Radiation shielding glass

The most critical factor is the Lead Equivalent (Pb thickness), which must match the energy level of the radiation source (e.g., X-ray, CT, or PET scan). For standard X-ray rooms, 2.0mm Pb is common, while CT rooms often require 3.0mm Pb or higher. Always verify that the supplier provides a shielding thickness calculation report aligned with your specific medical or industrial equipment specifications.

Ensure the glass complies with IEC 61331-2:2014 (Protective devices against diagnostic medical X-radiation). For the US market, FDA registration is essential, while the European market requires CE marking. You should also request ISO 13485 certification from the manufacturer to ensure the product meets medical device quality management systems.

High-quality radiation glass should have a light transmission rate of over 85% to ensure clear visibility for technicians. Check for internal bubbles, inclusions, or scratches, as these can impair vision and indicate poor manufacturing. Since lead glass is softer than normal glass, prioritize suppliers offering laminated lead glass or those who provide specialized anti-scratch coatings for high-traffic environments.

Primary applications include Medical Diagnostic Rooms (X-ray, CT, PET/CT), Nuclear Power Plants, Industrial Non-Destructive Testing (NDT) labs, and Scientific Research Facilities. Each scenario has different radiation energy levels, so the glass must be customized for gamma-ray or X-ray attenuation accordingly.

Radiation glass is extremely heavy and brittle. You must mandate customized fumigated wooden crate packaging with internal shock-absorbing foam and vacuum-sealed moisture barriers to prevent oxidation (yellowing). Ensure the shipping terms include 'Fragile' labeling and use a freight forwarder experienced in handling Class 7 related materials or heavy medical components.

When sourcing on Made-in-China.com, focus on factory audits and third-party testing. Negotiate for a sample piece (e.g., 100x100mm) to be sent for local lab verification before placing a bulk order. Request a tiered pricing structure where the unit price decreases by 10-15% for orders exceeding 20 square meters, and insist on a 12-24 month warranty against discoloration.

Utilize Secured Trading Services provided by Made-in-China.com to protect your funds until the goods are delivered and inspected. For large-scale projects, use a Letter of Credit (L/C) or a 30% deposit / 70% balance after third-party inspection (SGS/TUV) at the loading port to mitigate financial risk.

Check the HS Code (typically 7011 or 7013 series) for your specific country to determine import duties. Be aware that some regions classify lead glass as a regulated medical accessory, requiring specific import licenses or radiation safety permits. Always confirm with your local customs broker if a Certificate of Origin is needed to benefit from preferential tariff rates.
