| Title | Agreement State Report - Two Nuclear Gauges Involved in Fire |
| Event Description | The following report was received via E-mail:
On November 30, 2017, the Agency [Texas Department of State Health Services] was notified by the licensee's consultant that two nuclear gauges were involved in a fire on November 28, 2017. The consultant stated they could not gain access to the gauges until this date. The gauges are Thermo Fisher model 5203 gauges containing a two (2) curie (original activity) cesium-137 source. The consultant stated the dose rate on one of the gauges was reading 180 millirem an hour on a preliminary radiation survey. This dose rate appears to be higher than normal. A contamination survey was performed in the area of the gauges, but the results were not available at the time of the report. The gauges are located 20 - 30 feet above the ground and do not create an exposure risk to any individuals. Additional information will be provided as it is received in accordance with SA-300. Texas Incident #: I-9524
The following information was received via E-mail: The licensee has provided the following additional information: The source holders are visibly intact, however they are black with soot. Both of the gauges were surveyed. For B-1228 the readings are normal but B-1227 has a localized spot on the lower left-hand location of the shield where the readings are 180 mR/hr at contact and 14 mR/hr at 1 ft. Additional shielding has been attached to the lower left hand location of the shield to reduce the dose rate to 3 mR/hr at 1 ft. Sealed Source leak tests have been performed and the results will be communicated as soon as they are assayed. No personnel (member of the general public or radiation workers) have been within 5 feet of either source due to the unsafe structural conditions due to the fire. Additional information will be provided as it is received in accordance with SA-300. Notified the R4DO (O'Keefe) and NMSS Events Notification (via e-mail).
The following information was received via E-mail: The licensee reported that the results of the leak test performed on the two gauges indicated the sources were not leaking (less than 0.0001 microCi). Additional information will be provided as it is received in accordance with SA-300. Notified the R4DO (O'Keefe) and NMSS Events Notification (via e-mail). |
