In the late 1950s and early 1960s, two federal government-owned betatron particle accelerators were used at the Granite City Site, located in Granite City, Illinois, to x-ray uranium-238 metal ingots for the U.S. Atomic Energy Commission to check the quality of the metal and to detect metallurgical flaws before fabrication and machining were performed.

In 1992, DOE designated the site for remediation under FUSRAP. Several discrete, localized areas of contamination in the interior of one of the x-ray buildings were remediated in 1993. DOE certified that the site complied with applicable cleanup decontamination criteria and standards in June 1994 and released the property for unrestricted use.

No supplemental limits or institutional controls are in effect at the privately owned site, and DOE does not require on-site monitoring or surveillance. Legacy management activities consist of managing site records and responding to stakeholder inquiries.
