Title	Agreement State Report - Failed Nuclear Moisture/Density Gauge Handle Locking Mechanism
Event Description	The following information was received from the State of Arizona via email: During a routine inspection, the Arizona Radiation Regulatory Agency discovered that the handle locking mechanism of a CPN MC-3 Portaprobe (Serial # M39068944) containing 370MBq (10mCi) of Cesium-137 and 1.85 GBq (50mCi) of Americium-241/Beryllium, failed to function as intended. While testing the locking mechanism, the inspector was able to lower the Cs-137 source out of its housing, exposing the source, while the handle and trigger were in the locked position. The licensee was notified and the gauge was immediately placed out of service. The utilization log for the gauge was checked and it was determined that the gauge had not been in use for the previous 6 months. None of the users had reported issues with the gauge prior to that time. The licensee committed to having the gauge serviced as soon as possible. The Agency [Arizona Radiation Regulatory Agency] is continuing to investigate the event. The [Arizona] Governor's office and U.S. NRC are being notified of this event. [Arizona] First Notice: 17-011
