The licensee completed testing at jobsite and thought he had stowed his
moisture density gauge (
Troxler model 3340, SN 25752, 8 - 10 mCi Cs-137/ 40 mCi Am-241/Be). He left the jobsite in Shingle Springs, CA, and while in-transit to Elk Grove, CA (via highway 50) the technician heard a thud from outside of the vehicle but did not think anything of it. When the technician arrived at his residence he noticed the truck's tailgate was down and realized the
gauge was missing. He backtracked to the jobsite and was unable to locate the
gauge on the highway or at the jobsite. The technician notified the
RSO, the Elk Grove Police Department and the
California Highway Patrol. The State will provide more information as it becomes available.
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.
