The licensee reported that a technician had a
Troxler moisture/density
gauge, Model #3430 (Serial #19531), locked in the trunk of his car. The technician's brother took the car for a "joy ride" and the car was reported to the Fairfield police as
stolen. The brother was pulled over by the police roughly 1/2 hour later. The
gauge was recovered undamaged and still locked in the trunk of the car. The licensee reported that they lost possession of the
gauge for no more than 1/2 hour and that the brother probably did not intend to steal the
gauge. The
gauge contains 27mCi of
Cesium 137 and 132 mCi of
Americium 241. The Fairfield police, bomb squad, and the local
FBI responded to the event.
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.
