Title	Agreement State Report - Moisture Density Gauge Struck by Vehicle at Construction Site
Event Description	The following was received from the state via fax: The on-duty State Response Coordinator (SRC) for the Wisconsin Department of Health Services (DHS) received a phone call at approximately 3:30 am that a moisture density gauge had been struck by a motor vehicle. The incident occurred at a road construction site near 1221 Northport Drive, Madison, WI. The gauge was in use with the operator in contact with it, when a car veered out of traffic into the construction lane. The operator was forced to jump out of the path of the vehicle, leaving the gauge. The vehicle struck the gauge, shattering the housing. The source rod with the Cesium-137 source detached from the housing. The Americium/Beryllium source remained within the housing. The SRC and licensee's RSO responded to the scene to supervise source recovery. The Cesium source was leak tested in-situ and determined to be intact. Surveys were performed in the affected area, with no contamination detected. A portion of the housing designed to hold the retracted Cesium source rod was found partially intact. The Cesium source was placed within the cavity and securely taped. The housing assembly was placed in the transport container for transport back to a licensed service provider for assistance with disposal. The driver who struck the gauge has yet to be located by the police. The licensee will be submitting a 30 day written report concerning this event. Event Report ID Number: WI110017
