| ENS 52078 | 8 July 2016 23:30:00 | 10 CFR 30.50(b)(2) | Source Failed to Retract Into Radiography Camera | While conducting radiography at a field location in Indiana, the radiographer determined that the source could not be retracted. He immediately contacted the company's radiation safety officer (RSO), located in Pennsylvania. The RSO, who is licensed to retrieve sources, directed the radiographer to establish a 2 mR/hr boundary and await his arrival. Additionally, another crew was dispatched to assist the original crew in maintaining the boundary secure. Upon the RSO's arrival, the RSO and radiographers determined that the source was still in the collimator. They then used sandbags to reduce the work area dose rates. The RSO was able to retrieve the source and return it to the shielded position in the camera. The RSO conducted field testing and found no mechanical issues with the camera and could not replicate the problem. The RSO believes the problem was due to a source misconnect. The camera is currently enroute to the company's Ohio facility for additional testing prior to returning it to service. The RSO received 2 mR during the retrieval. The radiographer and assistant radiographer received 20 mR and 5 mR, respectively, during the retrieval. The camera was a QSA 880 Delta containing a 55 Ci Ir-192 source. No members of the public received any dose due to this event. |
