Operation Emery BANEBERRY, 1970

Operation Emery was a group of 16 nuclear tests conducted by the United States in 1970-1971. Yucca Flat, Area 8 hosted the Baneberry shot of Operation Emery on December 18, 1970. The Baneberry 10 kiloton test detonated 900 feet below the surface, but its energy cracked the soil in unexpected ways, causing a fissure near ground zero and the failure of the shaft and cap. A plume of fire and dust was released three and a half minutes after ignition, raining fallout on workers in different locations within Nevada Test Site. After dropping a portion of its load locally, the hot cloud's lighter particles were carried to three altitudes and conveyed by winter storms and the jet stream to be deposited heavily as radionuclide-laden snow in Lassen and Sierra counties in northeast California, and to lesser degrees in southern Idaho, northern Nevada and some eastern sections of Oregon and Washington states. Two US Federal court cases resulted from the Baneberry event. Two NTS workers who were exposed to high levels of radiation from Baneberry died in 1974, both from acute myeloid leukemia. The district court found that although the Government had acted negligently, the radiation from the Baneberry test did not cause the leukemia cases.
