”MarShield has 40 years of experience in the manufacturing of leaded wool blankets
One of our most recognized shielding products is the lead wool blanket. Built to last, the proven strength and durability of these blankets are found within their formulation and construction. Each blanket is layered in continuous lead wool rope, minimizing gaps and increasing attenuation.
Our lead blankets are highly flexible and are manufactured in a multitude of sizes, shapes and weights for effective shielding around components. The lead blankets are used in countless applications across the nuclear industry, yet still, every day, we are challenged with and define new solutions for its customers’ unique applications.
Benefits
- Mold lead blankets to many components
- Lead wool rope stability, even with continuous hanging and rough use, has been proven to last more than 30 years
- Customize outer covers with choice of color, material and company information
- Information related to previous orders can be tracked because every lead wool blanket has a traceable lot number

Standard Lead Blankets
-
Handles
Handles set on the long sides of the blankets allow workers to lift and place blankets with ease. Blankets can now be easily and quickly moved from storage to hooks or racks in the areas they are needed. The larger borders on these blankets make for handles that can easily accommodate a gloved hand.
- Faster and easier handling
- More maneuverability
- Carry a blanket with one hand
- Better leverage for installation
-
Printing
- Weight of each blanket printed on the front
- Part and lot numbers for quick identification
- Custom printed plant/utility logos
- Print extra details such as what unit the blanket should be in or what application it is for
-
RFID Tags
Located under the label and used in conjunction with a scanner, RFID tags give a unique ID to each blanket at keeps track of its movement.
- Quick counting
- Keep track of how many blankets go in and out
- Inventory management

Custom Lead Blankets
-
Curved Blankets, Magnets, Straps
Lead wool blankets can be designed and made with nearly any 2D layout imaginable . Add magnets, Velcro, cutouts, grommets, and cinch straps, and create a blanket truly designed specifically to get the job done.
-
Nozzle Shielding
We have worked with several BWR plants to create bio-door and nozzle shielding. The circular magnetic shielding is designed to fit snuggly around the nozzle. All pieces are made to fit for each plant’s specifications.
-
Steam Gen Shielding
Custom fit to any plant’s steam generators, these magnetically secured lead wool panels provide shielding between the worker and the side of the steam generator. The magnetism of these blankets allow for quick installation on any carbon steel surface while offering a significant dose reduction.
High Temperature Lead Blankets
-
Alpha Maritex Blankets
Available in various sizes, shapes and weights, our alpha maritex coverings can withstand continuous temperatures of 550+ degrees Fahrenheit (288 degrees Celsius). The blankets are typically used in high temperature applications and have been used as permanent shielding in some facilities.
-
Lead Wool Magnetic Shielding Tiles
These magnetic tiles allow for quick installation on any carbon steel surface while offering a significant dose reduction. The tiles are easy to use and are moldable to slightly curved surfaces. Low profile hand-holds allow for easy transport to the shielding location. Used in conjunction with other tiles, minimal streaming of radiation can be achieved.
Accessories
Serprentine Racking Systems
Our serpentine system is designed to provide virtually any shielding wall configuration, including low dose waiting areas, portable frisking caves, shadow shield walls, and shields for rad materials transfers.
This sturdy and adjustable system was designed to replace scaffolding, currently used to hang Lead or Tungsten Blankets. By placing the installation process in the hands of the RP department, setup time and potentially critical path time is saved.
We also offer a variety of H-Frame and custom racks to meet any needs a plant may have.
-
Cargo Nets
Substitute scaffolding with lattice webbing and integral swivel hooks. These systems are custom manufactured to work with pipes, tanks, or other applications.
-
Hooks & Straps
We carry S-Hooks in a variety of standard sizes in both carbon steel and stainless steel. For added security, spring clips can be added to ensure the blanket cannot fall off the S-Hook. Cinch and ratchet straps also in stock to tie together and hold shielding in place.
