The following was received from the State of
Oklahoma via email:
Building and Earth Sciences has reported that a Troxler Model 3430 (S/N 36097) was stolen from a location in Ponca City, OK. The case was in the back of a truck and some time during the night it was opened and the gauge removed. The RSO is on the way to the site now, [the Oklahoma Department of Environmental Quality] will provide more information as it becomes available.
Troxler Model 3420 Density gauges typically contain Cs-137 8 mCi and Am-241/Be 40 mCi sources.
- * * UPDATE FROM MIKE BRODERICK TO JOHN SHOEMAKER AT 1100 EDT ON 6/9/2013 * * *
The State of Oklahoma reports that the gauge has been recovered and is now in the possession of the licensee. A private citizen found the missing gauge on the side of a road near the location where the gauge was stolen in Ponca City, OK. The source rod was still locked and it is believed that no exposures have occurred. The licensee will return the gauge to a secure storage location.

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.
