High-Density Concrete & Radiological Shielding
Integrated Engineering Solutions for Ionizing Radiation Protection
For decades, High-Density Concrete has been one of the most effective construction materials used for Ionizing Radiation Shielding. Its combination of structural performance and radiation attenuation makes it an essential component of facilities requiring long-term radiological protection.
With more than 20 years of experience, SURICO has participated in the delivery of projects where radiological protection forms an integral part of the building design.
Our engineering capabilities include the design and construction of Radiological Shielding systems, High-Density Concrete technology, protective shielding plasters, lead-lined shielding systems and the supply of specialist High-Density Aggregates for radiation-protection applications.
Every solution is engineered according to the operational requirements of the facility, applicable radiation-protection standards and the specific characteristics of the radiation source.
High-Density Concrete
High-Density Concrete is one of the principal construction materials used for Ionizing Radiation Shielding.
By incorporating carefully selected High-Density Aggregates, it provides effective attenuation of X-ray and gamma radiation while maintaining the structural performance expected of modern reinforced-concrete construction.
High-Density Concrete is widely used in:
- Radiotherapy facilities
- Diagnostic imaging departments
- CT and MRI support facilities
- Mammography suites
- Nuclear medicine departments
- Research laboratories
- Industrial radiation facilities
- Other buildings requiring permanent Radiological Shielding
Depending on the engineering requirements, different aggregate systems are selected to achieve the specified concrete density, structural properties and shielding performance.
Barite Concrete
Barite Concrete remains one of the most widely recognised terms within the radiation-shielding industry.
Although modern High-Density Concrete technology now incorporates a variety of specialist aggregates, the term Barite Concrete continues to be commonly used by architects, engineers, contractors and facility owners when referring to concrete designed for Radiological Shielding.
Today, Barite Concrete represents one of several engineering solutions available for achieving project-specific radiation protection requirements.
Shielding Plasters
Protective shielding plasters have been used for many years to provide local protection against diagnostic X-ray radiation.
Modern shielding plaster systems are engineered using different combinations of shielding materials selected according to the radiation characteristics and performance requirements of each individual project.
Often referred to as Barite Plaster, these systems are particularly suitable for:
- refurbishment projects,
- diagnostic imaging departments,
- CT facilities,
- mammography suites,
- medical examination rooms,
- and other environments where effective Radiological Shielding must be achieved while maintaining limited wall thickness.
Lead-Lined Radiological Shielding Systems
For many projects, lead-lined shielding systems remain the most practical engineering solution.
Lead sheets and lead foils enable high levels of radiation attenuation while maintaining relatively thin wall constructions, making them particularly suitable for both new construction and refurbishment projects.
SURICO designs and installs complete lead-lined shielding systems incorporating:
- Lead sheets,
- Lead foils,
- Protective shielding plasters,
- and project-specific construction details
to achieve the required level of radiation protection.
Typical applications include:
- Radiology departments
- CT facilities
- Mammography suites
- Angiography rooms
- Diagnostic imaging centres
- Other medical facilities using X-ray equipment
High-Density Aggregates
For more than two decades, SURICO has supplied High-Density Aggregates for the production of High-Density Concrete used in Radiological Shielding, specialised structural applications and engineering projects requiring increased material density.
We also provide technical support for:
- concrete mix design,
- aggregate selection,
- density optimisation,
- and engineering guidance for project-specific concrete technologies.
Many projects continue to use terms such as Barite Concrete, Barite Aggregate or simply Barite.
These expressions remain firmly established within industry terminology.
In practice, however, modern High-Density Concrete technology employs a range of specialised High-Density Aggregates selected according to the required concrete density, shielding performance and structural engineering objectives.
Barite Aggregate continues to be one of the most widely used materials for High-Density Concrete intended for Radiological Shielding, although the final aggregate selection always depends on the engineering requirements of the project.
