| Event Description | The following information was provided by the Ohio Department of Health (ODH) via email:
The licensee informed ODH on Wednesday, 1/4/2023, that one of the IMS Model 5321 gauges at its plant in Canton, Ohio has a shutter stuck in the open position. The gauge contains nine [Cesium] Cs-137 sources with a maximum activity of 10 Curies each and each source has its own shutter. The other eight shutters are operating normally. The licensee tried cycling the stuck shutter and activating the air cut-off/bleed-off valve, but the shutter remained open. The manufacturer has a technician scheduled to come in Saturday, 1/7/2023, at the earliest to make the repair. The gauge is contained inside a caged area with a keycard lock mechanism and motion sensor. Since the gauge shutter cannot be closed, licensee management has sent a communication out to all badged employees who have access to the cage informing them to not enter until the manufacturer can come onsite and make the necessary repairs. The normal operating state for this device is with the shutter open. ODH has authorized the mill to continue operations until the manufacturer arrives to make repairs and standard radiation boundaries will continue to work for protection.
