MarShield Non-Lead Radiation Shielding Materials

Tungsten, Bismuth and Iron, non-lead radiation shielding offer a flexible, environmentally friendly shielding alternative. These can be flexibly affixed or moulded into any shape, allowing the application of localized shielding directly at the source.

Isolated hot spots can be shielded, eliminating the need to shield larger areas surrounding the hot spot. Lead alternative shielding can be engineered to meet weight, size, and radiation attenuation specifications. These types of products have saved power plants time and money during maintenance shutdowns. Our lead alternative shielding products are non-toxic and free of hazardous materials. These shielding materials allow us the ability to create lightweight, easy-to-use, customizable products. The weights and sizes available make them easy to handle, with improved ergonomics, reducing the prospect of lifting and handling injuries.

Lead-Free Shielding Products

Non-lead shielding products include lead-free blankets, pipe wrap, pipe shields, magnetic shields, safety floor shields, and custom-designed shielding solutions.

  • Tungsten, bismuth & iron blankets
  • Pipe wrap shielding
  • Molded pipe and elbow shielding
  • Floor shielding

Tungsten, Bismuth, Or Iron Shielding

Our lead alternative shielding technology is a flexible, innovative solution made from Tungsten Silicone,  Bismuth Silicone, or Iron Silicone. Lead-free shielding is non-hazardous and can reduce disposal costs, making it a safe and cost-effective radiation shielding alternative to lead shielding. All of our materials are compliant with nuclear industry smoke development, flame spread, and critical radiant flux measurement standards, and have demonstrated the ability to meet acceptable analysis specified within Regulatory Guide 1.36. Tungsten, Bismuth, and Iron products are rated for continuous use up to 350° F/176° C.

Non-Lead Nuclear Shielding Blankets

Non-lead nuclear shielding blankets are used as physical barriers to protect against radiation. They come in standard sizes, such as 1’ x 2’, 1’ x 3’, 1’ x 4’, 1’ x 5’, 1’ x 6’ and 2’ x 3’, and offer a range of shielding options from 5 to 20 lbs. per square foot. Custom sizes are also available to suit specific requirements. The grommets placed directly into the material are rated at 270 lbs. of pull force per grommet. Additionally, there is an optional PVC laminate covering that can be added to enhance the durability and longevity of the shielding blanket.

Non-Lead Nuclear Pipe Shields

Non-lead nuclear pipe shields are designed to protect pipes from radiation while complying with standard weight constraints. These shields are sized and shaped to easily slip on and snap tightly around pipes, providing maximum coverage. They are available in both standard and custom sizes and lengths to meet specific requirements. These shields are designed with optimal thickness at Co-60 and to prevent streaming, ensuring effective radiation shielding. Non-lead nuclear pipe shields are a reliable solution for protecting pipes in environments where radiation is present.
