“…We observed admissible consistency between the experimental and theoretical LACs and MACs of our samples, and the measured and calculated values show changes with the change of the polymer type used to improve the gamma radiation shielding materials. For the same purpose, the HVL, TVL, MFP, and RPE values of the crosslinked PS-b-PEG block copolymers-BN-PbO nanocomposites were investigated in the relevant photon energy region for the gamma-ray attenuation characteristics [ 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 ]. These results are a very important marker of the radiation shielding characteristic of the material concerned.…”

This work aimed to research the efficiency of gamma irradiation and shielding characteristics on the lead oxide (PbO) doped the crosslinked polystyrene-b-polyethyleneglycol (PS-b-PEG) block copolymers and polystyrene-b-polyethyleneglycol-boron nitride (PS-b-PEG-BN) nanocomposites materials. The crosslinked PS-b-PEG block copolymers and PS-b-PEG-BN nanocomposites mixed with different percentage rates of PbO were used to research gamma-ray shielding characteristics. The synthesis of the copolymer was done by emulsion polymerization methods. The characterization and morphological analyses of irradiated samples were explored handling with the Nuclear Magnetic Resonance (NMR), Fourier Transform Infrared Spectroscopy (FTIR), Gel Permeation Chromatography (GPC), Thermogravimetric Analysis (TGA), and Scanning Electron Microscope (SEM) methods. The gamma-rays that were emitted from the E 152u source were observed with a High Purity Germanium (HPGe) detector system and examined with a GammaVision computer program. Our samples, including the different percentage rates of the PS-b-PEG (1000, 1500, 10,000), BN, and PbO, were irradiated in various gamma-ray photon energy regions (from 121.78 keV to 1408.01 keV). Then, Linear-Mass Attenuation Coefficients (LACs-MACs), Half-Tenth Value Layer (HVL), Mean Free Path (MFP), and Radiation Protection Efficiency (RPE) values of the samples were calculated. Via crosschecking the acquired data from samples with and without PbO and BN, it was observed that, if the different percentage rates by weight nano-powder of PbO and BN are added in the polymer mixture, it can be used as a convenient shielding material against gamma rays.

“…Consequently, the T80 sample’s EABF minimum values were included. Finally, we have compared the gamma-ray shielding properties of the T80 sample with different types of shielding materials, such as TZNG-A [ 13 ], TZNG0.5 [ 14 ], Gd10 [ 15 ], Gd15 [ 16 ], PNCKM5 [ 17 ], C25 [ 18 ], SCNZ7 [ 19 ], Ordinary Concrete (OC), HSC, ILC, BMC, IC, and SSC [ 20 ]. This study sought to understand the overall performance of the T80 sample, in terms of the T 1/2 values necessary to attenuate incoming gamma-ray photons from 0.015 to 15 MeV.…”

“…Therefore, effective removal cross-section values of T60, T70, T80, S60, S70, and S80 glasses against fast neutrons (Σ R ) were determined. Detailed information about the studied parameters can be found in THE literature elsewhere [ 11 , 12 , 13 , 14 ]. In addition to determining parameters, HVL values of the T80 sample were compared to those of many shielding glasses available in the literature, and various types of concrete.…”

The radiation shielding characteristics of samples from two TeO2 and Sb2O3-based basic glass groups were investigated in this research. TeO2 and Sb2O3-based glasses were determined in the research as six samples with a composition of 10WO3-(x)MoO3-(90 − x)(TeO2/Sb2O3) (x = 10, 20, 30). A general purpose MCNPX Monte Carlo code and Phy-X/PSD platform were used to estimate the radiation shielding characteristics. Accordingly, the linear and mass attenuation coefficients, half value layer, mean free path, variation of the effective atomic number with photon energy, exposure and built-up energy factors, and effective removal cross-section values were determined. It was determined that the results that were produced using the two different techniques were consistent. Based on the collected data, the most remarkable findings were found to be associated with the sample classified as T80 (10WO3 + 10MoO3 + 80TeO2). The current study showed that material density was as equally important as composition in modifying radiation shielding characteristics. With the T80 sample with the greatest density (5.61 g/cm3) achieving the best results. Additionally, the acquired findings were compared to the radiation shielding characteristics of various glass and concrete materials. Increasing the quantity of MoO3 additive, a known heavy metal oxide, in these TeO2 and Sb2O3-based glasses may have a detrimental impact on the change in radiation shielding characteristics.

In this work, shielding parameters of LAS (lithium-aluminum-silicate) Li2O-Al2O3-SiO2 glass samples have been reported with the help of the WinXCom code, a Windows version of the XCOM database. The effect of increasing P2O5 concentration on the shielding parameters has been examined in the used Li2O-Al2O3-SiO2 glass samples. The shielding effectuality of the materials for gamma-ray can be interpreted with the help of several different attenuation parameters which plays key role in understanding the shielding capabilities of the material. The mass attenuation coefficient, defined by = / , is the most basic coefficient used to calculate the shielding parameters. These parameters are the mean free path (MFP), half value layer (HVL), tenth value layer (TVL), effective electron number (Ne) and equivalent atomic number (Zeq). The exposure buildup factor (EBF) and GP fitting parameters are also calculated by the method of logarithmic interpolation using Zeq of a Li2O-Al2O3-SiO2 glass system. The EBF values for Li2O-Al2O3-SiO2 glass samples show an inverse relation with Ne. Further, P1 (least Ne) offers maximum values of EBF and P6 (highest Ne) offers minimum EBF values. The change in different shielding parameters for the selected glasses was interpreted by considering three interactions with the substance (Photoelectric effect, Compton scattering and pair production). The obtained results show that the strongly depends on the photon energy, chemical composition and density of the shielding materials. It is clear to see that P6 glass sample having the highest P2O5 concentration is the most effective glass sample among the other glasses of Li2O-Al2O3-SiO2 system in nuclear radiation shielding ability.
