Title	Damaged Gauge
Event Description	The following information was provided by the California Radiation Control Program via email: [The licensee] contacted the California Department of Emergency Services to report a moisture density gauge was run over at a worksite. The gauge was a CPN MC-3, S/N M30019316 (10 mCi cesium-137, 50mCi americium-241/beryllium). After placing the gauge with the cesium-137 source in the locked and shielded position on the ground, the operator went to retrieve some equipment from his vehicle when the bulldozer ran over the gauge snapping the source rod off and damaging the plastic housing on the top of the gauge. The bottom of the gauge was intact, and the americium-241/beryllium source was still attached and undamaged. The licensee was instructed to place the gauge in the transport case and wait until the Riverside County Department of Environmental Health inspector arrived at the scene. Upon arrival, the inspector performed a radiation survey (model and serial number not reported) and found there were no significant radiation levels above background. The gauge will be transported to Maurer Technical Services for disposal. The investigation into the incident by the California Department of Public Health is ongoing. California 5010 Number: 080125
