| Title | Process Gauge Shutter Failed to Function Properly |
| Event Description | The licensee Radiation Safety Officer (RSO) determined that the shutter to a Berthold Model LB7440-D-CR process gauge with a 500 mCi Cs-137 source (source s/n: 031-08) did not open despite repeated attempts to cycle and lubricate the shutter opening mechanism. The RSO made this determination using instrumentation after rotating the shutter opening handle 180 degrees to the normally open position. The shutter had apparently become disconnected from the opening mechanism. The instrument is installed on a hopper dredge and is pointed down in an area not normally accessible by personnel.
A licensed Berthold technician has been contacted and will come to the site to repair the gauge. |
