| Event Description | The following information was provided by the California Department of Public Health, Radiologic Health Branch (the Department) via email:
On September 4, 2025, at 0930 PDT, the radiation safety officer (RSO) notified the Radiologic Health Branch that a CPN moisture density gauge had been stolen from a locked trailer at their construction jobsite. The construction manager noticed the company's trailer was unsecured and notified NMG Geotechnical. The gauge was secured within an internal locked cabinet inside the trailer, inside its locked transportation case that has the company name and contact number affixed. The gauge's trigger lock was confirmed to be engaged. The City of Carlsbad Police Department was notified, and a theft report was recorded. Maurer Technical Services was also notified. NMG Geotechnical will post a reward for information leading to the return of the stolen equipment. The Department will continue to investigate this event. " CA incident #: 5010-090425 Model: CPN MC-DRP Serial Number: Unknown Source: 10 mCi Cs-137, 50 mCi Am-241/Be 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.
