"On 11/10/19, California Office of Emergency Services (OES) contacted RHB [Radiologic Health Branch] to report a stolen moisture density gauge. This gauge is a CPN Model MC-3, S/N M311000525 containing 10 mCi of Cs-137 and 50 mCi of Am-241. The gauge was stolen while momentarily unattended in the licensee's facility parking lot.

RHB will be following up on this investigation."

California report: 111017

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.
