Neutron Shielding (Borated Polyethylene (BPE))
Astra Shield provides expertly engineered neutron shielding solutions for facilities that handle neutron-emitting sources. This includes locations such as nuclear research labs, cyclotron centers, medical isotope production units, and high-energy particle testing environments.
Neutron radiation is highly penetrating and necessitates the use of specialized hydrogen-rich materials to effectively slow down and capture these particles. Our shielding systems are custom-tailored to the specific intensity, configuration, and safety requirements of each application.
Astra Shield adheres to a range of compliance standards, including:
- IAEA Radiation Protection Guidelines
- NCRP Reports (National Council on Radiation Protection)
- Local UAE & GCC Radiation Safety Regulations
- FANAR Regulations of UAE
Shielding Materials We Use:
Borated Polyethylene- BPE:
This material is a hydrogen-rich polymer infused with boron, making it ideal for thermal neutron absorption. It is suitable for modular panel installations around neutron sources or beam lines.
High-Density Concrete
We utilize customized concrete mixes that incorporate hydrogenated and borated aggregates, making them ideal for structural shielding in bunker walls, vaults, or floors.
Layered Composite Shielding
Our multi-layer systems combine various materials, such as polyethylene, lead, and steel, to effectively attenuate both neutrons and any secondary gamma emissions.
Our Approach:
Our comprehensive approach to neutron shielding includes:
- We conduct thorough evaluations of the source strength, geometry, and radiation patterns to accurately determine the specific shielding needs.
- Custom Shielding Design: Solutions are modelled to optimize thickness, layout, and materials, taking into account the neutron energy spectrum and occupancy limits.s
