The following report was received from the Commonwealth of
Virginia via email:
On Saturday, December 13th [2014], a CPN MCIDR moisture/density gauge was run over at a temporary jobsite in Leesburg, Virginia (Battlefield Parkway and Sycolin Road). The licensee's authorized user was performing a test and walked about 20 feet away from the gauge. The general contractor's bulldozer operator did not see the gauge because the bulldozer blade was raised, which obstructed his view when driving the bulldozer up the slope.
The gauge was completely destroyed with the source in the transmission position. The authorized user contacted the construction testing services manager who then contacted the radiation safety officer. Both individuals arrived on scene and were able to retract the source into the shielded position using a pair of pliers. A radiation survey was performed at 1 meter indicating a reading of 0.4 mrem/hr. The gauge was then placed into the transportation case and returned to storage where a wipe test was performed. The wipe test has been sent to a licensed service provider for analysis and if no contamination is present, the gauge will be returned [pending final resolution].
The licensee submitted an incident report, which is under review by the [Virginia] Radioactive Materials Program. The incident and suggested corrective actions will also be re-examined during the next inspection.
