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.
