On 9/12/2016 at approximately 1500 CDT, a portable gauge was struck by a private vehicle at a jobsite. This is preliminary information, and [The Oklahoma Environmental Agency] has not received a full report yet from the licensee. There does not appear to be any leakage or exposures from this incident.
Licensee: Oklahoma Department of Transportation (OK-15794-01)
Reported by: Larry Hawkins, ODOT RSO
Device: Troxler Model 4640
Isotope: 8 mCi Cesium-137
Location: Intersection of Highways 183 & 152, Cordell, OK
Description: Licensee reports that worker was using the gauge to take surface density measurements on an asphalt highway. The gauge shield was open, but the rod was not extended. A vehicle travelling approximately 25 mph ignored warnings, 'straddled' the highway centerline, and struck the gauge. The driver who struck the gauge left the scene after discovering what had happened.
The licensee reports that there was no contamination found on the highway or the gauge. The gauge sustained damage to the case and circuit board. The licensee stated that debris was cleared from the shield area and then the shield was closed. The gauge was shipped to Troxler. The licensee is waiting on leak test results, and will submit an incident report to the DEQ [Oklahoma Department of Environmental Quality].
