Corning® Med-Gamma® Glass
Corning® Med-Gamma® Glass is a high-quality, neutral appearance glass for protective shielding from Positron Emission Tomography (PET) gamma-based radiation at various keV levels.
Key benefits:
- Protective shielding glass against gamma-based PET radiation as specified by IEC 61331:2014 (Standard Gamma Radiation).
- Extensive physical testing carried out on Corning® Med-Gamma® Glass allowing designers to specify glass with maximum confidence.
- Supplied as polished plates up to 2800 x1400 mm, with smaller sizes cut to customer requirements.
- Wide lead equivalent, thickness and size range.
- High quality and neutral appearance providing excellent visual clarity.
- Stocked worldwide through local Corning sales offices and a network of specialist partners for fast deliveries.
Product features:
Corning® Med-Gamma® Glass is supplied as:
- Polished plate up to 2800 x 1400 mm
- Cut plate supplied to customer specific sizes (with edges ground or polished and finished with safety chamfers)
- Laminated plate using PVB interlayer
Main applications:
