November 3, 2021 — Mirion Technologies, Inc., a global provider of detection, measurement, analysis and monitoring solutions to the medical, nuclear, defense, and research end markets, today announced the acquisition of CHP Dosimetry, a U.S.-based distributor of dosimetry services. The acquisition closed on Nov. 1, 2021.
Headquartered in Clinton, Tenn., CHP Dosimetry provides dosimetry services for medical practices, veterinary offices, universities, and government agencies, as well as industrial and environmental companies. CHP Dosimetry was founded in 2004 and is a veteran-owned small business (VOSB). The company recorded $1.2 million in revenue for the year ended Dec. 31, 2020.
CHP Dosimetry is a current customer of Mirion, with CHP Dosimetry offering customers access to several Mirion-branded solutions including its flagship innovation, the Instadose dosimetry monitoring platform. Instadose dosimetry is a SMARTER personal dosimeter technology that eliminates the need to collect and return badges every wear period. Providing on-demand and automatic dose reads and insights, Instadose dosimeters enable instant access to current and historical exposure data and cumulative dose insights, along with the ability to make account, location, device, and wearer changes online within minutes.
"As the sole supplier of dosimetry offerings for CHP Dosimetry, acquiring the company’s distribution channels marks a natural progression for our business," said Lou Biacchi, President of Mirion Dosimetry Services. "We are excited to directly serve CHP Dosimetry’s existing customers who we expect will continue to utilize Mirion’s robust dosimetry products."
Mirion provides personal radiation monitoring services and dosimetry solutions for a wide range of applications. Personal dosimeters are typically worn by individuals (clipped to their collar, torso, waist, wrist or worn as a ring on their finger) who work with or around sources of ionizing radiation and are used to measure, record, and track the radiation dose they are exposed to while performing their job.
