AGREEMENT STATE REPORT - LOST EXIT SIGNS
The following is a summary of information received from the Colorado Department of Public Health and Environment via email:
Four exit signs, each containing 12.57 curies of tritium (50.28 curies total), were determined to be lost by the licensee.
Manufacturer: Isolite Corporation
Model Number: SLX60
Colorado event number: CO240025
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.

AGREEMENT STATE - STUCK OPEN SHUTTER
The following information was provided by the Georgia Radioactive Materials Program via email:
"[The licensee's] radiation safety officer (RSO) reported that a shutter had failed in the open position during a routine shutter check on October 9, 2024. This was a Ohmart/Vega [gauge containing] 15 mCi of Cs-137, serial number: 32153cp. The licensee barricaded the area around [the gauge]. A service repair request and leak test are currently in progress. The RSO stated that the licensee checked [radiation level] at 1 foot away, and found [exposure rate] to be 0.2 millirad per hour and presents no risk to health and safety."
