| Title | Loss Tritium Exit Sign |
| Event Description | The following information was received via email:
The Michoud Assembly Facility [(MAF)] operates under an NRC general license. The MAF currently has a project being performed by a subcontractor to replace approximately 28 Tritium exit signs. On 7/6/2020, an employee noticed that one Tritium exit sign [source activity of 3.0 Curies] was not in the location of its last inventory. Further investigation into the incident and discussions with the project manager indicated that the exit sign was most likely removed by the subcontractor performing the demolition work on-site. The project manager notified the subcontractor to investigate the incident further, at which time the subcontractor reported the Tritium exit sign had been disposed of at the Construction and Debris (C&D) waste [facility] in the Gentilly Landfill LCC 1 located at 10200 Almonaster Blvd. in New Orleans, LA 70127. 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.
