“…For example, the XCOM software (National Institute of Standards and Technology) [10] and Monte Carlo N-Particle Transport (MCNP) are widely used for theoretical calculations of attenuation coefficients [11,12]. Additionally, user-friendly online software like Phy-X/ Photon Shielding and Dosimetry (PSD) (https://phy-x.net/ module/physics/shielding) [13] and offline software like MRCsC [14,15] and EpiXS [16,17] have been introduced for calculating photon shielding and dosimetry, as well as predicting LACs against fast neutrons from specific sources. These advancements have greatly facilitated the determination of shielding properties without relying solely on experimental procedures.…”

Background: Radiation protection is crucial in various fields due to the harmful effects of radiation. Shielding is used to reduce radiation exposure, but gamma radiation poses challenges due to its high energy and penetration capabilities.Materials and Methods: This work investigates the radiation shielding properties of polyvinylidene fluoride (PVDF) samples containing different weight fraction of tungsten carbide (WC), tungsten trioxide (WO3), and tungsten disulfide (WS2). Parameters such as the mass attenuation coefficient (MAC), half-value layer (HVL), mean free path (MFP), effective atomic number (Zeff), and macroscopic effective removal cross-section for fast neutrons (ΣR) were calculated using the Phy-X/PSD software. EpiXS simulations were conducted for MAC validation.Results and Discussion: Increasing the weight fraction of the additives resulted in higher MAC values, indicating improved radiation shielding. PVDF–xWC showed the highest percentage increase in MAC values. MFP results indicated that PVDF–0.20WC has the lowest values, suggesting superior shielding properties compared to PVDF–0.20WO3 and PVDF–0.20WS2. PVDF–0.20WC also exhibited the highest Zeff values, while PVDF–0.20WS2 showed a slightly higher increase in Zeff at energies of 0.662 and 1.333 MeV. PVDF–0.20WC has demonstrated the highest ΣR value, indicating effective shielding against fast neutrons, while PVDF–0.20WS2 had the lowest ΣR value. The Monte Carlo N-Particle Transport version 5 (MCNP5) simulations showed that PVDF–xWC attenuates gamma radiation more than pure PVDF, significantly decreasing the dose equivalent rate.Conclusion: Overall, this research provides insights into the radiation shielding properties of PVDF mixtures, with PVDF–xWC showing the most promising results.
