CDT the agency [State of Texas] received a phone call from the licensee. The licensee stated that shutter on a fixed
gauge had stuck at approximately 1700
CDT on May 18, 2010. The
gauge houses a 50 milliCurie
Cesium (Cs) - 137 source. The licensee stated that shutter failed in the open position, the normal operating position for the
gauge, and that exposure rates in the area were normal. The
gauge is located high above the ground, on the side of a water tank. The licensee stated that they had contacted the manufacturer and have scheduled a repair of the
gauge within the next 30 days. The licensee stated that they were going to continue to use the
gauge, as it was in its normal operating state. The agency reminded the licensee that their license specifically states that they are to take the
gauge out of operation if it is in need of repair, and should they continue to use the
gauge, they would need to request an exemption from the agency. The licensee agreed to request the exemption so that they would not be in violation of their license.
The gauge is a Ronan Gauge S/N 936GG.
