California Department of Public Health, Radiologic Health Branch (
RHB) via email:
The radiation safety officer for Giles Engineering contacted the RHB in Sacramento to report a lost/stolen CPN portable nuclear gauge, model MC-1, serial number MD71003961. This gauge contains two radioactive sealed sources: 370 MBq (10 mCi) of Cs-137 and 1.9 GBq (50 mCi) of Am-241.
The loss / theft occurred about on Friday August 9, 2024, while in Palm Springs at a job project. The CPN [brand] gauge was secured in the rear of the company pickup truck, locked inside the locked case. The gauge operator got stuck in deep sand at the job site, so he removed the security chain to get pulled out. He failed to re-secure the portable gauge to the pick-up truck and noticed it was missing while he was stopped at a local gas station. A police report was filed with Palm Springs police department. Maurer Technical Services and Instrotek were also notified.

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.
