The State sent this event via fax:
Radiography was being performed by American Engineering and Testing at Midwest Tank in Big Lake,
Minnesota when after performing an exposure, the 41.4 curie,
Ir-192 source would not retract back into the camera. The radiographer attempted numerous times to retract the source and was unsuccessful. The radiographer and radiography's assistant performed surveys and reset the boundaries. The

RSO had performed the source retrieval and it was secured back in the camera at 1420.
MDH received a call at 1530 providing notification of the incident. Preliminary cause was a kink in the guide tube.
