On April 3, 2025, the NRC issued a notice of violation and proposed imposition of Civil Penalty - $9000 (Notice) to St. Louis University (licensee) for a Severity Level (SL) III problem. The SL III problem involved the licensee’s failure to secure licensed materials from unauthorized removal or access as required by 10 CFR 20.1801; and the failure to perform radiation surveys before disposing licensed material by transfer to an authorized recipient, as required by 10 CFR 20.1501(a). These failures resulted in a unit dosage of radium-223 being disposed in the normal trash. In addition, the Notice included an SLIV violation of 10 CFR 35.40(a) that was dispositioned as a non-cited violation, consistent with Section 2.3.2.b of the Enforcement Policy.
