Radiation Shielding Glass
High-efficiency shielding: high lead content (density 6.2-8.0 g/cm³) strongly absorbs X/γ rays, lead equivalent 0.5-8.0mmPb can be customized freely;
Transparent monitoring: light transmittance>80%, no visual distortion, and real-time observation of the radiation area;
Sturdy and durable: impact resistance, corrosion resistance, anti-aging, life span of more than 15 years;
Safety and environmental protection: lead elements are stably sealed without precipitation risk.
Irreplaceability: the only radiation shielding material that combines strong protection and high light transmittance, a rigid demand in the medical, nuclear industry, and security inspection fields.
Radiation shielding glass product technical specifications
Material structure
Using high-purity quartz sand as the matrix, 20%-80% lead oxide (PbO) is melted and doped to form a homogeneous glass body with a density of 6.2-8.0 g/cm³. The lead element is locked in the silicon-oxygen network in an ionic state to ensure no leakage risk (in compliance with ROHS/ISO 14001 standards).
