“…Nowadays, with the advancement of nuclear technology in various areas of science (e.g., industries, nuclear reactors, and especially medical centers), humans, plants, and animals are exposed to neutrons, heavy particles and ions, and gamma radiation. Therefore, research on protecting humans, plants, and animals from serious hazards of those radiations has been the subject of intense research 1 , 2 . Over the past decades, various shielding materials, e.g., wide range of stones, concretes, alloys, polymers, and glasses have been developed and used as materials with appropriate mechanical, optical, and shielding properties for protecting from radiation dangers 3 – 7 .…”

Regarding to their unique physical and mechanical features, glasses and glass–ceramics are suitable materials for shielding purposes. The present study evaluates the shielding properties of the CaF2–CaO–B2O3–P2O5–SrO–Ta2O5 glass system using Monte Carlo GEANT4 and MCNPX codes for X-ray radiations with an energy range of 20 to 100 keV. MAC values of the Ta0, Ta1, Ta2, Ta2.5, and Ta3 samples of the CaF2–CaO–B2O3–P2O5–SrO–Ta2O5 glass were computed using Phy-X/PSD, GEANT4, and MCNPX codes and compared. According to the results, the programs have good compatibility with each other. For instance, in the energy of 40 keV and for the Ta2 sample, GEANT4 and MCNP codes are 1.445765406 and 1.517801204 cm2/g, respectively, indicating 7.419529525 and 2.829628418% differences with 1.562 cm2/g obtained using the Phy-X/PSD software. According to recent estimations, the Ta3 sample of the CaF2–CaO–B2O3–P2O5–SrO–Ta2O5 glass system can be selected as the best shield compared with the other samples.

This study aims to investigate the impact of CeO2 content and particle size on the radiation shielding abilities of polydimethylsiloxane, also known as silicon rubber (SR). We prepared different SR samples with 10, 30, and 50% of micro and nano CeO2 and we measured the linear attenuation coefficient (LAC) for these samples. We found that the LAC of the SR increases by increasing the CeO2 and all prepared SR samples had higher LACs than the pure SR. We examined the effect of the size of the particles on the LAC and the results demonstrated that the LAC for nano CeO2 is higher than that of micro CeO2. We investigated the half value layer (HVL) for the prepared SR samples and the results revealed that the SR with 10% micro CeO2 had a greater HVL than the SR with 10% nano CeO2. The HVL results demonstrated that the SR containing nanoparticles had higher attenuation effectiveness than the SR with micro CeO2. We also prepared SR samples containing CeO2 in both sizes (i.e., micro and nano) and we found that the HVL of the SR containing both sizes was lower than the HVL of the SR with nano CeO2. The radiation protection efficiency (RPE) at 0.059 MeV for the SR with 10% micro and nano CeO2 was 94.2 and 95.6%, respectively, while the RPE of SR containing both sizes (5% micro CeO2 + 5% micro CeO2) was 96.1% at the same energy. The RPE results also indicated that the attenuation ability was improved when utilizing the micro and nano CeO2 as opposed to the micro CeO2 or nano CeO2 at 0.662, 1.173, and 1.333 MeV.

The radiation shielding abilities of europium oxide doped bismuth tellurium barium zinc borosilicate glasses were investigated. Five glass samples, denoted as BiTeEu-0, BiTeEu-1, BiTeEu-2, BiTeEu-3, and BiTeEu-4, were assessed to determine their effectiveness in shielding against incident photon energies of 356, 662, 1173, and 1332 KeV. The glass composition was 12B2O3 - 16SiO2-xEu2O3-(40-x)TeO2-12Bi2O3-12ZnO-8BaO, where x ranged from 0 to 4 mol%. In order to assess the effectiveness of the prepared glass systems as radiation shields, several numerical parameters were experimentally measured. These parameters included the linear attenuation coefficient (LAC) and other relevant factors. In order to validate the experimental setup, the LAC values were determined theoretically using WinXCOM software. This provided an opportunity to compare the experimental results with the theoretical values, allowing for the accuracy of the measurements to be assessed. The theoretical and experimental LAC values were identical, indicating the reliability of the experimental setup. A declining trend was found for the value of mean free path (MFP) as - BiTeEu-0 (0 mol % Eu2O3)> BiTeEu-1 (1 mol % Eu2O3)> BiTeEu-2 (2 mol % Eu2O3)> BiTeEu-3 (3 mol % Eu2O3)> BiTeEu-4 (4 mol % Eu2O3) from energy 0.06 MeV to 1.332 MeV.
