The following information was received from the State of
Texas via email:
On August 3, 2015, the licensee reported to the Agency [Texas Department of State Health Services] that one of its technicians had run over and damaged a Humboldt 5001 EZ moisture/density gauge at a temporary job site in Belton, Texas. The gauge contained a 10 millicurie cesium-137 source and a 40 millicurie americium-241/beryllium source. The technician had started the test and the cesium source was extended four inches into the ground. The technician decided to move his pickup and while doing so he backed over the gauge and then pulled forward over it again. The source rod handle broke completely off of the gauge. A boundary around the gauge was marked and the licensee's radiation safety officer called a licensed service company. The service company responded and reported that the source was inside the gauge and not down in the hole, that it had apparently been pulled back into the gauge when it was run over. The service technician performed surveys and found no contamination. No member of the public received any exposure as a result of this event. No elevated exposures are anticipated for the technicians. An investigation into this event is ongoing. More information will be provided as it is obtain in accordance with SA-300.
