Title	Radiography Source Failed to Retract
Event Description	The following was received by email from the Commonwealth of Pennsylvania: The licensee reported that on February 12, 2021 while using a QSA Global Model 880, Serial # D15520, containing a 128 Curie source of iridium-192, the source failed to fully retract and lock. The technicians secured the area by adjusting their 2 mR/hr boundaries to an unshielded source distance and immediately contacted their company designee. Once on scene, the designee surveyed the scene and device and found elevated readings. Working the crank handle back and forth several times he was able to return the source to the secured and locked position. The device was taken back to the licensee's storage vault in Williamsport, PA for inspection. The cause of the incident is believed to be cold temperature and freezing of the lock mechanism. The Radiation Safety Officer (RSO) subsequently investigated the incident and found that neither the radiographer nor the assistant radiographer had been performing proper radiation surveys during the workday which would have identified the lock failure sooner. As a result, the radiographer received a dose of 876 mR. We are still awaiting a dose on the assistant radiographer. Corrective actions include retraining all radiography employees to follow proper procedure. Also, both the radiographer and assistant radiographer are no longer employed by the licensee.
