Title	Troxler Density Gauge Damaged by Soil Compactor
Event Description	While preparing to take a soil density measurement, a soil compactor operator backed up and ran over the Troxler density gauge, damaging the casing of the density gauge. The gauge was examined and inspected and the top of the case was cracked, however, the plunger and source appeared to be intact. The gauge was isolated and returned to its protective case. The gauge was subsequently sent for leak testing to Qual-Tech in Idaho Falls. The gauge has been quarantined and isolated pending the results of the leak testing. Density gauge information: Troxler model 3430 containing Am-241 - 40 milliCuries and Cs-137 - 8 milliCuries * * UPDATE AT 1205 EDT ON 05/18/16 FROM ANDREW TILSKALUS TO S. SANDIN * * * Qual-Tech replaced the top cover and leak tested the gauge satisfactorily. The gauge was returned to the licensee and placed back in service.
