On November 1, 2001, a Notice of Violation was issued for a Severity Level III violation involving the failure to secure from unauthorized removal or limit access to licensed material (one-curie molybdenum-99/technetium-99m generator) in an unrestricted area and failure to control and maintain constant surveillance of licensed material. Although a civil penalty would normally be proposed by the civil penalty assessment process, the NRC exercise discretion in accordance with Section VII.B.6 and did not propose a penalty because the NRC concluded that the incident was an isolated occurrence caused by personnel error.
