Title	Damaged Moisture Density Gauge
Event Description	Radiation Health Physics consultants, R.M. Wester, notified the NRC of an event in the State of Missouri that resulted in damage to a Humboldt Soil Density Gauge (Model EZ 5001, S/N 693) containing 40 mCi Am-241/Be and 10 mCi Cs-137. The gauge is licensed to Jacobi Geotechnical Engineering. The consultant stated that the event took place at a construction site in Pezley, MO. The gauge was run over by a backhoe. There was some damage to the plastic housing of the gauge. The source rod was undamaged. The source rod was wipe tested with negative results. In addition, soil samples at the incident location also tested negative. R.M. Wester has taken possession of the gauge and will ship it to Humboldt for repairs. The licensee notified the NRC Resident Inspector. * * RETRACTION BY JAMES PYATT TO KARL DIEDERICH ON 1/10/08 AT 1630 * * * Wester responded to the site at the time of the accident, and found no indication of leakage.
