| Title | Damaged Level Gauge |
| Event Description | The licensee (a foundry) reported damage to a level gauge (Texas Nuclear/Thermal Fischer Scientific containing a 100 millicurie source) due to a loss of area cooling. The cooling was lost when a unrelated fire damaged a water cooling pump in another part of the facility and radiant heat from the foundry process apparently caused damage to lead shielding around the gauge. The damage was discovered when the gauge started reading erratically. Investigation into the erratic level reading revealed a high radiation level in the vicinity of the gauge. The area in the vicinity of the gauge was cordoned off and assistance from the gauge manufacturer was requested. Shielding on one of the gauges was found to be partially melted and was assumed to have occurred when cooling in the area was lost. No contamination or damage to the source took place and no overexposure occurred. The damaged gauge and another gauge in the area were both removed and packaged for shipment back to the manufacturer for repair. |
