| Title | Lost Tritium Exit Signs |
| Event Description | A major renovation was performed in two floors of Building 22 on the Eli Lilly Campus. This renovation was completed in December, 2010. An inventory of tritium exit signs was performed and eight exit signs on the two floors were found missing and presumed disposed of during the renovation. The exit signs each contained approximately 10 Curies of tritium. The licensee will perform wipe tests but expects negative results since the concrete surfaces were all covered with carpet, tile, or wall coverings.
Four Evenlite Model 201 serial numbers 57281, 59311, 57381, 57421 Four SRBT Model BX serial numbers C035796, C035795, C035790, C035789
The inventory of tritium exit signs was extended and eight additional tritium exit signs were missing. These additional exit signs were assigned to building 31 on the Eli Lilly Campus. This building had also been recently renovated. Each sign contained approximately 10 Ci tritium. Wipe tests in building 22 and 31 were performed with no activity detected. Notified the R3DO (Duncan), ILTAB (Allston), and FSME (McConnell). 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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf 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 |
