| Title | Agreement State Report - Two Missing Moisture Density Nuclear Gauges |
| Event Description | The following information was provided by the State of California via email:
On March 12, 2012, the RSO at Consolidated Engineering called the RHB [State of California - Radiological Health Branch] to report two missing moisture density nuclear gauges from their Oakland, CA storage facility, followed by an email (see below) detailing the events: On January 4 and January 5, 2012, as part of our bi-annual inventory, personnel performed an audit on a number of our nuclear gauges as required by our license. The inventory report was submitted to the RSO for review. Additional information was requested by the RSO on some of the gauges as is normal and customary. All of the gauges at that time were present and accounted for and were found to be satisfactory. On January 26, gauge # 0840 was signed in and out of our Oakland laboratory by one of our senior technicians. He subsequently used a different gauge in the days that followed. As part of my continuing duty to monitor locations and conditions of gauges, it became apparent to me last week that one of our gauges, #0840 was not in its designated storage location. In the course of calling all of our technicians and evaluating all of our storage locations, we called all gauges to be brought into our San Ramon office on Saturday March 10th. A second inventory was performed at that time on all of the gauges on our license. It was noted that gauge #0840 was missing as was gauge #5027, which was also stored in the Oakland location. We continued to exhaust all records, including sign-in and sign-out logs, report forms and checking with our license repair personnel and have concluded today that these gauges were more than likely stolen out of our Oakland office in January. Manufacturer Model # Serial No Last documented use of gauge Troxler 3411B T341 5027 06 January 2012 CPN MC3 M320400840 26 January 2012 The [source] quantities are as follows: CPN, 10 millicuries of Cesium 137 and 50 millicuries of Americium 241 Troxler, 09 millicuries of Cesium 137 and 44 millicuries of Americium 241. California Incident #5010-031212 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.
