04/17/2006 On April 17, 2006, a Notice of Violation and Proposed Imposition of Civil Penalty in the amount of $3,250 was issued for a Severity Level III problem involving three violations.

Specifically, the authorized user failed to adequately lock a transport case onto the bed of his truck and close the tailgate. As a result, the case containing a licensed gauge fell off the truck and was in the public domain for approximately 6 days before it was recovered.

01/04/2001 On January 4, 2002, a Notice of Violation was issued for a Severity Level III violation involving the licensee allowing an individual to work as an authorized nuclear pharmacist (ANP) without notifying the NRC within 30 days licensee after the date that the licensee allowed the individual to work as an ANP. Although a civil penalty would normally have been proposed in this case, the NRC exercised discretion in accordance with Section VII.B.6 of the Enforcement Policy and refrained from issuing a penalty. Discretion was warranted because the NRC concluded that the potential safety consequences were low, the pharmacist was forthcoming during the NRC's inspection, the Radiation Safety Officer (RSO) promptly initiated supervision of the pharmacist upon being informed of the inspection finding, and all individuals involved accepted responsibility for the violation and cooperated during the investigation.

ORDER 05/23/2008 On May 23, 2008, a Confirmatory Order (effective immediately) was issued to Global X-ray & Testing (Global) to confirm commitments made as a result of an Alternative Dispute Resolution (ADR) settlement agreement. NRC identified four violations during inspection and investigation involving: 1) a willful failure to provide the NRC with complete and accurate information; 2) the failure to prevent workers from resuming work after their pocket dosimeters were found to be off-scale; 3) the failure to ensure that a radiographer was providing personal supervision of the radiographer's assistant through direct observation of the assistant's performance of radiographic operations; and 4) allowing an individual who was not wearing a personal dosimeter to conduct radiographic operations. In response to these violations, the licensee requested ADR. As part of the agreement, licensee agreed to additional management review that will include developing procedures for additional oversight of offshore radiographic operations, obtaining an agreement with lay-barge operators that will address radiographic operations, incidents, and oversight; field audits of lay-barge radiographic operations by licensee management, making arrangements for NRC inspection of radiographic activities on U.S. owned lay-barges, implementation of training on potential consequences for violation of NRC regulations, and delivering a personal letter to each employee regarding the consequences of wrongdoing. Global also agreed to obtain an NRC license with special license conditions for radiographic operations in offshore waters. In exchange for Global's extensive corrective actions and most notably in consideration of costs associated with obtaining an NRC license, the NRC agreed to eliminate the civil monetary penalty.
