Title	Damaged Moisture/Density Gauge
Event Description	With the moisture/density gauge still on the ground after performing a standard count, the licensee Radiation Safety Officer backed over the gauge with his pickup truck. The source was not exposed at the time and the source remained shielded. Damage noted to the gauge was a broken shaft that sets the depth of test which is also part of the handle along with some surface scarring to the gauge housing. The gauge was checked with a survey meter for leakage from the sources. At one meter the survey meter reading was less than 0.2 mrem/hr which is comparable to a non-damaged gauge. A leak test wipe was also performed and sent to Humboldt Mfg. for measurement. The gauge was transported and placed in its secure storage location until a determination has been made on how repairs will be accomplished. The gauge is a Humboldt Model 5001 moisture/density gauge containing 10 mCi Cs-137 and 40 mCi Am-241/Be.
