gauge is a
Cs-137 Berthold Model
LB 7440D gauging device, serial number 1003-4-96, with an activity of 50 mCi. The licensee is reporting that the locking mechanisms for both shutters is disabled and won't allow for the shutters to close. The licensee is reporting that the gauging devices are still mounted to vessels. A Department inspector was dispatched to the facility on 02/17/22, and found the gauging devices as the licensee described. Dose rate readings using a NDS ND-2000A (calibrated 9/14/21) indicated readings as high as 1.8 mR/hr on the surface of the

gauges, attach a replacement shutter, and place the gauging devices in storage at the licensee's facility. This event is still under investigation by the
South Carolina Department of Health and Environmental Control.
