The ultimate proving ground for more than 50 years.


From outer space to the front lines, the Boeing Radiation Effects Laboratory (BREL) prepares your product for the harshest environments imaginable.

Run by our team of world-class scientists, the laboratory leads the industry in simulating the effects of destructive radiation on critical materials and electronics. BREL then uses these simulations to test, evaluate, and qualify products for use in situations where failure is not an option.

With many facilities available within Boeing and through other agencies, the laboratory is capable of simulating almost any radiated environment. From natural space radiation exposure to nuclear weapon-system threats, you can be confident that wherever your product is going, it will be prepared.

Specific testing abilities range from determining the effects of atmospheric neutrons on commercial avionics systems to assessing total ionizing dose and single-event effects of cosmic rays and natural space radiation on electronics. The laboratory also offers other services such as instrumentation and test equipment for measuring the electrical parameters of circuits before and after radiation exposure.

Since 1963, BREL has helped companies protect their people and products around the world and into space. Contact us for information about contracting opportunities, capabilities, and pricing.

    Electronics test laboratory

    Our state-of-the-art electronics test laboratory is located in the same building as our radiation facilities, enabling quick and efficient analysis at less time and cost. The lab is equipped with automated testers for analog, digital, and mixed-signal integrated circuits, as well as Boeing's General Purpose Test Equipment pool, which includes an inventory of data acquisition and measurement equipment across the company with the latest bandwidth and sophistication technology.

    Our lab meets all traceability requirements of the National Institute of Standards and Technology, as well as being ISO 9001 certified.

    Material surface damage testing

    At the heart of BREL are Boeing’s combined radiation-effects test capabilities.

    Our comprehensive set of UV, vacuum UV, proton, and electron sources spans a large energy spectrum capable of testing for material surface damage effects that can impact design. Our lab is equipped with multiple chambers and, because each has a different and unique purpose, we can offer combined effects testing all in one location, testing articles measuring up to 18 inches diagonally. Further test capabilities include reflectance spectroscopy, electrostatic discharge, and in situ electron-proton beam spectrum measurements.

    Shielding-produced secondary radiation effects

    Over the past several decades, the BREL team has built a strong partnership with the Neutron and Nuclear Science (WNR) facility at Los Alamos National Laboratory. In addition to our many other partners in the industry, Los Alamos expands our capabilities by using their MCNPX radiation transport code to enable shielding design and analysis.

    This capability allows us to test secondary radiation generation within shielding material, including neutrons resulting from high-energy cosmic rays, electrons, and protons. In addition to MCNPX testing, the BREL team is also using this ability to develop lightweight shielding design tools for customers around the world.


    Since its creation, BREL has led the industry in radiation testing and evaluation. And over the past several decades, Boeing has continued to invest resources into the laboratory to ensure that our equipment and our people remain ready at the cutting edge of aerospace.

    This ongoing evolution has allowed the BREL team to expand its abilities, and its place at the forefront of the industry, with millions of dollars’ worth of investments. These upgrades include new optical spectroscopy capabilities, beam characterization and dosimetry, test chamber enhancements, and automated testers for analog, digital, and mixed-signal integrated circuits.

    BREL has also been improved with multichannel, high-bandwidth portable controllers for data acquisition to further enable single event effects testing, as well as accelerator upgrades and new control and safety systems. Our most recent addition added a subterranean open-air enhanced low dose rate sensitivity irradiation facility in 2015.
