Ionizing radiation is vital in various fields but poses health risks, necessitating effective shielding. This study investigated the photon-shielding properties of polyester-based ternary composites with barite (BaSO4) and tungsten (W) using experimental methods, theoretical calculations, and Monte Carlo simulations for energies between 81 keV and 1332.5 keV. WINXCOM was utilized for the theoretical predictions, and the MCNP6 and PHITS 3.22 algorithms were employed for the simulations. According to the results, the simulation, theoretical, and experimental data all closely aligned. At 81 keV, the composite containing the highest amount of tungsten (PBaW50) had the highest mass attenuation coefficient (3.7498 cm2/g) and linear attenuation coefficient (12.9676 cm−1). Furthermore, for a sample that was 1 cm thick, PBaW50 offered 99.88% protection at 81 keV and had the lowest HVL and TVL values. PBaW50 exhibited attenuation capabilities, making it appropriate for use in industrial, medical, and aerospace settings. In summary, the findings of this study underscore the potential of polyester-based composites doped with barite and tungsten as effective materials for gamma radiation shielding. The PBaW50 sample, in particular, stands out for its attenuation performance, making it a viable option for a wide range of applications where durable and efficient radiation shielding is essential.

“…Recently, significant attention has been directed towards advancements in producing various composite shielding materials. These include amorphous glasses or ceramics [27][28][29][30]; polymer matrices embedded with rare-earth metal particles or oxide inclusions (such as iron oxide and bismuth) [31,32]; and composite multilayer films, which are primarily used for electromagnetic radiation shielding [33,34]. At the same time, the assessment of the shielding efficiency of these films is determined both during full-scale experiments using various reference sources of ionizing radiation (Co 57 , Co 60 , Na 22 and Cs 137 ) [35,36] and by simulation of the processes of ionizing radiation interaction with matter using program code based on the Monte Carlo method [37,38].…”

In this research, the formation processes of CuBi2O4 films were examined using atomic force microscopy, energy dispersive analysis and X-ray diffraction analysis methods. The films were synthesized through electrochemical deposition from sulfuric acid solutions at a potential difference of 3.5 V. The duration of film growth was set to between 10 and 90 min to assess the possibility of controlled film growth and preserve the stability of their structural properties during growth over an extended period. An analysis of the data obtained by X-ray diffraction revealed that the resulting film samples are highly ordered structures with a tetragonal CuBi2O4 phase. The results of the connection between the thickness of CuBi2O4 films and strength properties depending on the time of film deposition were obtained. The results of the shielding efficiency of low-energy γ-quanta using CuBi2O4 films were obtained.

Shotcrete is a construction material that is applied by spraying under high pressure, and there are many factors that affect its properties. In this study, the effect of cement dosage and water-to-cement ratio on the compressive strength and drying shrinkage performance of shotcrete was investigated. For this purpose, shotcrete specimens were produced using three different water-to-cement ratios (0.40, 0.45, 0.50) and three different cement dosages (400, 450, 500). The unit weight, ultrasonic pulse velocity (UPV), compressive strength, splitting tensile strength, and drying shrinkage performance of the produced specimens were examined. As a result of the experimental studies, an increase in cement dosage resulted in an increase in unit weight values, with the amount of increase ranging from approximately 1% to 3%. When the UPV value was examined, an increase in cement dosage resulted in an increase in UPV values, with an increase of approximately 1% to 5%. An increase in cement dosage also resulted in an increase in compressive strength and splitting tensile strength values, with the increase ranging from approximately 12%-16%, 5%-9%, and 10%-12% for the 500, 450, and 400 dosage groups, respectively. The drying shrinkage values increased with increasing cement dosage, the highest shrinkage values occurred in the groups with 0.50 water/cement ratio and 500 dosage, and it was observed that 85-95% of the total shrinkage of the shotcrete specimens was completed within the first 1 hour. Furthermore, the data obtained can be used to determine the optimum water/cement ratio and cement dosage for the construction of shotcrete.
