Summary
This study synthesized potassium-barium borate glasses with varying cadmium oxide (CdO) content. Higher CdO concentrations improved gamma-ray shielding, identifying an optimal composition for effective radiation protection.
Area of Science:
- Materials Science
- Nuclear Engineering
- Condensed Matter Physics
Background:
- Borate glasses are investigated for radiation shielding applications.
- The influence of heavy metal oxides, like cadmium oxide (CdO), on glass properties is crucial for enhancing shielding performance.
Purpose of the Study:
- To synthesize and characterize potassium-barium borate glasses with varying CdO concentrations.
- To evaluate the gamma-ray shielding efficiency of these glasses using advanced simulation techniques.
Main Methods:
- Melt-quenching technique for glass synthesis.
- X-ray diffraction (XRD) for structural analysis (amorphous nature).
- Monte Carlo simulations (MCNPX) to determine mass attenuation coefficients (μm) and other shielding parameters (HVL, MFP, Neff, Zeff).
- Validation of simulation results using Phy-X/PSD software.
Main Results:
- All synthesized glasses were fully amorphous.
- Increasing CdO content enhanced glass density and network compactness.
- Gamma-ray shielding efficiency increased with higher CdO concentrations.
- An optimal CdO concentration of ~13 wt% was identified for sample S4.
- Simulation results showed good agreement with validated data (RD < 1.025%).
Conclusions:
- Potassium-barium borate glasses with CdO exhibit promising gamma-ray shielding properties.
- The developed glass system shows potential as efficient radioprotective materials.
- The study provides valuable data for designing advanced radiation shielding materials.
