Title	Density Gauge Shutter Failure
Event Description	The following information was provided by the Texas Department of State Health Services (Agency) via email: On February 23, 2022, the Agency was notified by the licensee's radiation safety officer (RSO) that one of his crews had a failure of a shutter device on a Thermo Fisher Model 5190 density gauge containing a 20 millicurie (original activity) cesium - 137 source. The RSO stated that the shutter is a lead sheet that slides in a channel in front of the source. The RSO stated that the channel the sheet of lead slides through was damaged and the lead sheet will not stay in place if the gauge is moved (jiggled). It cannot be locked in the shield (closed) position. The workers removed the gauge and the pipe it was installed on and placed them both in storage. The RSO stated they were going to contact the manufacturer to have the gauge repaired. No individual received any significant exposure from this event. Additional information will be provided as it is received in accordance with SA-300. Texas Incident #: 9918
