On May 5, 2004, a Notice of Violation and Proposed Imposition of Civil Penalty in the amount of $7,500 was issued for a Severity Level III violation involving the failure to secure from unauthorized removal and failure to control and maintain constant surveillance of licensed material (150 millicuries of americium-241 in a thickness gauge, a generally-licensed device) in a controlled area, resulting in the loss of the gauge. Although the civil penalty would have been fully mitigated based on the normal civil penalty assessment process, a base civil penalty was assessed in accordance with Section VII.A.1.g of the Enforcement Policy to reflect the significance of maintaining control of licensed material.
