Title	Troxler Moisure Density Gauge Source Found Missing After Field Use
Event Description	A Troxler Moisture Density Gauge, Model 3430 S/N 22053, was evaluated in the shop after use at a temporary jobsite two hours earlier today in Royal Oak, MI. At the time the Authorized User (AU) attributed the inconsistent G-M readings to survey instrument error. However, further evaluation in the shop noted that the Cs-137 source (8 mCi) connected to the extendable source rod was missing. The licensee is enroute to the temporary jobsite in an effort to locate and recover the missing source. * * UPDATE AT 2000 EDT ON 6/25/07 FROM FRANK HENDERSON TO S. SANDIN * * * The licensee located and recovered the missing source. The source, shielded in a portable container of sand, is enroute to their facility in Plymouth, MI where the licensee will contact Troxler Labs for assistance. Established conference call between R3 (Shear, Gattone) and the licensee (Henderson). 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.
