On 4/15/2024, the California Office of Emergency Services (OES) forwarded a report from Testing Engineers, Inc. The radiation safety officer (RSO) notified OES that one of their nuclear gauges (CPN MC-1, serial number MD71108870 containing 10 mCi of Cs-137 and 50 mCi of Am-241) was stolen from a storage unit that is located within a public storage facility in Concord, CA. The gauge was stolen from the storage unit at an unknown time between 04/13/2024 and 04/14/2024, but was discovered missing at 1541 [PDT] on 04/15/2024. A car was used to ram the door of the storage unit, and a pry bar was used to remove the gauge from a locked cabinet. Local law enforcement was notified, and a reward was posted on Craigslist, Facebook, and Nextdoor for the safe return of the gauge.
RHB will investigate the incident."
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.
