Title	Gauge Shutter Failure
Event Description	The following information was provided by the Radiation Health Branch of the Kentucky Department for Public Health and Safety (The Department) via email: The Department was notified on 11/12/2025, by the radiation safety officer (RSO) from Big Rivers Electric Corporation, that during a routine six-month inventory/shutter checks, two sources were identified to have problems with the shutters closing. Both [gauges] measure density in the scrubber material and are mounted on piping. No exposure is possible unless the piping or gauge is removed. Primary action is to notify personnel and modify the red tag system to indicate that until this is resolved, no maintenance can be allowed on the piping because the shutters on the gauges cannot be safely closed. Until further notice, the piping where these gauges are mounted cannot have any maintenance activities performed on them. Red tag authorities should make note that the gauges cannot be red tagged because the shutters do not close. Maintenance will be performed on the gauges by an authorized contractor. Gauge 1 information: Manufacturer: Kay Ray Model number: 20493 Serial number: 7062BP Activity: 10 mCi Cs-137 Gauge 2 information: Manufacturer: Ronan Model number: SA8-C5 Serial number: 2104CP Activity: 20 mCi Cs-137
