| ENS 53436 | 20 May 2024 19:38:00 | Agreement State | Agreement State Report - In-Line Density Gauge Stuck Shutter | The following information was received via E-mail: On May 31, 2018, the Department (PA DEP Bureau of Radiation Protection) was notified by the licensee that a malfunction of a roll pin on a shutter handle occurred at a temporary jobsite in Eighty Four, Pennsylvania. It is initially reportable per 10 CFR 30.50(b)(2). A roll pin, which holds the shutter handle to the shutter shaft on a Berthhold Model LB 8010 in-line density gauge containing 20 milliCuries of cesium-137 became sheared off during an attempt to move the shutter to the open position, rendering the gauge unusable. The gauge is currently being stored at their Punxsutawney, PA location. The shutter is in the closed position and the gauge is out of service awaiting repair from the manufacturer. There was no other damage to the gauge. No overexposures have occurred. Radionuclide: Cs-137 Manufacturer: Berthold Model: LB 8010 Serial Number: 10485 Activity: 20 mCi The cause of the event has been attributed to normal wear and tear on the gauge. A reactive inspection is planned by the Department. PA Event Report ID No: PA180013 | ||
| ENS 55755 | 22 February 2022 06:00:00 | Agreement State | Density Gauge Shutter Failure | 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 | ||
