Fabricated out of 99.99‑percent high‑purity electrolytic lead, this shielding material reaches a density of 11.34 g/cm³ with atomic number 82. Widely accepted as a reference substance, it delivers effective attenuation against high‑energy X‑ray, gamma‑ray as well as neutron radiation. One‑millimetre panel provides 1 mmPb shielding equivalence，Featuring outstanding space‑saving traits and reliable radiation blocking capacity, this material serves as an irreplaceable option for nuclear power facilities, medical radiotherapy departments and other demanding industrial scenarios.
Five Key Merits
Outstanding Radiation Attenuation Capability
This material delivers more than 99.5 % shielding performance for medical‑grade X‑rays spanning 80‑150 kV. Each extra 1 mm of material thickness cuts 30 % intensity of Co‑60 gamma rays. Tolerance for lead‑equivalent value is tightly limited to ±0.1 mm, which ensures precise and uniform radiation‑blocking outcomes.
Superb resistance to diverse environmental conditions and long‑term service life
For medical CT chamber applications, merely 2 mm thickness offers protective effects matching a one‑metre‑thick concrete barrier. It can reduce occupied construction space by up to 90%, making it perfectly suited for facility retrofit assignments.
Great Field‑Installation Compatibility
This substance allows cutting and welding operations. Lead coils are bendable to enclose pipes and machinery components. The lowest permissible bending radius should be no less than five times the panel thickness. It can closely conform to curved wall surfaces and intricate structural layouts.
Extended Service Lifespan
It withstands both acid and alkaline corrosive agents. Functional properties remain steady within ‑50 °C to 150 °C operating scope. Anti‑ageing characteristics grant it a service life beyond 50 years, and practically no ongoing maintenance expenditure will be required.
Green‑Oriented & Economical Choice
All discarded lead scraps can be recovered and remelted for reuse. When evaluating long‑run expenditure, it outperforms substitute options such as barium‑sulfate‑based shielding materials.
Primary Application Fields
Radiotherapy Treatment Bays
Linear accelerator systems utilize 10‑15 mm lead sheet outer casings. Such protective configuration lowers scattered radiation readings beneath 0.1 μSv/h and satisfies every criterion laid out in global safety codes.
Interventional Procedure Lab
Wall‑mounted integrated shielding modules of 2.0 mmPb grade are deployed here. They intercept persistent scattered rays generated during clinical operations and shield clinical staff against cumulative occupational radiation exposure.
Nuclear Sector Protection
Radioactive Waste Containment Vessel
This composite structure consists of lead sheet inner liners alongside outer carbon‑steel frames, holding surface dose rates for Cs‑137 consistently under 2 mSv/h.
Industrial and Research‑Oriented Radiation Attenuation
Synchrotron Beam Facility
Custom‑fitted lead‑enclosed ductwork absorbs high‑energy bremsstrahlung released by electron‑beam operations.
Cutting‑Edge & New‑Generation Use Cases
Radiation‑Attenuating Hospital Elevator Shaft
Embedded lead sandwich layers are structurally merged into building frameworks, preventing residual radiation from propagating inside purpose‑built hospital elevator hoistways.
