Title	Damaged Humboldt Moisture Density Gauge.
Event Description	Representative of SCI Engineering located in St. Charles, MO reported the following incident: At approximately 1030 CST at a commercial job site in Warrenton, MO., a caterpillar truck ran over a Humboldt Model # 5100C moisture density gauge. The Humboldt case was cracked. The area around the damaged gauge has been roped off (50 feet from the gauge). The licensee did not know if the source rod had been broken off. R. M. Wester & Assoc. should be arriving shortly to take surveys and then take appropriate action based on their survey results. The gauge contains 11 millicuries of Cesium-137 and 40 millicuries of Am-241/Be. As far as the licensee knows there is no release. Warrenton is located about 30 miles West of St. Louis off of Interstate Highway 70. * * Update at 1447 EST on 12/22/04 by William Guerdan to MacKinnon * * * R. M. Wester completed surveys and the results of the surveys are: no leaks and no contamination of the gauge. Both sources are intact and the area around the gauge is clean. The vehicle that ran over the gauge is also clean. R. M. Wester & Assoc. have taken possession of the gauge and they will take back to their St. Peter, Mo. office and perform a leak test of the gauge. Leak test of the gauge should be completed by the close of business today, 12/22/04. R3DO (L.Kozak) and NMSS (S. Wastler) notified.
