The gauge had been mounted on a pipe near the well head on a well in La Salle County, Texas. The licensee is authorized to replace the roll pin so one of its trained technicians responded to the site and removed the gauge and repaired the roll pin. The technician found the shutter was closed when he surveyed prior to beginning work. The licensee also reported the technician found that the nuts had backed off of the bolts where the gauge was mounted to the pipe, so the gauge was not snug to the pipe. The licensee contacted Berthold to discuss effects of vibration as it pertains to this event (and potential effect for its other gauges mounted similarly) as well as the corrosion that was observed on roll pin(s). The licensee's determination was that there would not have been any exposures as a result of this event. The licensee will keep the gauge in storage until it can complete an evaluation of the gauge mounting location and the roll pin type for this and its other gauges. An investigation into this event is ongoing. Further information will be provided as it is obtained in accordance with SA-300.</br>Device/Source Information:</br>Berthold Model 8010 SN: 10455</br>20 milliCurie cesium-137 source: SN: 0330/12 (Eckert-Zigler Model CS7.P02)</br>Texas Incident Number: 9836odel CS7.P02)
