Our radiation shielding materials product line is the broadest in the industry, truly allowing us to offer the best available solution to the ALARA challenges faced by nuclear professionals around the world.

Radiation Shielding Attenuation Calculator

NPO’s Radiation Shielding Attenuation Calculator is a quick and free tool for you to use to accurately determine the optimal shielding material and thickness to achieve the desired level of protection.

Our Scientists at NPO have used their knowledge and expertise to develop the attenuation calculator to provide highly accurate attenuation data for various shielding materials, including NPO’s T-Flex products.

“The product is just what we wanted.”
Corey F, Sr. Radiological Engineer
“The molded shielding was extremely fast, simple, and easy to install. My shielding team members were elated for how fast they were able to install this shielding. Thank you, NPO, this is a fantastic product.”
Romalis DALARA Planning
“The shielding NPO made us for the Pressurizer Spray Line went perfect.”
Martin HALARA Planning
“We officially completed the Incore Sump Room Shielding project on nightshift on 4/29/23. There were ZERO safety or human performance issues during this implementation. The team came in under the 96-hour installation window and ~300 nRem under the dose allocation! Thank you to the ENTIRE NPO team for making this s HUGE success!!”
Sheri LProject Leader
“Everyone is very satisfied with the shielding that your company provided for the 360-inspection platform. It is already in-use.”
Rick SHealth Physicist
“You all came thru in a pinch, thanks again.”
Tim BALARA Supervisor
“I appreciate your professional effort and am glad NPO is working on this project.”

Custom Radiation Shielding Applications

Low Dose Waiting Area Shield Booth

Bruce Power collaborated with NPO to design a custom Low Dose Waiting Area (LDWA) Shield Booth to assist with reducing worker exposure leading up to a Major Component Refurbishment (MCR) project. The lead-in phase of the MCR project includes activities such as fuel removal, water removal from the primary heat transport system and moderator system, […]

Millstone Hot Spot Shielding

In 2025, Millstone Power Station faced a persistent dose rate challenge at a 45° elbow hot spot, where dose rates exceeded 20 Rem/hr. The existing temporary solution shielding blankets wrapped around the pipe were both visually unappealing and did not provide sufficient attenuation. Positioned overhead, the source posed unnecessary exposure to personnel working in the […]

Frisker Caves

NPO designs and manufactures a variety of frisker caves to reduce handheld Geiger Mueller (G-M) tube counters background radiation. The four featured designs range from heavy duty, maximum dose reduction caves to lighter and more mobile caves. T-Flex Variable Thickness Frisker Cave This frisker cave allows you to add and adjust the shielding thickness as […]

Rad Shipping Containers

NPO and Eichrom teamed up to launch a Rad Shipping System product for the radiopharmaceutical industry.  We worked closely with PET shipping experts to develop something that meets this industry’s unique needs.  Our emphasis was on durability, optimized shielding, hygienic, minimized footprint, ergonomic, and smooth operation.  Today our systems are used throughout the US. 10-30 […]

Oconee Heat Exchanger Skid Shielding

BEFORE AFTER Oconee Nuclear Station contacted NPO to develop a permanent shielding solution for the Supplemental Spent Fuel Cooling Heat Exchanger. The heat exchanger is located inside the truck bay with one side exposed to the main truck bay door at the Radiologically Controlled Area (RCA) boundary. The ALARA planners at Oconee wanted a permanent […]

Browns Ferry 360-Inspection Platform

Browns Ferry needed durable and effective floor shielding for the trough of their 360 cavity inspection platform. Like with most floor shielding applications, T-Flex® Bismuth was chosen because of its great attenuation properties relative to its cost. On top of the Bismuth shielding was a yellow slip-resistant tread surface to ensure workers would be able […]
