## Description

On July 11, 2012, the NRC issued a Notice of Violation to Gamma Irradiator Services (GIS) for a Severity Level III violation. The violation involved the failure to limit licensed activities to Category 1 self-shielded irradiators, as required by Condition 9 of GIS's NRC license No. 37-30850-01. Specifically, on May 2, 2003, February 25, 2005, June 15, 2007, and May 19, 2009, GIS performed maintenance activities on a JL Shepherd Model 81-22 irradiator, which is not a self-shielded (Category I) irradiator but, rather, a panoramic (Category II) irradiator.
