The following information was received via fax:
On 04/26/2013, the RSO for IRIS, was notified by one of his radiography crews working at the Marathon Refinery that a source was not retracting into the shielded area of the camera.
This incident involved a QSA Global Exposure Device, Model Delta 880, S/N D6458, loaded with an Ir-192 source. Associated equipment was used with the exposure device. The problem occurred when the crew used a magnetic source tube stand as opposed to a non-magnetic support stand.
Source retrieval was accomplished by the
RSO around 2:53 pm. Using safety equipment, maintaining a 2 mR boundary, and time, the highest exposure received was by the
RSO which was 75 mR. The other exposures recorded were from normal work activities. The Department [Louisiana Department of Environmental Quality] was notified after source retrieval was completed.
