Area of Science:

• Materials Science
• Nuclear Engineering
• Polymer Science

Background:

• Gamma radiation shielding is critical for safety in nuclear power, medical imaging, and space exploration.
• Developing flexible materials with high radiation attenuation capabilities is essential for effective shielding.
• Polyvinyl alcohol (PVA) is a polymer with potential for radiation shielding applications.

Purpose of the Study:

• To enhance the gamma radiation shielding properties of polyvinyl alcohol (PVA) by incorporating glass.
• To investigate the effectiveness of PVA-glass composites in attenuating gamma rays.
• To evaluate the potential of these composites as cost-effective and sustainable shielding materials.

Main Methods:

• Fabrication of PVA-glass composite materials with varying glass percentages.
• Experimental determination of gamma-ray interaction parameters, specifically the mass attenuation coefficient (μ/ρ).
• Measurement of shielding effectiveness using gamma sources like 137Cs (661.6 keV) and 60Co (1173 and 1332 keV).

Main Results:

• The PVA-glass composite demonstrated superior gamma radiation shielding properties compared to pure PVA.
• The mass attenuation coefficient (μ/ρ) was successfully determined for the composite across different gamma-ray energies.
• Incorporating glass significantly improved the radiation attenuation capabilities of the PVA matrix.

Conclusions:

• PVA-glass composites offer enhanced gamma radiation shielding performance.
• These composites represent a promising, cost-effective, and sustainable solution for radiation shielding.
• The findings support the use of PVA-glass materials in diverse radiation environments.
