Title	Damaged Moisture Density Gauge
Event Description	The following event description was received via e-mail from the Virginia Radioactive Materials Program (VRMP): On June 29, 2021, at 1039 EDT, a representative of the VRMP received a report from a licensee's Radiation Safety Officer (RSO) via telephone call that a portable nuclear moisture/density gauge was damaged when hit by a car at a jobsite. The report indicated that a Troxler density gauge (Model 4640-B, containing 9 milliCuries of Cesium-137) was being used for asphalt testing when a car drove into the closed lane and hit the gauge. During the accident, the gauge housing was damaged but the source appeared to remain intact within the housing. The licensee's survey of the gauge yielded readings of 0.05 mR/hr at about 3-4 feet distance from the gauge. The gauge was taken to the licensee's office in its transport container and then was sent for further evaluation and leak testing on the morning of June 30, 2021. The VRMP is working with the licensee to obtain additional information. This report will be updated once the licensee's investigation is complete and the information is received. According to the RSO, no public exposure occurred. Virginia Event Report Number: VA21003
