| Title | Agreement State Report- Lost and Found Licensed Material |
| Event Description | The following information was received from the State of Louisiana by facsimile:
Event Location: The radiography crew was at the MARATHON PETROLEUM COMPANY REFINERY, 4663 West Airline Highway, Garyville, LA, St. John the Baptist Parish. The crew was in the refinery to do radiography weld testing. The weather for the day was stormy and raining. The crew was in the vehicle waiting out the weather when a tornado ripped the darkroom off of the company vehicle and took the camera and source with the darkroom. Event type: The lost/found gamma camera is an AMERSHAM, MODEL 880 DELTA, S/N4045 exposure device housing 39 Ci of Ir-192 AEA Technology sources, Model #A424-9, S/N # 1040C. The camera was located within the refinery boundary and appeared to be undamaged and the source remained in the shielded area. The camera was surveyed and only background radiation levels were detected. The camera was then transported to QSA Global on Langley Dr. in Baton Rouge, LA for leak tests, radioactive source and DU [Depleted Uranium] mechanical evaluation. [QSA Global] stated the device would be disassembled for the evaluation. If the results of the evaluation are negative, the equipment will be removed from service. The leak test results for radiation and DU were negative for removable contamination. Notifications: LDEQ [Louisiana Department of Environmental Quality] was notified of the lost/found radiography source in a QSA Global, Amersham Delta 880 gamma camera/source holder housing a 39 Ci Ir-192 source. The source exposure device was located within the refinery boundary. After a field evaluation, the exposure device was moved to QSA Global in Baton Rouge, LA for a professional mechanical evaluation. The results of the evaluation will determine if this equipment will be returned to service or remain out of service. Event Description: On May 28, 2014, [a senior trainer and business ops manager] called LDEQ and reported that a radiography crew dispatched to the Marathon Refinery in Garyville, LA had been hit by a tornado on the jobsite. The incident was at the Marathon Refinery, 4663 West Airline Highway in Garyville, LA. The tornado ripped the darkroom off of the truck with the gamma camera in the darkroom. After the storm had passed, the crew and the Marathon RSO surveyed the area in an attempt to locate the radiography source. The source and exposure device were located, field test/inspected for damage and radioactive contamination. When the equipment was deemed safe, it was transferred to QSA Global for a professional mechanical evaluation. ALL EQUIPMENT AND PERSONNEL APPEAR TO BE SAFE AND UNHARMED. LDEQ CONSIDERS THIS EVENT CLOSED. THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.
