Sterigenics International, a portfolio company of GTCR, has bought Gammarad. No financial terms were disclosed. Based in Bologna, Italy, Gammarad is a gamma sterilization provider.


DEERFIELD, Ill.–(BUSINESS WIRE)–Sterigenics International LLC, a leading global provider of contract sterilization, gamma technologies and medical isotopes, and a portfolio company of GTCR, today announced it has acquired Gammarad, Italy’s leading gamma sterilization provider.

Gammarad, established in 1969 and located in Bologna, Italy, provides gamma irradiation sterilization services for the biomedical, pharmaceutical, food packaging, and cosmetics industries.

“With over 4 million cubic feet of processing capability, this is an important piece to the Sterigenics strategy to continue to expand our global footprint and market position as the leading solutions based provider in contract sterilization,” said Philip Macnabb, President of Sterigenics International LLC. “With this second Gamma irradiation site in Western Europe, Sterigenics can now offer redundancy to our current customers as well as those of Gammarad.

The Gammarad acquisition follows an active year of expansion for Sterigenics. In March, Sterigenics acquired Food Technology Service, Inc., and in August acquired Nordion, Inc., creating the only vertically integrated sterilization company in the world.
