The following was received from the State of
Texas via email:
On August 10, 2016, The Agency [Texas Department of State Health Services] was notified by the licensee that during a daily inspection, the shutter on an Ohmart Vega SH-F1 nuclear gauge could not be operated. The gauge contains a 10 millicurie (original activity) source. The shutter is operated by an pneumatic operator. The operating mechanism is located inside a steel box to help prevent foreign material from interfering with the shutter operation. It appears that over time, moisture was being trapped in the box causing the operating rod connecting pin to rust and break. The shutter cannot be moved. It is in the open position which is the normal operating position for the shutter. A service company has been contacted and will be on-site on August 11, 2016, to repair the gauge. The gauge does not present an exposure hazard to the licensee's workers or members of the general public. Addition information will be provided as it is received in accordance with SA-300.
