| ENS 43548 | 30 July 2007 05:00:00 | 10 CFR 20.2201(a)(1)(i) | Two Missing M114 A1 Elbow Telescopes | Location : Anniston AD (Army Depot), Anniston, AL Date reported to the licensee: 2 Aug 2007 by the Anniston AD RSO Licensed material involved: M114A1 elbow telescopes 2 each. NSN 1240-00-150-8889. Each elbow telescope contains 5.6 curies of tritium ( gaseous form). Historical information: On 30 June, two M102 howitzers left the maintenance repair facility at Anniston Army Depot from bldg. 418. Each howitzer contains a carrying case that contains the M114A1, M140 alignment device and M137 pantel telescope. The M102 howitzers and associated cases were transported to a contractor operated paint facility located on post in bldg 143. The howitzers were to be painted. When work was completed by the contractor, the howitzers and associated carrying cases (containing the tritium fire control devices) were moved to the Defense Logistics Agency (DLA) shipping area on or about July 23rd. During the week of July 23rd, DLA personnel inspected the howitzers and associated components prior to them being shipped. It was at this time that DLA discovered that the M114A1 elbow telescopes were missing from each of the respective cases. The other tritium devices in the carrying case (M140 and M137) were still present. The licensee RSO contacted Army CID on 3 August for assistance in investigating the loss of the devices. Army CID from Ft. McPherson, GA office will begin their investigation on Monday August 6th 2007. 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. This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source | ||
| ENS 47791 | 16 December 2009 04:00:00 | 10 CFR 20.2201(a)(1)(i) | Missing Chemical Agent Detector | When returning from deployment a Virginia National Guard unit discovered that they had lost a M43A1 Chemical Detector containing 250 uCi of Am-241. The unit searched the facility as well as a storage warehouse located in Richmond, VA for the device, but they were unable to locate it.
Retraction due to the detector found in the same location in a different Army unit. Notified the R1DO (Caruso), R3DO (Bloomer) and the FSME (McIntosh).

| ENS 52387 | 12 October 2016 19:24:00 | 10 CFR 20.2201(a)(1)(i) | Lost Shipment of Material Containing Tritium | USMC shipped the package (containing 45.06 Ci of tritium) via (common carrier) out of Hawthorne Army Depot, Hawthorne, NV on October 6, 2016 to MARCORLOGBASE, Director Fleet Support Dir Code 587, Radford Blvd, Suite 20320, Albany, GA. The package was signed for with initials and a signature showing delivery on October 12, 2016 at 1424 (EDT). There were several attempts of delivery before the package was delivered. The initials of who signed for the shipment cannot be traced to anyone and the signature is unreadable. (The common carrier) indicates delivery to the address of a receptionist. The package had UN2911 markings on opposite sides of the package. USMC RADCON conducted a physical search of USMC Albany locations to include the Post Office with no results. Defense Logistics Agency (DLA) Albany was contacted and DLA performed a physical search with no results. Also, another shipment from Hawthorne was sent out to a different location, which was received. This location was checked for receipt of the concerned package. On November 2, 2016, an Albany All Hands/Base wide official message was sent out regarding the package. The conclusion at this time is that the package is considered missing and likely somewhere at MCLB, Albany. The US Navy indicates that physical searches and base wide notifications continue in the effort to locate the package.

| ENS 53884 | 20 February 2019 14:30:00 | 10 CFR 20.2201(a)(1)(i) | Report of Loss of Ni-63 Sources Used in Improved Chemical Agent Monitors | The following was received from the licensee via e-mail: The concerned radioactive material is part of an Army Chemical Detection Equipment (CDE) and is called an Improved Chemical Agent Monitor (ICAM) NSN (National Stock Number) 6665-01-357-8502 and Chemical Agent Monitor (CAM), NSN 6665-01-199-4153. Each ICAM and CAM contains 10 mCi of Ni-63. The items with the radioactive material are under US Army NRC License 21-32838-01 issued to the Tank-Automotive and Armaments Command (TACOM). TACOM is located in Warren, MI. The reporting was based on 10 CFR 20.2201(a)(ii) (Reports of Theft or Loss of Licensed Material). Licensed material in a quantity greater than 10 times the quantity specified in Appendix C. The quantity specified in Appendix C is 100 microCi. One ICAM/CAM containing 10 mCi is 10,000 microCi. (The Radiation Safety Officer (RSO)) had reported nine CDE, but after confirming the serial numbers, we determined that one of the CDE (serial number 11769) was under another NRC license 19-10306-01 issued to the US Army Edgewood Chemical Biological Center (ECBC) located in Aberdeen Proving Ground (APG), Maryland. This report is for eight CDE under TACOM's NRC license. We have six ICAMs and two CAMs that are lost for a total of 80,000 microCi. The serial numbers for the ICAMs are Z47-M-13972, Z47-M-13526, Z47-M-01859, Z47-M-15832, Z47-M-21980 and Z47-M-18759. The serial numbers for the CAMs are Z16-M-01075 and Z16-M-01025. The ICAMs/CAMs are not known to leak and do not have a leak test requirement. The Ni-63 is inside the ICAM/CAM. (The RSO) was notified via e-mail on February 19, 2019, at 1545 EST, by the Army Rad waste agency (Joint Munitions Command (JMC) located in Rock Island, IL) of the following: 'A package containing nine each CDE was in route from APG, Maryland to Pine Bluff Arsenal (PBA), Alabama via (a Common Carrier) and was lost in the possession of (the Common Carrier). The CDE were being sent for demilitarization and eventual disposal of the Ni-63. The subject package was dropped off at (the Common Carrier) in Baltimore, MD on 26 Nov 2018. The tracking system showing the package as 'In (Common Carrier) Possession'.' Prior to the notification on February 19, 2019, JMC called PBA shipping and receiving. PBA personnel indicated that subject package was not received at their location. Also, APG personnel traveled to the (Common Carrier) facility where the items were dropped off. Personnel confirmed that the package was not at that facility. As of February 19, 2019, JMC indicated that (the Common Carrier) has not formally issued the a statement of loss, but that JMC will continue to track this for APG. It was a Local Project for JMC with ID number of APG 2018-001. On February 20, 2019, at 0847 EST, the (RSO) called (the Common Carrier) with the tracking number. (The RSO) spoke to (an individual) who indicated that a case was assigned to the shipment and a claim was put in. (The RSO) was put in contact with the Trace Department, and was then told that the shipment was considered lost. Shipments after 14 days are considered lost.
