On October 20, 2020, the NRC issued a Notice of Violation to International Isotopes, Inc. (INIS) for a Severity Level II problem involving two violations. Specifically, (1) INIS failed to have appropriate administrative procedures that assured the completion of safety evaluations as required by 10 CFR 31.13(c)(3); and (2) the INIS radiation safety committee inappropriately approved procedures that changed the conditions of the NRC license and that decreased the effectiveness of the radiation safety program. The NRC considers these violations to be significant because the inadequate procedures directly contributed to a significant contamination event at the University of Washington's Harborview Medical Center on May 2, 2019.
