AGREEMENT STATE REPORT - LOST/FOUND GAUGE

The following information was received from the Washington State Department of Health (the Department) via email:

"On March 7, 2025, at 1613 PDT, the Department was notified that a portable gauge (Troxler 3411-B) had fallen from a vehicle. This notification initially came from the Washington State Emergency Operations Officer of the Washington Military Department. The notification stated that the licensee had submitted a police report and was actively searching for the source.

"At 1633, the Department Emergency Response Duty Officer (ERDO) forwarded the notification to the Radioactive Materials Section Manager. At 1711, the Materials Section Manager contacted the licensee by phone to determine the scope of response necessary. The licensee informed the Department that the gauge was contained in a locked box and was believed to be lost or stolen. The licensee called back at 1716, informing the Department that the gauge had been found with the box locked, intact, and no signs of damage to the source contained within the shielded gauge. The gauge was found along the side of the road, in a ditch and away from any pedestrian traffic. No exposure is believed to have occurred to the public when considering the source was in a shielded position and inside of a locked Troxler class A container.

"The source was verified to be intact and sealed. Operational verifications of the gauge were performed, and the gauge is functioning normally. The gauge is in the possession of the licensee.

"A final report will be submitted to the NRC after the licensee has responded with corrective actions."
