| Title | Lost Chemical Agent Detectors |
| Event Description | The following summary of information was provided by the licensee via phone and email:
On February 18, 2025, Naval Sea System Command Detachment, Radiological Affairs Support Office was notified of the following information: On February 10, 2025, Marine Corps Logistics Command declared the loss of ten automatic chemical agent detector alarm (ACADA) systems (model no. NSN 6665-01-438-3673). Each ACADA contains 30 mCi of Ni-63. The loss was identified by the Marine Corps Logistics Command Radiological Control Office during October 2024 actions to terminate their Ni-63 permit (10-67004-T1NP). The last known reference to the detectors were during an October 2022 shipment from command distribution in Albany, GA to a force storage battalion where the detectors never arrived. Various interviews, search, and tracking efforts occurred with the detectors being removed from inventory in April 2024. No known exposures have occurred. To prevent recurrence, RFIDs are being utilized to ensure tracking and accountability along with adherence to GCSS-MC tracking standards.
The following information was provided by the licensee via email: The Naval Radiation Safety Committee (NRSC) requests to retract the report made 11 Feb 2025. The NRSC has determined that the automatic chemical agent detector alarm (ACADA) [systems], originally deemed as lost, were actually shipped to the Army Joint Munitions Command (Department of Defense Low Level Radioactive Waste Office) for disposal in March 2022. This is based on the discovery of errors noted on a shipping document that forwarded ACADAs from the Defense Logistics Agency to the Second Force Storage Battalion, which mistakenly led to an inventory error and ultimately the report to the NRC. Notified R1DO (Bickett), NMSS Events Notification (email), ILTAB (email). THIS MATERIAL EVENT CONTAINS A 'Less than Cat 3' LEVEL OF RADIOACTIVE MATERIAL Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
