| Title | Lost Sr-90 Source |
| Event Description | During an underway replenishment in the fifth fleet area of operations, a storage box containing a CH53 helicopter blade with an in-blade inspection system (IBIS) was dropped over the side and is irretrievable due to the depth of the water. The IBIS contained a 500 microCuries Sr-90 source.
The licensee has notified their NRC Project Manager (Seeley). 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.
