Borated Polyethylene for Neutron Shielding

 

MarShield™ borated polyethylene is used for medical, nuclear and industrial neutron shielding. It is light-weight, cost-effective and durable and can be used for a wide variety of shielding needs. With 5% boron by weight, our borated polyethylene is effective in many applications. Grade II (yellow, 1% boron) and Grade III (red, 2% boron) are also available. Common usage includes medical vaults and doors for linear particle accelerators and other radiation applications, research applications, nuclear reactors and construction of nuclear-powered vessels.

Borotron ® Borated PE
Borotron ® Borated PE has been used as a medical and industrial shielding material to attenuate and absorb neutron radiation. This easily fabricated polymer material also offers designers greater durability and function over a wider range of temperature than traditional materials.

Borotron ® HD050
Is based on MarShield’s high performance HDPE with 5% elemental boron.

What is Borotron ® High Density PE for Neutron Shielding

• HDPE material has a high hydrogen density which slows neutron particles down so they can be absorbed.
• Boron has been added to the material to absorb the slowed neutron particles and significantly reduce byproduct gamma radiation that occurs during absorption.

Common Applications

• Medical vaults and doors for linear particle accelerators and other radiation applications.
• Hot cells.
• Nuclear Storage and transport containers.
• Nuclear detection systems.
• Nuclear reactors and nuclear power plants.
• Construction of nuclear-powered submarine vessels.
• Research and test reactors.
• Large neutron beam line applications.
• High intensity X-rays.
• Shielding for cancer treatment facilities

Note: Materials with hydrogen density are also used as a component in neutron shielding systems. If you’re looking for the broadest range of sizes and shapes in unified hydrogen rich material,
