| Title | Fixed Gauge Found with Shutter Open While in Storage |
| Event Description | The licensee was evaluating a fixed gauge in storage for possibly returning it to service when they discovered that the gauge's shutter was stuck open. Temporary lead shielding was installed and the licensee is in the process of contacting the manufacturer in order to have the device repaired and/or the source removed.
The device is an Ohmart SHRM L-200, S/N 3269, containing 35 milliCuries of Cs-137. It was removed from service and has been in storage since 1994. The gauge was positioned face down such that radiation surveys did not detect that the shutter was open. The licensee does not believe that any personnel received any significant exposure since the storage area is ground level (no basement) and has limited access (locked). |
