Title	Agreement State Report - Unable to Retract Source Due to Damaged Guide Tube
Event Description	The following information was obtained from the State of Tennessee via email: On December 6, 2015 at approximately 1300 EST, an exposure device D6032, (880 Delta) containing Source S/N SE4869, 50 Ci of Se-75, fell from its position on top of a flange assembly approximately six feet to the finished floor. Upon impact, the guide tube was crimped preventing the source from being able to return to the camera. The source was able to be returned to the collimator reducing the radiation present. Technicians secured a true two mR boundary and notified plant safety personnel and the RSO. The lead technician onsite was source retrieval certified and took charge of the retrieval process. The source was further shielded in a larger diameter pipe and covered with sand bags to reduce radiation levels. Using a pair of pliers, the technician was able to 're-round' the guide tube opening to allow the source to be returned to the camera. The guide tube, camera and control assembly was taken out of service pending inspection. The guide tube was damaged beyond use; the source 'pigtail' and control cable were inspected and tested using a no-go gauge. The guide tube was removed from service and the control assembly will be sent to the manufacturer for further evaluation (ball end connector). Source retrieval technician received a total dose of 150 mR during the event. Tennessee Report No.: TN-16-012
