The Influence of Unit Cell Parameters, Intertetrahedral Bridging Angle and Chemical Composition on the Crystal γ-ray Attenuation of α-quartz Homeotypes

Unveiling the influence of crystal structure polymorphs on radiation shielding properties: A case study of SiO2

“…This result is consistent with many previous research works. [3][4][5] Alone these lines of evidence, Shaaban et al 4 have correlated the crystalline structures LAC values and incident photon energies of α-quartz under high-pressure conditions. These authors have found that crystalline structures with higher densities exhibit superior LAC values, whereas those with lower densities exhibit diminished LAC values.…”

“…The study entailed the computation of their MACs and LACs across a range of photon energies (0.015 < E < 15.0 MeV). 5 Their findings elucidate discernible dependencies of MAC and LAC values on incident photon energies, intertetrahedral bridging angles, tilt angles, and the APF on LAC values and the specific α-quartz homeotypes under. 5 The attenuation of ionized radiation in a material depends on several factors related to the atomic structure of the material, including the arrangement of atoms or molecules in a crystalline material forms a regular lattice structure.…”

“…It is important to note that although crystalline forms can influence the MAC, other material properties, such as elemental composition and density, also play significant roles. [1][2][3][4][5][6] Therefore, a comprehensive understanding of the material's characteristics is necessary to accurately determine its MAC. To our knowledge, these factors have not been considered thus far, except for a few research works, which will be summarized in the following.…”

“…Their findings shed light on how variations in these structural parameters can finely tune α-quartz's capacity to absorb radiation. 4 Another study by our group 5 has investigated the interplay between these crystal parameters and the γ-ray attenuation characteristics of α-quartz homeotypes. This group has tested diverse crystalline forms of α-quartz homeotypes, each distinguished by varying densities, which were selected and subjected to comprehensive analysis with respect to their radiation shielding properties.…”
