On December 23, 2022, an authorized user of Nova Services, Inc. completed his use of radioactive Troxler 3430 gauge, serial number-32415 and returned it to the temporary storage location [Redacted] in Marina Del Rey, CA. The radioactive gauge was stored until the next time needed for for a work project in Marina Del Rey on January 24, 2023, at which time the authorized user discovered that the radioactive gauge was not in the storage unit, and reported the loss/theft to his Field Supervisor. The Field Supervisor reported the theft to an Inspector from the [Radiologic Health Branch - Radioactive Materials Inspection, Investigation, Compliance, and Enforcement Section] RHB-ICE Brea Regional office. The investigation is ongoing to determine the status of the radioactive gauge and will be reported to the local law enforcement agency, as well as contacting local newspapers in an attempt to retrieve the stolen radioactive gauge, and notifying local servicing vendors of radioactive gauges to be alert for the serial number of the stolen gauge in case it turns up for service. The gauge has not been recovered.

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.
