Title	Non-Agreement State Report: Failure of Source Connection
Event Description	The following summary was received from the licensee via email: On 1240 EDT on 7/29/2020, a Radiographer for Diamond Technical Services discovered that the source for a radiography projector disconnected from the drive cable. The radiation barriers were expanded, additional shielding was laid down, and site personnel were notified to clear the immediate area. No personnel were exposed at the time of the discovery. The source projector is a Sentinel 880D, S/N: 12726 with an Iridium-192 source with an activity of 52.5 Curies. The Operations Manager and Radiation Safety Officer traveled to Alma, WV from their offices in Blairsville, PA with emergency equipment and radiation safety supplies. At 1715 EDT, the source was retrieved and secured in its shielded position. There were no indications of excessive exposures. The preliminary cause of the source disconnection was determined to be fatigue failure. The components will be shipped to QSA for manufacturer evaluation and inspection.
