The following information was received via e-mail from the State of California:
On June 2, 2008, a routine inspection was performed on NOVA R&D, Inc. (RML # 5446-33). The licensee was issued a Notice of Violation for not performing the leak test on the sealed source (Am/Be, S/N 77C6654, 10 mCi on 3/7/90) after November 16, 2004. According to the written response, received August 14, 2008, the licensee performed a physical inventory of the radioactive sealed sources after the routine inspection and determined that the Am/Be sealed source was missing from the ground safe where the other sealed sources are stored. A thorough search for the source was conducted, but the Am/Be source was not located. The licensee is still trying to find the source in the facility and also searching for any documentation of proper disposal.
California Rpt #081408
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
