Shielding
Broad experience has made RPS the leader in ionizing radiation shielding services. Once dedicated to the nuclear division of the U.S. Navy, we began over 35 years of service to commercial utilities as an emergency response team called to Three Mile Island.
Our engineering staff has more than 100 man years of experience in custom design of shielding through the application of lead, steel, water, borated plastics and other materials.
The provided links below outline some of our recent projects and show why, after more than 35 years, RPS remains the leader in shielding applications.

ShieldingCounting Cave (Shielding)
The epoxy coated, seal welded shielded cave surrounds the frisker probe to shield background radiation for on-site use. The cave has an opening 4” wide x 6 ½” high x 11” deep and 2” steel shielding on five sides. It has an angular hole in the back face of cave for the probe wire and threaded holes with removable lifting eyes for cave handling. Available with a shielded door.
The shielded cave may also be mounted on a heavy duty epoxy coated, welded structural steel mobile cart on four casters (two rigid, two swivel locking) that is easily relocated to the work site. The top of the cart supports the cave with space for the monitor and information recording. It also has two lower shelves for storage.
The probe holders are stainless steel and maintain uniform distance from probe to sample.
Currently available for:
- Ludlum Model 43-93
- Ludlum Model 43-5
- Ludlum Model 44-9
- Holders for other models available upon request

ShieldingMobile Shield Walls
Mobile Shield Walls are constructed of 1″ – 4″ thick lead encased in stainless steel. There are nine interlocking panels: seven panels that are 11′ 6″ tall and two panels that are 8′ 6″ tall. Each panel is equipped with a handle for moving into position and rolls on two inline wheels. The floor track is a key locking design with three direction changes and there are two top end tracks to steady the panels. The tracks are adjustable to align with the floor.

Frisking BoothsLWB Booth
The Lead Wool Blanket Frisking Booth offers the conveniences of portability and adaptability. Shielding attenuation can be regulated by the installation of standard 1′ x 4′ Lead Wool Blankets in the areas of interest. The booth frame can be easily handled when no lead wool blankets are installed. The booth sections are of welded construction. The sections are bolted together to form the booth. The structural steel frame is epoxy coated or powder coated. Blanket support rods, spaced every 4”, are located at two levels to support the blankets. The blanket walls can be 1 to 4 layers thick. Blankets can be laid on the top frame section to create a shielded ceiling. The standard booth measures 36″ wide x 48″ deep x 96″ high and can be disassembled for storage.
