Title	Agreement State REPORT- Stuck Shutter
Event Description	The following information was provided by the Nevada Division of Radiation Health via email and phone: On June 18, 2024, Nevada Goldmines - Elko, discovered a failed shutter while conducting required 6-month shutter checks on a Berthold LB 7440 fixed gauge in the open position. In place radiation surveys were conducted to verify safety until a contractor would be available to remove the gauge and move it to storage. All readings were normal. The licensee coordinated with Radiation Technology Inc., (RTI) to remove the gauge and move it to the authorized storage area pending decision to repair or dispose of the gauge. RTI conducted onsite leak checks and results were less than 0.005 microcuries. A second set of leak check samples were taken to be returned to RTI lab for verification. A radiation survey following deinstallation confirmed them to be background. The gauge was removed from service, plates placed over the open window to provide shielding, and the device with plates covering the window was placed in storage. Surveys of the storage area show increase in radiation consistent with adding a new gauge to the job box, with the highest radiation level being 79 microR/hour at 12 inches. Gauge Information: Model: Berthold LB 7440 Serial number: 3015 Activity: Cs-137 (150 Ci) Nevada Item Number: NV240004
