99.994% Pure Lead Shielding Bricks with Double-Herringbone Interlocking for 8 mm - 200 mm Radiation Protection

• Ultra-High Purity for High-Energy Attenuation: Verified 99.994% lead content provides maximum photon attenuation for megavoltage radiotherapy energies, meeting the stringent shielding requirements of LINAC vaults and cobalt-60 therapy units.
• Double-Herringbone Interlocking System: Enhanced dovetail profile on all four edges creates multi-directional mechanical locks, preventing brick displacement and maintaining shielding continuity even under structural vibration or thermal cycling.
• Heavy-Duty Wall Construction: Designed for permanent or semi-permanent bunker walls with thicknesses up to 200mm per brick layer. Multiple layers can be stacked for total shielding thicknesses specified by medical physics calculations.
• Precision Dimensional Tolerance: Each brick is machined to tight tolerances ensuring consistent stacking height and wall alignment. This precision is critical for bunker designs where shielding calculations assume uniform material distribution.
• Material Certification Included: Every production batch is accompanied by purity certification and density verification documentation, supporting medical physics acceptance testing and regulatory licensing applications.
• Seismic and Structural Stability: The interlocking design distributes lateral loads across the entire wall assembly, providing inherent stability superior to plain stacked bricks. Suitable for regions with seismic activity requirements.
• CE and ISO 9001 Certified Manufacturing: Produced under strict quality management with full traceability from raw material sourcing through final inspection.

These bunker-grade lead shielding bricks are specifically designed for the most demanding radiation therapy shielding applications. Primary use cases include linear accelerator (LINAC) treatment vaults for external beam radiation therapy, cobalt-60 teletherapy bunkers, high-dose-rate (HDR) brachytherapy procedure rooms, proton therapy facility shielding where supplementary neutron attenuation is required, and cyclotron vault construction in medical isotope production facilities.

The double-herringbone interlocking design provides the structural integrity necessary for walls exceeding 2 meters in height, making these bricks suitable for full bunker construction rather than just partial shielding supplements.

Additional applications include radiation oncology department expansion projects where existing concrete shielding requires lead supplementation, veterinary radiation therapy facilities, and research institutions operating high-energy physics experimental beamlines that require robust personnel protection.
