The following information was received from the State of
California via email:
On 11/17/17, the RSO [Radiation Safety Officer] contacted RHB [CA Radiologic Health Branch] to report a stolen moisture density gauge. The stolen gauge is a CPN Model MC-1DR, S/N MD90209216, containing 10 mCi of Cs-137 and 50 mCi of Am-241. The user had taken the gauge home and left it secured in the back of his truck. The truck was parked at his residence . . .. According to the user, most likely between midnight and 5 AM of 11/17/17, the chain locking the gauge to the truck bed was removed and the case was dragged behind a building where the locks on the box were broken and the gauge was removed. The box was recovered without the gauge. [The] RSO had notified San Jose Police Department of this incident (Event # P173210429). RHB will be following up on this investigation.

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.
