Abstract
The attenuation of γ-rays in α-quartz homeotypes is influenced by various factors, including unit cell parameters, intertetrahedral bridging angle, and chemical composition. This study aims to investigate the correlation between these crystal parameters and the attenuation properties of γ-rays in α-quartz homeotypes. Thirteen different crystalline forms of α-quartz homeotypes with varying densities were chosen and analyzed for their shielding properties. Their mass attenuation coefficients (MAC) and linear attenuation coefficients (LAC) were calculated for a range of photons energies using XCOM online software. The results revealed distinct dependencies of MAC and LAC values on incident photon energies and α-quartz homeotypes. They follows the following sequential order in the low and high energy domains:MACGaAsO4 < MACGaO4 > MACBAsO4 > MACAlAsO4 > MACGaPO4 > MACAl0.33Ga0.67PO4 > MACFePO4 > MACPON > MACSi0.56P0.44O1.56N0.44 > MACAlPO4 > MACSiO2 > MACBPO4 > MACBeF2. The GaAsO4 homeotype exhibited the highest MAC values at low incoming photon energies, while the BeF2 compound displayed the least MAC values. The LAC values also demonstrated variations among the homeotypes, with GeO2 (with a = 4.9845 Å, c = 5.6477 Å, ρ = 4.2700 g/cm3, APF = 0.408) exhibiting the highest values. The influence of the intertetrahedral bridging angle and tilt angle on LAC values was investigated, indicating that an increase in the intertetrahedral bridging angle (or a decrease in the tilt angle) led to a decrease in LAC. This study provides valuable insights into the structural-radiation absorption properties of α-quartz homeotypes and their potential applications in radiation shielding, paving the way for the development of novel materials with optimized radiation shielding efficiency.
