Title	Stuck Shutter
Event Description	The following information was provided by the Mississippi Division of Radiological Health via email: During routine preventive maintenance on 1/23/2023, Tronox, LLC, discovered a stuck shutter on their Ohmart SHF-1-0, serial number 2641GK, 10mCi Cs-137. The shutter is stuck in its normal operating position. Using a Ludlum model 2241-2, serial number 313844 with a Ludlum Model 44-2 detector, the licensee measured 150 microrem/hr at 1 meter from the source and 1.4 millirem/hr at the surface. The gauge is mounted on an elevated platform in a process area. The area is not a routinely occupied work area and restrictions have been posted. The stuck shutter appears to be caused by corrosion. The licensee is working on a timeline for the repair. Mississippi Event Number: MS-230001
