Barium sulfate radiation shielding mortar, also known as barium sand, barite radiation shielding mortar, or radiation protection mortar, is a special construction material specifically used for building radiation shielding walls, floors, and ceilings.
Its core principle is to utilize the high density of barium sulfate (specific gravity up to 4.2-4.5 g/cm³) and the heavy atoms (barium) abundant in its crystal structure to effectively block and attenuate ionizing radiation (such as X-rays and gamma rays). Compared with traditional concrete, barium sulfate mortar provides superior protection performance at the same protective thickness, or can significantly reduce wall thickness to save building space while meeting the same protection requirements.
Main Features:
1. High Density and Excellent Protection: Contains a large amount of barium sulfate, with density much higher than ordinary mortar, effectively absorbing and scattering radiation energy.
2. Easy Construction: Good workability, can be applied using ordinary plastering techniques, and bonds firmly with the base concrete wall.
3. Void-Free and Highly Dense: Professional formulation ensures the mortar structure is dense after setting, with no shrinkage cracks, preventing radiation leakage.
4. Environmentally Friendly and Durable: Mainly composed of natural barite mineral, non-toxic and odorless, stable performance, and long service life.
Technical Parameters
Item Technical Parameter Remarks/Test Standard Dry Density ≥ 2.8 - 3.5 g/cm³ Core indicator, much higher than ordinary mortar (~1.8 g/cm³) Compressive Strength ≥ 20 MPa Ensures wall structural strength Flexural Strength ≥ 5 MPa Bond Strength ≥ 0.5 MPa Ensures firm bonding with the base layer, no hollowing or detachment Lead Equivalent ≥ 2.0 mmPb / 10mm thickness Key protection indicator. Indicates how many millimeters of pure lead the protection ability of 10mm thick mortar is equivalent to. The specific value depends on radiation energy (KV or MeV). Shrinkage Rate ≤ 0.3% Low shrinkage ensures no cracking, preventing radiation leakage Moisture Content ≤ 1.0% Application Thickness Single plastering recommended ≤ 20mm Layered construction required; too thick plastering at once may sag or crack Mixing Ratio Water: Dry powder ≈ 0.15~0.18 : 1 Strictly add water according to the manufacturer's provided ratio Setting Time Initial set ≥ 60 minutes, final set ≤ 12 hours Sufficient working time Scope of Use
Barium sulfate radiation shielding mortar is mainly used in various building structures and projects requiring ionizing radiation shielding.
Main Application Areas:
1. Medical Radiology Departments:
● Radiology: X-ray rooms, DR rooms, CT scan rooms, mammography rooms, DSA catheterization rooms.
● Radiotherapy: Linear accelerator treatment rooms, Co60 treatment rooms, brachytherapy rooms, Gamma Knife treatment rooms.
● Nuclear Medicine: PET-CT rooms, SPECT rooms, Iodine-131 wards (for gamma ray protection).
2. Industrial Inspection and Research Fields:
● Industrial flaw detection rooms (X-ray, gamma ray nondestructive testing).
● Partial shielding structures in nuclear power plants and research reactors.
● Radioactive laboratories in universities and research institutions.
3. Other Special Fields:
● Shielding walls around baggage inspection systems at airports and customs.
● Radioactive waste storage facilities.
Construction Structural Parts:
● Walls: Replace part or all of concrete shielding walls, or serve as protective plaster layers on concrete walls.
● Floors: Protective layers on floors of radiation equipment rooms.
● Ceilings: Shielding layers on ceilings where radiation sources are located above or below, or in areas requiring protection.
● Gap filling: Used for filling gaps around security doors, observation windows, pipeline wall penetrations, etc., to ensure continuity of protection.
