Event Text
DENSITY MEASURING DEVICE FELL INTO THE GULF OF MEXICO. DIVERS WILL RETRIEVE IT MONDAY MORNING.

A density measuring device stripped off its wireline and fell into the Gulf of Mexico. The well is between 25 to 50 miles offshore from New Orleans. Chevron Oil owns the Well. Well # 1 in the Gulf of Mexico is located at OCSG 13982. The density measuring device contains a 17mCi cesium-137 source and the source is double encapsulated within another holder. The density measuring device is approximately 1.688 inches in diameter and 40 feet long. The device is at a depth of 123 feet of water on a hard bottom next to the well head (light ocean currents in the area). The make of the density measuring device is a Gammatron, Model "CSV", and its serial number is "V948". A special diving crew will go down in the morning to retrieve the density measuring device. The diving crew has been briefed that they will be retrieving a radioactive source.
