| Title | Agreement State Report - Lost / Recovered Moisture Density Gauge |
| Event Description | On September 25, 2006 at approximately 6:15 P.M., a gauge user from Geo-Environmental, Inc., had returned to the office to return Troxler gauge 3440, S/N 34036 (9 mCi Cs-137, 44 mCi Am-241:Be) to it's storage location, when he noticed that the gauge was missing and immediately contacted the RSO to report the incident. After the RSO had spoken with the gauge user, the RSO received a call from the office manager that the gauge had been recovered by the Irvine Police Department on Jamboree Rd. in Irvine near the intersection of Jamboree Rd., and Richter Ave. The gauge was returned to the Geo-Environmental, Inc., office at approximately 6:45 P.M. The gauge most likely was out of the control of the licensee for approximately one hour. The gauge case was intact with a single scuff mark. The gauge was inspected by the licensee and found to be intact. The RSO then contacted RHB [DELETED] by phone to report the incident by voice mail. At approximately 9:00 A.M. on September 26, 2007, [RHB] spoke with the RSO about the incident and instructed him to have the gauge inspected and leak tested by a service provider and the RSO stated that he would take the gauge to Maurer Technical Services to be inspected and leak tested. [RHB] also instructed the RSO to provide, within 30 days, a written report, in accordance to 10 CFR 20.2201 (a)(1)(i). The RSO stated that the gauge user involved was allowed to transport the gauge in an open bed truck and with two chains and two locks and with two locks on the gauge case. He also stated that the gauge was transported with only a single lock to secure both chains.
CA report number: 092607 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. |
