Product Overview
Barium Sulfate Radiation Shielding Mortar, also known as barium sand, barite radiation shielding mortar or X-ray shielding mortar, is a specialized building material used for constructing radiation shielding walls, floors and ceilings.
Its core principle utilizes the high density of barium sulfate (specific gravity up to 4.2-4.5 g/cmΒ³) and the heavy atoms (barium) rich in its crystal structure, which effectively absorb and attenuate ionizing radiation such as X-rays and gamma rays. Compared to traditional concrete, barium sulfate mortar provides superior shielding performance at the same thickness, or significantly reduces wall thickness while achieving the same protection level, saving valuable building space.

Advantages
High-Density Shielding Performance
High barium sulfate content with specific lead equivalent β₯0.12mmPb/mm, achieving β₯2.0mmPb shielding at 10mm thickness.
Low Shrinkage & Crack Resistance
Low-shrinkage formulation with no early-age drying cracks, eliminating radiation leakage risks.
Easy & Controllable Construction
Traditional plastering application with ample working time; thick protective walls require layered construction.
Applications & Operation Video
Trusted across diverse construction scenarios
Medical Facilities
X-ray rooms, CT scan rooms, radiotherapy departments, dental clinics and operating theaters.
Industrial Facilities
Industrial X-ray inspection rooms, non-destructive testing laboratories and radiation work areas.
Research Institutions
Nuclear research laboratories, particle accelerator facilities and radioactive material handling areas.
