Title	Agreement State Report - Damaged Moisture/Density Gauge
Event Description	The following information was received from the State of California via email: On 03/29/16, the California Office of Emergency Services (OES) contacted the RHB [Radiation Health Branch] via an email to notify them of a damaged moisture/density gauge. The gauge was a Troxler gauge, Model 3440, S/N 38618 containing 9 mCi of Cs-137 and 44 mCi of Am-241. The gauge had been run over by an excavator while the operator was taking a reading along the side of the road where the incident occurred. Per the licensee, the Cs-137 source was in the shielded position (at the time of the incident readings were taken over a standard block for counts) when the gauge was damaged. The licensee stated that a 20 foot area was cordoned off until the gauge was removed. Fire Department personnel were at the scene. Per the licensee, a Pacific Nuclear Technology (PNT) RSO arrived at the site, and confirmed a survey meter reading of 0.5 mRems at one meter from the gauge, which is considered normal for this type of gauge. It was also noted that the Cs-137 and Am-241 sources were intact. Survey of the area after removal of the gauge indicated background readings. The gauge was placed inside the transit cage and returned to the licensee's storage location. A leak test will be performed and the gauge will be disposed of in the near future. RHB will be following up on this incident. California 5010 Number: 032916 / Kleinfelder
