Nuclear medecine room radiation shielding block

for radiation therapy rooms

Product introduction
Barium sulfate bricks are manufactured from multiple oxides and sulfates, cement, selected rare-earth additives and reinforced with plant fibers. They are designed for fixed radiation shielding applications in medical environments and renovation projects requiring lead-equivalent protection.

Product performance

• Stable physical and chemical performance; suitable for surface finishing; fire-resistant, moisture-resistant, oxidation-resistant and impact-resistant; non-toxic and environmentally acceptable. Applicable for hospitals and other sites requiring radiation protection renovation.
• High specific gravity yields effective radiation attenuation. On-site construction and installation must follow process specifications to ensure shielding performance meets design requirements.
• Halogen-free, low-smoke, non-dripping, acid-resistant and odorless; dimensionally stable with no expansion, high decomposition temperature and no corrosive effect on adjacent facilities—suitable for halogen-free flame-retardant and radiation shielding applications.

Technical parameters

• Standard dimensions: 120 mm × 240 mm × 50 mm
