The following information was received from the State of
Texas via email:
On July 6, 2016, the licensee reported to the Agency [Texas Department of State Health Services] that one of its moisture density gauges had been run over and damaged, a Troxler Model 3411 containing 10 millicurie cesium-137 source and a 40 millicurie americium-241/beryllium source, serial number 10471 [at a highway construction site near Robstown, TX]. The technician had started the test and the source rod was extended into the ground. While the test was in progress the step-up grader hit the gauge, causing the source rod to bend. The technician stopped all work at the jobsite and setup a boundary of fifteen feet because the source rod could not be retracted. The technician called the RSO [Radiation Safety Officer] and RSO contacted a service company, Qual-Tek, to respond to the site to retrieve the gauge. The site foreman moved the road crew down the highway to avoid the gauge. The technician will stay at the site near the gauge until it is collected by Qual-Tek. [The RSO is investigating.] No member of the public or worker received any exposure as a result of this event. An update will be provided as obtained in accordance with SA300.
