Title	Agreement State Report - Nuclear Density Gauge Damaged by Vehicle at Worksite in Alaska
Event Description	The following information was received from the State of Washington via email: At about 1230 Pacific time an AECOM employee and authorized user of the nuclear density gauge backed a pickup truck into the gauge. The gauge was not in operation at the time and the rod was in the up and shielded position. The rod was not bent however the outside case of the gauge was damaged. Observation of the gauge indicated that the damage appeared to be confined to the outer casing and the electronic controls. The sealed sources did not have any visible signs of damage. The incident occurred at the Red Dog Mine in Alaska where [AECOM] was using the gauge under a reciprocity agreement with the NRC. A radiation detection instrument was used to confirm that the sources were not leaking and to check the area of the incident for any radiation. This survey indicated that the gauge was not leaking and that the area of the incident did not show any indication that the sources had leaked. Nuclear Density Gauge involved: CPN, MC Series containing two (2) sources; 0.01 Ci or 0.37 GBq Cs-137 and 0.05 Ci or 1.85 GBq Am-241. Incident Number: WA-16-028. * * UPDATE FROM FRED MERRILL (AECOM) TO DANIEL MILLS AT 1810 EDT ON 06/20/2016 * * * The licensee, AECOM, contacted NRC to report that the damaged device was being securely stored onsite at the mine until it can be shipped back to the manufacturer. The licensee also corrected the license number. Notified R4DO (Rollins) and NMSS (via email).
