Title	Agreement State Report - Lost Moisture Density Gauge
Event Description	The following information was received from the state of California via e-mail: On August 8, 2011, Mr. Todd Rucker, RSO from Pavement Engineering, Inc., notified RHB [Radiation Health Branch] Sacramento that one of their moisture-density gauge operators lost a gauge at their job site on August 6, 2011 at approximately 4:30 am. The gauge had been borrowed from A. Teicher & Son, Inc., License No 4030-34. The gauge was used on a job site on HWY 70 in Yuba County, near the town of Olivehurst, CA. The lost gauge is a Troxler, Model 4640-B, Serial number T464 1793. This model moisture density gauge has an 8 mCi Cs-137 source. California event number: 080611 * * UPDATE FROM EPHRIME MEKURIA TO CHARLES TEAL ON 8/17/11 AT 1731 EDT * * * Pavement Engineering has found the lost gauge. Notified R4DO (Hay), FSME EO (Watson), ILTAB (Johnson), and Mexico via fax. 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.
