Title	Agreement State Report - Radiography Camera Source Unable to Be Retracted
Event Description	The following information was provided from the State of Louisiana via facsimile: IRISNDT dispatched a radiography crew to Marathon Petroleum on September 5, 2012. The crew set up and began work around 6:30 am. The crew worked with a camera, associated equipment, and a collimator for hours before there was a problem. [At 1045 CDT] the source setup was about 15 feet up above the ground in the pipe rack when the source would not return into the shielded position. After several attempts to retrieve the source, the RSO was notified. The crew was instructed to secure the barricade at the 2 mR distance and maintain observing the area until the RSO could arrive. The RSO arrived and secured the source into the exposure device's shielded position. The equipment, QSA Global Delta 880, s/n# D6460, the source is s/n# 86363B ...Ir-192, last leak tested on 08/07/2012. The investigation concluded a gear in the crank assembly was damaged and it caused the drive cable to jam. The assembly was red tagged and removed from service. Event exposures were 29 mR [Radiographer Trainer], 6 mR [Radiographer Trainee] and 2.4 mR [RSO]. Louisiana Event Report ID No. LA1200004.
