Summary
Quaternary SeTeSnCd chalcogenide glasses show excellent radiation shielding, outperforming commercial options. Increased cadmium content significantly enhances shielding performance for diagnostic imaging applications.
Area of Science:
- Materials Science
- Nuclear Engineering
- Medical Physics
Background:
- Radiation shielding is crucial for protecting individuals and equipment from harmful radiation.
- Chalcogenide glasses (ChGs) are being explored as advanced materials for radiation shielding applications.
- Optimizing the composition of ChGs is essential to enhance their attenuation properties.
Purpose of the Study:
- To investigate the gamma-ray and X-ray attenuation properties of quaternary SeTeSnCd chalcogenide glasses.
- To evaluate key radiation shielding parameters and their dependence on glass composition and photon energy.
- To compare the shielding performance of the developed ChGs with conventional shielding materials.
Main Methods:
- Experimental measurement of linear attenuation coefficient (LAC) using a high-purity diode detector and radioactive sources.
- Calculation of shielding parameters: transmission factor (TF), half-value layer (HVL), tenth-value layer (TVL), mean free path (MFP), and radiation protection efficiency (RPE).
- Theoretical validation of shielding parameters using the Phy-X/PSD program.
Main Results:
- Radiation shielding performance significantly improves with increasing cadmium content in SeTeSnCd glasses.
- High radiation protection efficiency (RPE) approaching 100% at low photon energies was observed.
- The studied ChGs demonstrated superior shielding capabilities compared to commercial glasses (RS 360, RS 253G18, Types A, B, C).
- The synthesized 2 mm ChGs exhibited better RPE than 10 mm commercial glasses.
Conclusions:
- Quaternary SeTeSnCd chalcogenide glasses are promising materials for radiation shielding in diagnostic imaging.
- The enhanced shielding properties, particularly with higher cadmium content, make them suitable for mammography, dental radiography, and CT/PET systems.
- These novel ChGs offer a potential alternative to conventional shielding materials, providing better protection at reduced thickness.

02:58Crystal Field Theory - Octahedral Complexes
Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

03:02Colors and Magnetism
Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.

02:42Valence Bond Theory
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...
01:24The Seven Crystal Systems: Overview
Crystals with various point group symmetries belong to different crystal classes, which are synonymous terms. Despite being in the same class, crystals may have distinct shapes, like cubes and octahedra. There are 32 three-dimensional point groups, all of which are systematically divided into seven crystal systems.The basic cubic crystal system, exemplified by NaCl, features orthogonal vectors (α = β = �� = 90°) of equal lengths (a = b = c). When specific requirements are not imposed on the...
02:46Crystal Field Theory - Tetrahedral and Square Planar Complexes
Tetrahedral Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
