The following was received from the
California Department of Public Health Radiologic Health Branch (
RHB) via email:
On 10/21/19, the RSO [radiation safety officer] contacted RHB to report a stolen moisture density gauge. The gauge is a CPN Model MC1Elite, S/N 30492, containing 50 mCi of Cs-137 and 50 mCi of Am-241. It was stolen on 10/21/19 around 0230 [PDT] from the back of a truck parked at the gauge user's residence. The gauge was being used at a temporary job site near the user's residence and it was stolen by cutting the locks securing the gauge. The licensee provided video footage of the crime taking place from a video camera at the user's residence. The licensee had contacted the Salinas Police Department to notify them of the incident (Case #19-101002). A flyer has been posted with a reward for the safe return of the gauge. 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.
