“…Following this, a thorough comparison was made between the obtained parameters and the corresponding values derived from lead. Although many elements and compounds have been used as radiation shields [37][38][39][40][41], between them lead is widely recognized and employed as a radiation shielding material. The density of lead, tungsten, and PVDF are 11.34, 19.25, and 1.78 gr cm −2 respectively.…”

This study examines the shielding properties of polyvinylidene difluoride reinforced with 20%, 40%, and 60% weight fractions of tungsten and compares the findings to those obtained from lead. The mass and linear attenuation coefficient, half-value layer, and effective atomic number were calculated using the Phy-X/PSD software. From the photon interactions with matter point of view, the Photoelectric effect dominates in low-energy photons, while pair production is dominant in high-energy photons; meanwhile, Compton scattering remains almost constant across the energy range. The results show that the mass attenuation coefficient is higher for low-energy photons, and composites with a higher weight fraction of tungsten exhibit higher values of mass attenuation coefficients. The half-value layer decreased as the weight fraction of tungsten increased, and the effective atomic number was higher for lower energy photons. These findings were contrasted against calculations derived for lead. Within the energy interval of 20-200 keV, the mass attenuation coefficient for lead was observed to be approximately two times that of the optimal values recorded for the specific composites under examination, whereas at 2 MeV, this discrepancy diminished. The minimum half-value layer for polyvinylidene difluoride augmented with 60% weight proportions of tungsten in comparison to lead was identified at an energy of 2 MeV. During this interval, the half-value layer for this composite material was threefold greater than that of lead. Although the mass attenuation coefficient is higher for lead, in some energy ranges (about two MeV), the findings from the selected composites are completely comparable to those from lead, demonstrating the ability and performance of the polyvinylidene difluoride composites for radiation shielding.

“…Furthermore, Pb shields exhibit limited absorption capability within the 40 to 88 keV energy range, referred to as the lead feeble absorption region [11] . A plethora of research including those on various ceramics [12] , [13] , [14] , [15] , polymer composites [16] , [17] , [18] , glass systems [19] , [20] , [21] , and metal alloys [22] , [23] , [24] , [25] , [26] has been conducted in a search of efficient materials that could replace conventional shielding facilities offered by Pb-based materials and different types of concretes. In our previous work [27] , we investigated and compared the radiation shielding properties of lightweight Ti-based bulk metallic glasses with traditional Pb and heavy concrete materials.…”

“…[1][2][3][4][5][6][7][8][9][10] Different previous works reported the attenuation coefficients for different materials such as alloys, ceramics, rocks, concrete, glasses, and glass ceramics. [11][12][13][14][15][16] Glass is one of the safest materials used for packaging due to its make-up and qualities, and it has a recycling rate of one hundred percent. By introducing additional compounds or subjecting the material to heat treatment, these characteristics can be changed and altered.…”

Several radiation shielding parameters for (75-x)B2O3-10TeO2-13SrCO3 -2ZnO-xPbO glasses were evaluated between 0.284 and 1.333 MeV. The PbO content in the glass has a positive relationship with the density of the glasses, leading to BTSZP0, the glass with no PbO, having the smallest density, while BTSZP5, which has 40 PbO mol%, has the greatest density. Radiation shielding parameters such as mass attenuation coefficients and other related factors were computed, and relationships between PbO content, energy, and density are graphed. Linear attenuation coefficient (LAC) is reported and we evaluated the impact of density on the LAC values. By adding more PbO atoms, the density of the samples increased, leading to a higher LAC. The BTSZP0 sample has the highest HVL at all tested energies, with the BTSZP5 sample having the lowest HVL. Mean free path (MFP) has an inverse relationship with the density of each sample but increases with greater incoming photon energy. The effective atomic number (Zeff) values peak at low photon energies and rise significantly with increasing PbO content. The MFP and TVL of the BTSZP glasses are compared against previously tested glass samples at a set energy, and the values demosntrated the effectiveness of the BTSZP glasses.
