Title	Loss of Seven Curie Source from Radiography Camera
Event Description	The licensee was conducting non-destructive testing (radiography camera x-ray) on an oil platform in the Gulf of Mexico. While the radiography was taking place at night, over grating, the pigtail disconnected from the camera and dropped through the grating into the Gulf of Mexico. The area where the source fell is about 6 miles from shore, East Cam 33 CS, and the depth of the water was about 40 feet. Licensee is not going to try to retrieve the source. The camera source is 7 Ci of Ir-192, s/n QD-1302. The camera is a Spec 150, s/n 814. THIS MATERIAL EVENT CONTAINS A "CATEGORY 3" LEVEL OF RADIOACTIVE MATERIAL Category 3 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 some hours. It could possibly - although it is unlikely - be fatal to be close to this amount of unshielded radioactive material for a period of days to weeks. These sources are typically used in practices such as fixed industrial gauges involving high activity sources (for example: level gauges, dredger gauges, conveyor gauges and spinning pipe gauges) and well logging. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf Although IAEA categorization of this event is typically based on device type, the staff has been made aware of the actual activity of the source, and after calculation determines that it is a Category 3 event. Note: the value assigned by device type "Category 2" is different than the calculated value "Category 3
