A radiographer was exposed to Ir-192 sources while working with industrial radiography cameras at a permanent fixed facility. The badge showed the individual involved received a dose of 0.07 Sv (7.2 rem). The radiographer potentially used different radiography cameras with different sources according to which shooting cell was being used on that day and the thickness of the material being exposed. As a corrective action, the radiographers will not be present inside the shooting cell when a source is outside of a shielded condition. Longer control cables will be used to reach the intended exposure location. Alternatively, the shooting cell will be accessed from the rear which will allow for shorter control cables to be used without being inside the cell. Indication lights will be placed on both sides of the wall to mark the entrance of the shooting cell. Personnel received training to prevent the recurrence of this event. The dose received exceeds the U.S. statutory limit for whole body dose of 0.05 Sv (5 rem). NRC EN55133
