“…It is also worth mentioning that several transition metal borides investigated in this study outperform many extensively used neutron shielding materials. The calculated fast neutron removal cross-section values of the ReB 2 , WB 2 , TaB 2 , HfB 2 , MoB 2 , NbB 2 , ZrB 2 , and TiB 2 are significantly higher than those of lead (0.118 cm −1 ), B 4 C (0.141 cm −1 ), NiO and PbO added borate glasses (0.111 cm −1 ), concrete (0.094 cm −1 ), graphite (0.077 cm −1 ), and paraffin (0.077 cm −1 ) [30,35,60].…”

“…Intensive efforts have been made in developing new generation glass and glass-ceramic materials, especially for such applications [29]. The effectiveness of various oxide compounds, including ZnO, CuO, Dy 2 O 3 , Al 2 O 3 , V 2 O 5 , SiO 2 , CdO, SrO, Bi 2 O 3 , CoO, and Nd 2 O 3 , as gamma-shielding additives in glass compositions has been intensively investigated due to their high molecular weight and ability to participate in the glass network structure [28,[30][31][32][33][34][35][36][37].…”

All-in-one radiation shielding is an emerging concept in developing new-generation radiation protection materials since various forms of ionizing radiation, such as neutrons and gamma rays, can occur simultaneously. In this study, we examine the ability of transition metal borides to attenuate both photon and particle radiation. Specifically, fourteen different transition metal borides (including inner transition metal borides) are selected for examination based on their thermodynamic stabilities, molecular weights, and neutron capture cross-sections of the elements they contain. Radiation shielding characteristics of the transition metal borides are computationally investigated using Phy-X/PSD, EpiXS and NGCal software. The gamma-ray shielding capabilities of the transition metal borides are evaluated in terms of the mass attenuation coefficient (μm), the linear attenuation coefficient (µ), the effective atomic number (Zeff), the half-value layer (HVL), the tenth-value layer (TVL), and the mean free path (MFP). The mass and linear attenuation factors are identified for thermal and fast neutrons at energies of 0.025 eV and 4 MeV, respectively. Moreover, the fast neutron removal cross-sections (∑R) of the transition metal borides are calculated to assess their neutron shielding abilities. The results revealed that borides of transition metals with a high atomic number, such as Re, W, and Ta, possess outstanding gamma shielding performance. At 4 MeV photon energy, the half-value layers of ReB2 and WB2 compounds were found as 1.38 cm and 1.43 cm, respectively. Most notably, these HVL values are lower than the HVL value of toxic Pb (1.45 cm at 4 MeV), which is one of the conventional radiation shielding materials. On the other hand, SmB6 and DyB6 demonstrated exceptional neutron attenuation for thermal and fast neutrons due to the high neutron capture cross-sections of Sm, Dy, and B. The outcomes of this study reveal that transition metal borides can be suitable candidates for shielding against mixed neutron and gamma radiation.

“…The projected range (RP) is a significant parameter for determining nuclear radiation shielding and interactions with materials [14]. The RP is assumed as the distance traveled by the particle within the medium previous to lose all of its energy [15]. The RP of charged particles can be written as 0 1 ()…”

In this study, the resistance of the Rhenium-Boron (Re-B) based alloys against the transmission of charged particles such as electron, proton, alpha, carbon and oxygen was investigated using the stopping power as the characterizing quantity. For this, the collision, radiative/nuclear, total stopping powers and projected range of the charged particles in the Re40-B60, Re50-B50, Re58-B42 and Re60-B40 alloys were calculated using the ESTAR, and the the Stopping and Range of Ions in Materials (SRIM) Monte Carlo code. It was found that the stopping powers of the heavy charged particles tended to decrease with increasing the rhenium concentration. These results suggest that the boron element is more suitable for heavy charged particle shielding materials compared to rhenium element.

“…The development of materials that can effectively attenuate ionizing radiation has been made possible by the development of polymer composites. [13][14][15][16]. Because polymers are lightweight, durable, flexible, and have superior physical, mechanical, and high attenuation properties, they are promising alternatives to traditional radiation shielding materials [16,17].…”

In this study, polymer nanocomposite materials based on polypropylene and iron nanoparticles are evaluated for their gamma-neutron shielding capabilities. The chemical composition of these materials is (100-x) PP-Fex, (where x = 0.1, 0.3, 0.5, 1, 2 and 5 weight percent). Using the Geant4 Monte Carlo code, the mass attenuation coefficient(MAC), a crucial parameter for studying the gamma-ray shielding capabilities, was determined for the proposed polymer samples in the photon energy range of 30-2000 KeV. The results were compared to those predicted by the EpiXS programme. The values of the Geant4 code and the EpiXS software were both found to be in excellent agreement. The linear attenuation coefficients, electron density, effective atomic number, and half value layer for all the concerned samples were then determined for each sample using the mass attenuation coefficient values. Additionally, the polymer samples' neutron shielding properties were evaluated by estimating both the fast neutron removal cross-section and the mean free path of the fast neutron in the energy ranging between 0.25-5.5 KeV. The findings show that as the polymer sample's Fe nanoparticle content rises, the PP-Fe polymer samples' gamma-ray shielding efficacy changes. Among the examined glasses, the PP-Fe5 polymer sample offers the best gamma-ray shielding ability. Finally, the PP-Fe5 polymer sample containing 5 mol% of Fe, has the highest ∑R value (1.10650 cm−1) and the lowest value of the fast neutron mean free path. This means that the PPFe5 possesses better neutron shielding efficiency.
