Texas via email:
On October 30, 2013, the Agency [Texas Department of Health] was notified by the licensee that while conducting routine maintenance checks on a Texas Nuclear model 5196 nuclear gauge containing a 20 milliCurie cesium137 source, the shutter was found stuck in the open position. The licensee lubricated the operating shaft and attempted to close and reopen the shutter. While attempting to reopen the shutter, the operating rod for the shutter broke. The licensee determined the gauge is in the open position, which is the normal operating position for the gauge. The licensee has contacted the gauge manufacturer and will either repair or replace the gauge. No individual received any additional exposure as a result of this event. Additional information will be provided as it is received in accordance with Reporting Material Events SA-300.
