| Title | Density Gauge Shutter Failure |
| Event Description | A density gauge with a 4 milliCurie Cs-137 source was identified to have a stuck shutter. The gauge is an Ohmart Vega Model SHF1A-0, S/N 0964CO, and is permanently installed on a process line in an isolated tower area. This event did not result in exposure to any personnel. The licensee barricaded the area, which read less than 1mR/hr. The licensee plans on having the gauge repaired by the manufacturer. |
