The following information was provided by the Florida Bureau of Radiation Control (BRC) via email:
"BRC received notification that a Troxler gauge, model 3430 (8 mCi Cs-137, 40 mCi Am-241-Be), was impacted by a bobcat construction vehicle. The yellow case of the gauge is significantly damaged, but the licensee states the source rod was successfully retracted. The area has been roped off with a 20 foot radius. An inspector has been assigned for immediate response."

AGREEMENT STATE REPORT - LOST EXIT SIGNS
The following is a summary of information provided by the Colorado Department of Public Health and Environment via email:
The licensee reported that three exit signs, containing a total of 52.53 Ci of tritium, were lost in Denver, Colorado.
Manufacturer: SRB Technologies
Model number: BX-20-WH
Event report ID number: CO250039
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.
