About Us
Our History
Alpha-Omega Services, Inc. (AOS), a US-based corporation, has delivered innovative solutions to the radiation therapy field for over 50 years. Founded in 1973, AOS initially focused on the sales and installation of radioactive sources and the remanufacturing of cobalt-60 teletherapy units for both medical and industrial applications. Soon after, AOS expanded into source manufacturing, introducing iridium-192 platinum-sheathed radioactive sources for medical implants and a proprietary line of brachytherapy applicators and accessories.
As a leader in the medical sector, AOS partnered with industry leaders like Elekta Instruments, AB (1988), Varian Medical Systems (1999), Sirtex Medical (2001), and Nucletron BV (2011). In the mid-2000s, AOS developed compact, heavily shielded transport packages for Type B radioactive materials, achieving US NRC Certificate 9316 in 2012 for models AOS-100A, AOS-100A-S, AOS-100B, AOS-050A, and AOS-025A.
