| Title | Agreement State Report - Lost Moisture Density Gauge |
| Event Description | The licensee provided the following information via facsimile:
On December 9, 2005 approximately between 11:50 a.m. and 12:15 p.m. [the gauge operator] lost a Nuclear Gauge (Troxler Moisture Density Gauge, Model 3430, s/n 35182, 8 millicuries Cs-137 and 40 millicuries Am-241:Be). [The gauge operator] was out at Del Webb Somersett, Village 8 to perform compaction tests with the Nuclear Gauge. [The gauge operator] arrived on the job-site and parked his truck at the intersection of Hidden River Way and Del Webb Parkway. He got his equipment ready to so he could begin to test the soil compaction. He took the gauge out of the safety box, and left it in the bed of his truck with the tailgate down. The contractor, ran into rock while excavating, and it was taking longer than normal to lay the pipe backfill. On and off for the next two hours [the gauge operator] watched from his truck. Lunchtime rolled around and the gauge operator left the jobsite for lunch. He did not put the gauge back in the safety box, or put his tailgate back up. This is the route that [the gauge operator] took to go to lunch. He took Del Webb Parkway East to Somersett Parkway. He took Somersett Parkway all the way to Mae Anne. After turning left onto Mae Anne he drove to KFC located in the Wal-Mart complex near McCarran Blvd. He went through the drive-thru at KFC, got his lunch and drove back to the job-site by the exact same route. When back on Del Webb Parkway he ran over a piece of steel and got out of his truck to see what he ran over. When he got out, he saw that the tailgate was down on his truck and that the gauge was gone. This was approximately 12:15 p.m. When [the gauge operator] saw the gauge was gone he got in his truck and retraced all of his steps looking for the gauge. He did not find it. The workers on the job site were asked if they had seen the gauge and no one had. The licensee notified the Reno Police Department and Washoe County Sheriff's Department. Event Report ID NV-05-006.
The gauge has been found and is now in the possession of the licensee. Some gauge electronics appeared to be missing, but the source appears to be intact. The gauge has been leak tested." Nevada has updated the Event Report ID Number from NV-05-006 to NV-05-009. Notified NMSS (Morell), R4DO (Johnson), and TAS (via E-mail). 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. |
