Title	Damage to Portable Moisture Density Gauge
Event Description	The following was received from the Virginia Radioactive Materials Program (VRMP) via email: On September 30, 2021 at 1530 EDT, the Virginia Radioactive Materials Program (VRMP) received a report via telephone from the licensee that a portable nuclear moisture/density gauge (Troxler Model 3430, serial number 25698, containing 8 millicuries of Cesium-137 and 40 millicuries of Americium-241/Beryllium) was damaged. It was hit by a compaction vehicle/machine at a temporary jobsite at approx. 1455 on 9/30/2021. The source rod was not out. The gauge housing was damaged but the source appeared to remain intact within the safe position. The licensee's survey of the gauge yielded readings of approx. 2.0 mR/hr at about 6 inches from the gauge. The readings were at or below background (0.02 mR/hr) along a 4 foot radius around the gauge. The gauge was transported to the licensee's office in its transport container. A survey was also performed on the ground and the reading was reported as background. The gauge will be tested for leakage and will be sent to the Troxler Electronics Laboratories for evaluation. The RSO indicated the gauge is not functional. The VRMP is working with the licensee to obtain additional information. This report will be updated once the licensee's investigation is complete.
