AGREEMENT STATE REPORT - LOST/STOLEN TROXLER GAUGE
The following is a summary of information reported by the Florida Department of Health via email:
Terracon Consultants reported a Troxler 2440 gauge was stolen from a truck while the truck was parked at a residence in Brandenton, Florida. The gauge was stolen around 0930 EDT on 9/24/2020. The gauge was secured with two chains and two locks by the driver of the truck. The local police department has been notified. The gauge contained a 8 mCi Cs-137 source (S/N: 75-1841) and a 40 mCi Am241:Be source (S/N: 47-15958).
Florida Incident Number: FL20-109
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.
