mass density, linear attenuation, and mass attenuation coe cients increase with increasing loading levels of Pb-NPs in SBR composites.…”

This research aims to prepare a polymeric composite material from styrene butadiene rubber (SBR) reinforced with lead nanoparticles (Pb-NPs) to make protective shields from gamma rays to protect the healthy tissues of cancer patients while receiving treatment and to protect workers in nuclear reactors and malignant tumors centers. The basic principle is to attenuate the gamma-ray photons emitted by the Cesium source (Cs137) with an energy of 663 keV. The basis for studying the shielding properties after adding the 50,100,150,200, and 300 phr lead nanoparticles. The results showed increased mass density, linear attenuation, and mass attenuation coefficients by 743.712%, 390.47%, and 180.95% with increasing loading levels of Pb-NPs in SBR composites up to 300 p h r. At the same time, the half-value and tenth-value layers decrease by 64% compared with the control sample (without Pb-NPs). The field emission scanning electron microscope (FE-SEM) images show good dispersion and homogeneity of these particles in the rubber matrix, and few agglomerations occur with increasing lead loading. The swelling ratio decreased by 199%, increasing the volume fraction of rubber and cross-link densities by about 7.1% and 14%, respectively. the addition of lead nanoparticles leads to enhanced crystalline properties.

“…However, lead has the highest linear attenuation coe cient when using gamma rays or x-rays [10]. Therefore, the SBR compound was reinforced with TiO2 because it can protect against gamma rays, facilitate photocatalytic activity, generate reactive oxygen species [11], and enhance electrical and optical properties [12].…”

Several radiation shielding parameters for (75-x)B2O3-10TeO2-13SrCO3 -2ZnO-xPbO glasses were evaluated between 0.284 and 1.333 MeV. The PbO content in the glass has a positive relationship with the density of the glasses, leading to BTSZP0, the glass with no PbO, having the smallest density, while BTSZP5, which has 40 PbO mol%, has the greatest density. Radiation shielding parameters such as mass attenuation coefficients and other related factors were computed, and relationships between PbO content, energy, and density are graphed. Linear attenuation coefficient (LAC) is reported and we evaluated the impact of density on the LAC values. By adding more PbO atoms, the density of the samples increased, leading to a higher LAC. The BTSZP0 sample has the highest HVL at all tested energies, with the BTSZP5 sample having the lowest HVL. Mean free path (MFP) has an inverse relationship with the density of each sample but increases with greater incoming photon energy. The effective atomic number (Zeff) values peak at low photon energies and rise significantly with increasing PbO content. The MFP and TVL of the BTSZP glasses are compared against previously tested glass samples at a set energy, and the values demosntrated the effectiveness of the BTSZP glasses.

“…A low order of the photo-electric phenomena is present at energies above 300 keV, as evidenced by the observation of a few orders of increase in EAN at that energy. Because Y 3+ ions have replaced Ho 3+ ions, there has been a significant increase in the EAN values of the glasses as the concentration of Ho 2 O 3 has increased [32].…”

The goal of the ongoing research was to create resources that were mechanically durable, thermally luminous, and radiation-shielding. In this manner, we intended to synthesize lead borate glasses containing functional groups for yttrium and holmimum. Ho2O3 doped glasses, which are typically used for luminescent purposes, will also be used to investigate the thermoluminescence characteristics under gamma radiation. XRD, SEM, EDX, and DTA techniques are used to examine the samples' structure, chemical analysis, and thermal characteristics. To assess the samples' micro-hardness, the test sample's ultrasonic velocities are measured.The mass attenuation coefficient and order of radiation protection ability are shown by the radiation shielding characteristics of samples. It should be highlighted that Holmium ions alone are responsible for the shielding behaviour. The TL characteristics of the samples were examined at gamma irradiation doses of 5, 10, and 25 kGy. Irradiation increases the TL Intensities that have been observed. The findings show that Ho2O3 is the only factor contributing to the TL phenomenon, and test samples exhibit substantial TL activity. Additionally, samples were examined using the DTA technique for changes in thermal stability. Which also implies that changes in thermal stability are solely dependent on holmium concentration. Overall, the results showed that Y(20-x)Pb10B70:Hox glasses are effective TL materials and strong radiation shielding resources with low thickness values.
