The following update was received from the State of Texas via email:
On January 29, 2019, the licensee's Radiation Safety Officer (RSO) reported to the [Texas Department of State Health Services] that after further investigation two additional gauges were found on December 19, 2018, with shutters stuck in the open position. Open is the normal operating position. The gauges are Ohmart Vega model SH-F1B serial number 8431CN and 8443CN, both containing 100 mCi of cesium (Cs)-137. The RSO stated he discovered the additional shutter failures after reviewing reports received on January 21, 2019. The gauges are located on towers, not easily accessible, and are unlikely to cause unintended exposure. The RSO has contacted a service company and is anticipating the repairs completed to all three gauges in the next week. The RSO intends to apply grease to O-rings to prevent moisture from entering and fouling the shutter mechanism.
