After attempting to retract the source during radiography operations, the radiographer noticed elevated radiation levels. The radiographer set up a boundary and notified the
RSO. The
RSO determined that the source was not fully retracted but was able to retract the source. The
RSO was in a 40 mr/hr area for about 5 minutes. The licensee will send the camera to the manufacturer for repair.
