In the company’s own words

Mirion Technologies, Inc. (NYSE: MIR) is a global leader in radiation detection, measurement, analysis and monitoring solutions serving the nuclear energy, medical, defense and industrial markets. Headquartered in Atlanta, Georgia, the company operates through two reportable segments: Nuclear & Safety and Medical, with operations spanning twelve countries including the United States, Canada, the United Kingdom, France, Germany, Finland, China, Belgium, Netherlands, Estonia, Japan and South Korea.

The company's Nuclear & Safety segment provides radiation protection, measurement and monitoring solutions for nuclear power plants, research reactors, fuel cycle facilities and industrial applications.

The Medical segment delivers quality assurance solutions for radiation oncology, nuclear medicine equipment, radiopharmaceutical production systems and occupational dosimetry services. Mirion's medical solutions serve approximately eighty percent of global cancer centers, while its nuclear solutions are deployed in more than ninety-eight percent of nuclear power plants worldwide.

The company maintains a presence in over one hundred twenty countries and serves a diverse customer base including nuclear utilities, hospitals, cancer centers, government agencies, military organizations, research laboratories and industrial companies. No single customer represents more than five percent of consolidated revenue.
