The following information was provided fro … The following information was provided from the state via email:</br>On December 12, 2011, the Agency was notified by a licensee that on Saturday, December 10, 2011, at approximately 1900 CST, there was a fire in the coker unit at their facility in Pasadena, TX. The RSO reported there were 4 fixed nuclear gauges on drums in the area of the fire. The gauges were Ohmart-Vega Model SH1G-1 and each contained a 300 milliCurie Cesium-137 source. Two gauges were directly in the fire and were damaged. The other two gauges were shielded from the fire by the drum they were mounted on and it has not yet been determined if they sustained any damage. The area was barricaded to prevent entry due to unsafe conditions caused by the fire (i.e. structural damage that has to be assessed, heat, ash/hydrocarbons). There were no radiation levels above background found during initial surveys from the barricade line and subsequent surveys conducted under the drums on the ground level and second level (areas where people will begin working). Higher levels will be surveyed prior to entry. The licensee has made arrangements with Ohmart-Vega for service to remove all 4 gauges once the area is safe.</br> </br>Gauge and Source Information:</br>Gauges: All Ohmart-Vega Model SH1G-1</br>Serial numbers:13543162, 13543163, 13543164 (in fire), 13543165 (in fire)</br>Sources: Cesium-137, 300 milliCuries each, SN same as gauge</br>Gauges installed March, 2010.</br> </br>More information will be provided as it is obtained.</br>* * * UPDATE FROM ART TUCKER TO JOHN KNOKE AT1612 EDT ON 06/21/12 * * * </br>The following information was provided from the state via email:</br>On June 13, 2012, the Agency was notified by the licensee that the four gauges involved in the fire on December 12, 2011, had been removed from the vessel and sent to their service provider.

A second source leak test was performed on the gauges once they were received at the service providers facility. The results were reported as less than the acceptable limit. On June 19, 2012, the service provider contacted the Agency and stated that while repairing one of the gauges containing 300 milliCuries of cesium - 137, their technician, the floor in the work area, and the work bench became contaminated. The area and the technician were decontaminated to background that same day.
