EN Revision Text: AGREEMENT STATE REPORT - DAMAGED TROXLER GAUGE
The following information was provided by the South Carolina Department of Health and Environmental Control (The Department) via email:
"The Department was notified on 11/18/22 at 1243 EST via telephone that a Troxler 3400 series portable moisture density gauge, serial number 33556, had been hit by a piece of construction equipment.
"The Troxler 3400 series portable moisture density gauge contains a maximum activity of 9 millicuries of Cs-137 and 44 millicuries of Am-241:Be. The licensee reported the source rod had been dislodged but had been successfully inserted back into the shielded position. A Department inspector was dispatched to the location on 11/18/22 and assisted the licensee in packing the damaged Troxler 3400 series device into the transport container. Dose rate readings using a ND-2000A survey instrument, calibrated 09/16/22 indicated readings as high as 30 mR/hr on the surface of the transport container and less than 1 mR/hr at 1 meter.
"The Troxler 3400 series moisture density gauge was transported and secured at the licensee's storage location and is awaiting shipment back to the manufacturer. This event is still under investigation by the South Carolina Department of Health and Environmental Control."

Records indicate the damaged gauge was not leaking and that the gauge/sources have been transferred to the manufacturer for disposal. This event is considered closed."

AGREEMENT STATE REPORT - LOST EXIT SIGNS
The following information was provided by the Colorado Department of Public Health and Environment via email:
The licensee discovered four tritium exit signs were lost. The exit signs are Isolite Corporation model 2040-50G-20WH signs containing 11.5 Ci of tritium (H-3) each. This is being reported under Colorado Regulations Section 4.51.1.1 (10 CFR 20.2202(a)(1)(i)).
Colorado Incident No.: CO220042
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.
