| Event Description | The following was received via e-mail from the California Department of Public Health, Radiological Health Branch (RHB):
On April 30, 2021, [The] ENGEO [Radiological Safety Officer] RSO contacted RHB to report a stolen moisture density gauge, a Troxler, Model 3440, S/N 26157 containing licensed material 9 mCi of Cs-137 and 44 mCi of Am-241. The gauge was stolen from one of their storage locations (Extra Space Storage). The gauge was last in their physical possession on April 22, 2021, and was secured in the facility at approximate 1430 PDT. The facility is secured by a common gate with access granted with an access key code with security cameras that log entering and exiting the facility. The storage unit was secured by a keyed master lock, and the equipment was locked to the inside of the unit with a chain and secured with at least 1 master lock. Since April 22, 2021, [the] staff has visited the unit on a couple of occasions, however [the staff] was not concerned at the time when the equipment was not observed in the unit which is common as the equipment is used during the day on a regular basis and also due to the lock to the unit being intact (showing no signs of forced entry). On April 29, 2021, the individual who the equipment is assigned to, returned to pick up the gauge and noticed someone had removed it. It was determined that no one from their company removed the gauge from the storage unit after it was secured on April 22, 2021. [The] licensee was unable to view security footage due to privacy of other customers. [The] licensee was told by the manager that he reviewed all footage of their staff entering and leaving the facility between April 22 and April 29 and he observed the staff return the gauge to the unit on April 22, and leave without the gauge in his vehicle after he secured it in the storage unit. [The] licensee has conducted an internal investigation into the location of the gauge and determined that no one with their organization removed the gauge in question. This appears to be consistent with the reported observations of the facility manager's review of security footage. [The] licensee has notified Rohnert Park Police Department of the stolen gauge (police report #21-1838). A cash reward has been offered for the safe return of the gauge. RHB will be following up on this investigation. California Report Number: 043021 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.
