Summary: The study developed a flexible composite material containing bismuth (III) oxide and hexagonal boron nitride fillers in a silicone rubber matrix to shield both neutron and X/gamma radiations. The mechanical test results showed that the elastic modulus of the optimum sample improved by 4 times compared to the control sample. The composite material exhibited considerable attenuation ratios for both neutron and X/gamma radiations.

Summary: The present study aims to analyze the performance of concrete containing local minerals, barite and cut steel bars, in protecting against gamma-ray and fast-neutron radiation. The results show that using barite as aggregates can increase the radiation shielding capability, as well as the strength and density of specimens. Additionally, using cut steel bars as an additive material significantly enhances the attenuation coefficients of gamma-rays and neutrons.

Summary: This study focuses on the preparation of B4C dispersed epoxy composites for irradiation shielding applications. Samples of different compositions were made and subjected to thermal characterization and irradiation attenuation studies. The results show that the thermal stability of the samples increased due to the intrinsic conductivity of the filler particles, while the shielding performance of the samples increased with an increased addition of B4C at lower energies due to photoelectric absorption.

Summary: This manuscript introduces a design process that combines genetic algorithm with SuperMC to design gradient composite radiation shielding materials. By adjusting the composition of shielding materials according to the changing leaked source, the gradient shielding material with varying composition along the depth is obtained. A genetic algorithm is developed to handle the computational work, including generating required composition, writing input files, executing them on SuperMC, analyzing outputs, and extracting data for designing the gradient shielding material. An example gradient material based on Polyethylene, Tungsten, and Boron carbide is developed and compared to homogenized material and layered shielding structures. The results show the better performance of the gradient shielding material, making it particularly important for mobile compact nuclear applications.

Summary: With the development of aerospace, nuclear technology, and the wide use of nuclear energy, there is an increasing demand for nuclear radiation shielding materials. Rare earth elements have attracted academic attention due to their high neutron absorption cross section and high atomic numbers, and have been applied in research and development of neutron and gamma radiation shielding materials. This paper introduces the application of rare earth materials in radiation shielding and classifies them into rare earth metal-based, rare earth polymer-based, and rare earth glass-based materials. The research progress, potential problems, and prospects of these materials for neutron and gamma radiation shielding are discussed.
