Barium sulfate radiation-shielding mortar, also known as barium sand, heavy spar radiation-shielding mortar, or X-ray shielding mortar, is a specialized construction material specifically designed for building radiation-shielding walls, floors, and ceilings.
Its core principle lies in the high density of barium sulfate (with a specific gravity ranging from 4.2 to 4.5 g/cm³) and the heavy atoms—particularly barium—abundant in its crystal structure, which effectively block and attenuate ionizing radiation (such as X-rays and gamma rays). Compared to conventional concrete, barium sulfate mortar offers superior shielding performance at the same shielding thickness; alternatively, to meet the same shielding requirements, it can significantly reduce wall thickness, thereby saving valuable building space.
Main features:
1. High density and excellent shielding performance: Containing a large amount of barium sulfate, this material has a density significantly higher than that of ordinary mortar, enabling it to effectively absorb and scatter radiation energy.
2. Convenient construction: It has excellent workability and can be applied using standard plastering techniques, with strong adhesion to the underlying concrete walls.
3. Void-free and highly dense: A professionally formulated mix ensures that the mortar achieves a dense structure after setting, with no shrinkage cracks, thereby preventing radiation leakage.
4. Environmentally friendly and durable: Made primarily from natural barite ore, it is non-toxic, odorless, boasts stable performance, and has a long service life.
Application scenarios
Technical Parameters
Project Technical Parameters Notes/Test Standards Dry density ≥ 2.8 - 3.5 g/cm³ The core indicator is significantly higher than that of ordinary mortar (~1.8 g/cm³). Compressive strength ≥ 20 MPa Ensure the structural strength of the wall. Flexural strength ≥ 5 MPa Bond strength ≥ 0.5 MPa Ensure firm adhesion to the base layer, with no hollowing or flaking. Lead equivalent ≥ 2.0 mmPb / 10mm thickness Key protective index. It indicates the protective capability of a 10-mm-thick mortar in terms of the equivalent thickness of pure lead in millimeters. The specific value depends on the radiation energy (in kV or MeV). Shrinkage rate ≤ 0.3% Low shrinkage ensures no cracking and prevents radiation leakage. Moisture content ≤ 1.0% Construction thickness Recommended single-layer plastering thickness ≤ 20mm Layered construction is required; applying too thick a layer of plaster at one time can easily cause sagging and cracking. Mixing ratio Water: Dry powder ≈ 0.15~0.18 : 1 Add water strictly according to the mixing ratio provided by the manufacturer. Setting time Initial setting ≥ 60 minutes, final setting ≤ 12 hours There is sufficient operating time. Scope of Use
Barium sulfate radiation-shielding mortar is primarily used in various building structures and engineering projects that require shielding against ionizing radiation.
Main application areas:
1. Medical Radiology Department:
● Radiology Department: X-ray Room, DR Room, CT Scan Room, Mammography Room, DSA Catheterization Room.
● Radiation Oncology Department: Linear Accelerator Treatment Room, Co60 Therapy Room, Brachytherapy Room, Gamma Knife Therapy Room.
● Nuclear Medicine Department: PET-CT Room, SPECT Room, and Iodine-131 Ward (for shielding against gamma rays).
2. Industrial Inspection and Scientific Research Fields:
● Industrial Non-Destructive Testing Room (X-ray and Gamma-Ray Non-Destructive Testing).
● Partial shielding structures for nuclear power plants and research reactors.
● Radioactive laboratories at universities and research institutions.
3. Other special fields:
● Shielding walls around baggage security systems at airports and customs.
● Radioactive waste repository.
Construction structural part:
● Wall: Used as a substitute for part or all of concrete shielding walls, or as a protective plaster layer on the surface of concrete walls.
● Floor: The protective layer on the floor of the radiology equipment room.
● Ceiling: The ceiling shielding layer above and below, where there are radiation sources or areas requiring protection.
● Gap filling: Used to fill gaps around shielding doors, observation windows, pipe penetrations through walls, and other similar openings, ensuring the continuity of the protective barrier.
