Summary: In this study, the radiation shielding properties of certain ceramic materials were experimentally measured and compared with simulation results. Gamma rays with energies of 662, 1173, and 1332 keV were used, generated from 137Cs and 60Co radioactive sources. The experimental measurements were conducted using a gamma spectrometer with a 3'' x 3'' NaI(Tl) detector, while the simulations employed the Monte Carlo method and Gamos 6.2 software to evaluate the linear attenuation coefficients of ceramic materials.

Summary: The current study investigates the radiation shielding, optical, structural, and physical properties of SeTe chalcogenide alloys after incorporating Ag as a chemical modifier. Four different composites labeled as SeTeAg-2, SeTeAg-5, SeTeAg-7, and SeTeAg-10 are irradiated by gamma photons for a wide energy range. The results show that SeTeAg-10 offers excellent gamma photon shielding performance and the SeTeAg composites are rigid materials with preferred chalcogenide glass properties.

Summary: In this study, (S3Sb2)x(S2Ge)100_x chalcogenide glasses with varying concentrations of x (15, 30, 45, and 60 mol%) were investigated for their radiation shielding purposes. The shielding effectiveness of the glass samples was evaluated using Phy-X/PSD simulation codes, with results measured in terms of LAC (linear absorption coefficient), mu (attenuation coefficient), and cm_1 (wave number). Additionally, other crucial parameters such as half-value layer (HVL) and neutron removal cross section were also determined and examined in relation to the SbS concentration in the samples.

Summary: The gamma-ray shielding properties of eight different metallic glasses based on CuxZr100-x: x = 35 (Cu35Zr65) - 70 (Cu70Zr30) were analyzed using Monte Carlo simulations and Phy-X/PSD software. The results showed that the Cu70Zr30 sample exhibited superior attenuation properties among all the studied samples.

Summary: This study developed a computational model for determining Half Value Layer (HVL) and verified its accuracy by comparing the results with data from the National Institute of Standards and Technology. The model, based on a gamma-ray transmission setup simulated using the MCNPX code, showed compatibility with the HVL values obtained from the NIST standard database. The study highlights the usefulness of advanced simulation methods, such as Monte Carlo code, in radiation safety and medical applications.

Summary: Neutrons are important particles emitted by unstable nuclei or nuclear reactions, and their detection and shielding pose challenges due to their lack of charge. Efficient shielding materials are crucial to protect against the hazardous effects of neutrons, which are more dangerous than other radiation types. This study investigated the shielding properties of a container containing polyethylene, barite, lead, and iron, compared through experimental work and calculations using FLUKA code.

Summary: This paper presents a multi-layered shielding approach to reduce radiation exposures in deep space for human spaceships. Different shielding materials were used and analyzed, and the results show that Al + LiH is the most effective combination. The performance of sandwich combinations was also assessed, and Al + LiH + Al performed the best. The dose equivalent was compared between different transport codes.

Summary: This paper designs, optimizes, and analyzes various multi-layer shields for the protection of electronic devices in electron and proton space environments. The results show that the shields outperform aluminum shields in terms of total ionizing dose for proton and electron environments. The construction of a sample shield and comparisons of radiation attenuation coefficient results demonstrate the potential of multi-layer shields for electronic device protection in satellite missions.

Summary: Reinforced composite materials have great potential in radiation shielding due to their lightweight, low cost, high resilience, good mechanical tenacity, and interesting electrical properties. Recent literature has criticized the continued use of lead for radiation shielding due to its drawbacks such as high toxicity, poisoning, lack of stability, heaviness, and hazardous afterlife handling.

Summary: The study aimed to report the gamma ray-neutron attenuation parameters of eight types of vinyl ester pumice (V-P) composites across a wide energy range of 511-2140 keV using MCNPX and FLUKA codes. Results showed that FLUKA code can be used as an alternative technique to determine the attenuation features of vinyl ester composites, and the composite coded as V-P50 can be a competitive candidate for shielding gamma rays and neutrons.

Summary: In this study, linear attenuation coefficients of concretes containing different rates of basalt-magnetite aggregates were measured for gamma energies emitted from radioactive sources. The results showed a linear relationship between the linear attenuation coefficients and the basalt-magnetite ratio. The experimental and theoretical results were found to be compatible, indicating the importance of basalt-magnetite as an aggregate in developing concrete with radiation shielding properties.
