DESCRIPTION OF CIRCUMSTANCES UNDER WHICH THE LOSS OR THEFT OCCURRED The detectors are believed to have been disposed of as radioactive waste. Detailed disposal records for the detectors have not been found. They are classified as missing due to the lack of disposal documentation.
A STATEMENT OF DISPOSITION, OR PROBABLE DISPOSITION, OF THE LICENSED MATERIAL INVOLVED The detectors were probably disposed of as radioactive waste at the Barnwell Low-Level Radioactive Waste Disposal Facility located in South Carolina.
EXPOSURES OF INDIVIDUALS TO RADIATION, CIRCUMSTANCES UNDER WHICH THE EXPOSURES OCCURRED, AND THE POSSIBLE TOTAL EFFECTIVE DOSE EQUIVALENT TO PERSONS IN UNRESTRICTED AREAS There is no known exposure to individuals. It is believed that the detectors were disposed of as radioactive waste and therefore, no inadvertent radiation exposures are believed to have occurred as a result of this situation.
ACTIONS THAT HAVE BEEN TAKEN, OR WILL BE TAKEN, TO RECOVER THE MATERIAL All actions related to this event are complete.
PROCEDURES OR MEASURES THAT HAVE BEEN, OR WILL BE, ADOPTED TO ENSURE AGAINST A RECURRENCE OF THE LOSS OR THEFT OF LICENSED MATERIAL A review of current Exelon proceduralized requirements for exempt quantity SNM controls has concluded that existing requirements are adequate to prevent recurrence of this event.
