| Title | Agreement State Report - Damaged Moisture-Density Gauge |
| Event Description | The following was received from the State of Texas via email.
On July 23, 2018, the licensee reported that one of its Troxler model 3430 moisture/density gauges (SN: 68529) had been run over and damaged by a dozer at a temporary job site. The licensee's technician was performing a moisture test when he saw a dozer moving backward into the area and toward the gauge. The technician yelled at the dozer driver but was unable to get his attention and there was not enough time for the technician to move the gauge. The gauge was severely damaged. The 40 milliCurie americium-241/beryllium source (SN: 47-21269) remained secure in its shielding. The source insertion rod was bent and broken and the 8 milliCurie cesium-137 source, which was still attached to the rod, could not be retracted. The licensee wrapped the exposed cesium source in lead blankets and placed the gauge back into its transport case. The area and dozer tracks were surveyed--there were no readings above background. The exterior of the transport case was surveyed and the highest reading was 0.4 mR/hr at the blanketed source. The damaged gauge was transported to the manufacturer's service center where a technician made the determination it was not repairable. The licensee is storing the gauge at its facility until arrangements can be made for disposal. An investigation into this event is ongoing. More information will be provided as it becomes available in accordance with SA-300. Texas Incident #: 9600 |
