The following was received from the State of
Texas via email:
On November 7, 2012, the Agency [State of Texas] was notified by the licensee that one of its Troxler model 3411B moisture/density gauges had been damaged. The gauge contained one 8 milliCurie cesium-137 source and one 40 milliCurie americium-241/beryllium source. The operator had stepped aside to a nearby wall to get location information. A bulldozer operator assumed that this meant that the test was finished and drove into the area, impacting the gauge. The gauge was not run over, but suffered a bent top and damaged electronics. The licensee performed a survey and determined that the integrity of the sources and shielding were not impacted. The licensee has performed a leak test and will be returning the device to the manufacturer for evaluation. The investigation into this event is ongoing.
