“…These calculation methods played an important role in evaluating the potential effectiveness of these materials. Scientists are constantly searching for new and affordable materials that effectively reduce radiation exposure to safe and acceptable levels [6][7][8][9][10][11][12]. Radiation shielding is the implementation of measures for the reduction of radiation intensity to a level that is not harmful to people or the environment, thereby preventing potential direct or indirect damage.…”

This study examined the suitability of several glass compositions as a gamma-ray shielding substance. The compositions tested were of varying ZnO concentrations, specifically (60-x) B2O3 − 10Na2O − 15SiO2 − 5Al2O3 - (x + 10 )ZnO (where X = 5, 10, 15 and 20 mol%). Measurements were performed at energy levels of 0.6642, 1.1776, and 1.3343 MeV radiated from Cs137 and Co60 point sources along with a scintillation detector [NaI(TL)]. We investigated the critical properties related to gamma radiation shielding, determining the effective atomic number (Zeff), electron density (Nel), half-value layer (HVL), linear attenuation (µ) and mass attenuation (µm) coefficients, and mean free path (λ). Our results show that all glass compositions provide adequate protection against gamma radiation at the specified energy levels. The values of µ went up from 0.157 to 0.214 cm− 1 (0.6642 MeV), from 0.119 to 0.160 cm− 1 (1.1776 MeV), and from 0.114 to 0.151 (1.3343 MeV). For samples B1 and B4, the observed HVL values dropped from 4.41, 5.84, and 6.12 cm to 3.21, 4.31, and 4.61 cm at 0.6642, 1.1736, and 1.3343 MeV, respectively. Among the materials tested, prepared glasses show higher shielding capacity compared to regularly used glass and concrete samples. The study highlights these glass compositions' potential as practical materials that can shield gamma radiation.

“…For instance, research has shown that the presence of sodium oxide (Na 2 O) as a network modifier can enhance the mechanical strength, chemical stability, optical transparency, and electrical conductivity of borate-based glasses 12 also it helps in stabilizing the glass so that its shielding properties against radiation is tested without difficulty 13 . Also, the presence of aluminum oxide can boost the properties of borate-based glasses as the ions of Al 3+ join in the network of glass in the form of AlO 4 and/or AlO 6 structural units giving the glasses high resistance capability against radiation as a result of forming robust covalent bonds containing BO 4 and AlO 4 tetrahedral units 14 , 15 . Additionally, the presence of barium oxide (BaO) in the system of glass results in reinforcing the shielding capabilities of the glass network against radiation 16 .…”

Aiming to extend the scope of utilizing glass in radiation shielding, this work investigates the radiation interaction response of a borate-based glass system. Four borate-glass samples of different substituting concentrations of calcium oxide ($$70-x$$ 70 - x )B2O3:$$10$$ 10 Na2O $$:5$$ : 5 Al2O3$$:15$$ : 15 BaO:$$x$$ x CaO were prepared. To assess the shielding performance of the prepared glass samples, a high-purity germanium detector and different radioactive sources (different energies) were used. Via the narrow beam method, the linear attenuation coefficients (LACs) were experimentally measured. So, the transmission factor (TF), the half-value layer (HVL), the tenth value layer (TVL), the mean free path (MFP), and the radiation protection efficiency (RPE) were calculated for all prepared samples. It was observed that the increase of the concentration of calcium oxide in the proposed borate-based glass samples leads to improve their performance in shielding against radiation. At low energy, the RPE of the samples is almost 100%. However, it was observed that as energy of the radiation source increases, the shielding performance of the samples will decrease. High energy dependence was found when calculating TF, HVL, TVL, and MFP. They were increased with the increase of the energy of the incident photons. At 0.662 MeV, the TF values are equal to 79.26, 79.00, 79.72, and 78.43% for BNABC-1, BNABC-2, BNABC-3, and BNABC-4 in the same oder, respectively. The application of the proposed composition of borate-based glass as a transparent shield against low-energy ionizing radiation was highlighted.

We investigated the critical properties related to gamma radiation shielding, determining the effective atomic number (Zeff), electron density (Nel), half-value layer (HVL), linear attenuation (μ) and mass attenuation (μm) coefficients, and mean free path (λ). Our results show that the glasses under examination get denser (from 2.12 to 2.77 g/cm3) as the Zn concentration rises from 15 to 35 mol %. In addition, all glass compositions provide adequate protection against gamma radiation at the specified energy levels. The values of µ went up from 0.157 to 0.214 cm−1 (0.6642 MeV), from 0.119 to 0.160 cm−1 (1.1776 MeV), and from 0.114 to 0.151 (1.3343 MeV).
