Plasti-Shield Boron-Filled Polyethylene Shielding is a lightweight, cost-effective neutron shielding solution


Plasti-Shield ® Boron Filled Polyethylene Neutron Shielding, supplied by MarShield, is a lightweight, cost-effective neutron shielding solution to attenuate and absorb neutron radiation and is an extremely effective for applications in industrial, healthcare cancer treatment centers, diagnostic and hospital facilities.

Plasti-Shield Boron-Filled Polyethylene Shielding is a lightweight, cost-effective neutron shielding solution

Most radioactive fields consist of different types of radiation. The most common include fast neutron, thermal neutron, primary gamma rays and secondary gamma rays. Plasti-Shield ® is a borated polyethylene designed to attenuate these types of radiations.

  • Fast Neutrons are most effectively shielded by hydrogen. Plasti-Shield ® has an inherently high concentration of hydrogen, over 13% of volume.
  • Thermal Neutrons are shielded by polyethylene with the presence of boron, such as Plasti-Shield ® Industrial Grade with 5% boron by weight.
  • Primary Gamma Rays are best shielded with lead or other high-density materials. It is common to combine a lead lining with Plasti-Shield ® in applications requiring attenuation of primary gamma rays.
  • Secondary Gamma Rays are created by the capture of thermal neutrons by hydrogen. These captured gamma rays can be minimized by adding boron, resulting in a significantly reduced energy dosage of only .42 MeV.
For easy installation, MarShield’s borated polyethylene comes in a standard sheet size of 48” x 96” x 1” thick. You can easily cut this polymer material using standard woodworking tools.
