ENS 5379113 December 2018 16:12:00Braun Intertec Corporation reported an event of the inability to retract a 1.44 TBq (39 Ci) Ir-192 sealed source (QSA Global, Inc. Model A424-9, SN 67476) which occurred at a temporary job site near Belfield, ND at approximately 4:02 pm CST on December 12, 2018. While performing radiography using a QSA Global, Inc. Model 880 Delta (SN D9541) exposure device on a pipe section resting on a stand, the pipe fell from the stand and kinked the guide tube. The radiography crew was unable to retract the source and immediately expanded the public dose boundary to an actual 2 mR/hr distance and maintained continuous surveillance and contacted their RSO for guidance. The RSO arrived on site the same day at approximately 8:45 pm CST and completed the source retrieval at approximately 9:45 pm CST. The sealed source was successfully retrieved into the exposure device. The maximum exposure readings from the direct reading exposure devices of the radiography crew and retrieval personnel was 3 mR. The crank assembly and guide tube were taken out of service. Visual inspection noted no defects to the pigtail assembly. North Dakota Event: 180003
