Title	Agreement State Report - Troxler Moisture/Density Gauge Run Over by Bulldozer
Event Description	The following was received from the State of Louisiana via email: On July 2, 2014, the CRSO [Corporate Radiation Safety Officer], for Terracon Consultants (TCI) notified LDEQ [Louisiana Department of Environmental Quality] that a moisture density gauge being used at one of their projects was run over by a bulldozer. The source was left unattended when a bulldozer ran over the gauge and damaged the housing. They are conducting an investigation to determine the cause of the incident. It appears that it was human error. The sources were leak tested and TCI is waiting for the results of the test. The unit was surveyed and it appears the sources were not leaking. Results will be forwarded to NMED as an update when the information is obtained. All equipment involved is isolated and is not a threat to the public. There is no threat to TCI personnel and it appears to be safe. The damaged gauge was a Troxler, Model 3430, S/N 26346, loaded with 8 mCi of Cs-137 and 40 mCi of Am-241/Be. The gauge housing was damaged, but there was no indication the radioactive sources were compromised or leaking. The sources were isolated and leak tested.
