| Title | Helicopter Integrated Blade Inspection System Source Lost |
| Event Description | On 12/13/11, after a Marine Corps CH53 Helicopter training flight at 1900 PST it was determined during a post flight inspection that the 500 micro-Curie Sr-90 integrated blade inspection system (IBIS) source was missing. The flight originated on Marine Corps Air Station Miramar. During the flight the helicopter flew over the pacific ocean then to and over Camp Pendleton before returning to Miramar.
An investigation into the event is ongoing. The results of the investigation will determine what actions are taken to recover the source. 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 |
