About Mirion Technologies
Mirion Technologies makes radiation detection and measurement equipment. It sells instruments, sensors, software, and services to nuclear power plants, national labs, hospitals, and defense customers, with much of its revenue recurring through dosimetry services, calibration, and replacement cycles. It is one of the largest dedicated suppliers in radiation safety.
Its products span radiation detection and monitoring systems for reactors and fuel facilities, nuclear instrumentation and control equipment, and dosimetry services that track worker radiation exposure. A medical business supplies quality assurance and dosimetry tools for radiation based cancer treatment.
Founded in 2005 and headquartered in Atlanta, Georgia, Mirion employs about 3,200 people and trades on the NYSE. Its installed base spans much of the world's operating nuclear fleet, giving it steady exposure to every reactor that runs, restarts, or gets built.
Mirion Technologies in the AI buildout
Mirion sits in the Power & Energy layer of the AI buildout as a picks-and-shovels supplier to the nuclear revival. AI data centers are pushing utilities and hyperscalers toward nuclear power, which means plant restarts, license extensions, uprates, and new SMR programs. Every one of those projects needs radiation detection, monitoring, and instrumentation, and Mirion already holds supply agreements with SMR developers. Its exposure grows with nuclear construction volume rather than with any single AI contract, so the buildout lifts demand indirectly but broadly.
MIR is tracked in Power & Energy, rated Growing on the AI Exposure leaderboard.
