Atomic Test Effects In The Nevada Test Site Region published by the AEC in 1955, a document with a civilian audience in mind. Account of NTS fallout in 1955 (PDF) Study Estimating Thyroid Doses of I-131 Received by Americans From Nevada Atmospheric Nuclear Bomb Test, National Cancer Institute (1997) Rice, James.
Sedan was a thermonuclear device with a fission yield less than 30% and a fusion yield about 70%. [3] [4] According to Carey Sublette, the design of the Sedan device was similar to that used in the Bluestone and Swanee tests of Operation Dominic conducted days and months prior to Sedan respectively, and was therefore not unlike the W56 high yield Minuteman I missile warhead.

The knowledge gained provided data to prevent nuclear yields in case of accidental detonations—for example, in a plane crash. The John shot on July 19, 1957, was the only test of the Air Force's AIR-2A Genie rocket with a nuclear warhead. [3] It was fired from an F-89J Scorpion fighter over Yucca Flats at the Nevada National Security Site.
On this day in 1957, the first underground nuclear test was carried out at the Nevada Test Site, a 1,375 square-mile research center located 65 miles away from Las Vegas.The 1,7 kiloton nuclear ...
The MET was the first bomb core to include uranium-233 (a rarely used fissile isotope that is the product of thorium-232 neutron absorption), along with plutonium; this was based on the plutonium/U-235 pit from the TX-7E, a prototype Mark 7 nuclear bomb design used in the 1951 Operation Buster-Jangle Easy test.
Trinity, part of Project Manhattan, was the first ever nuclear explosion. The nuclear weapons tests of the United States were performed from 1945 to 1992 as part of the nuclear arms race. The United States conducted around 1,054 nuclear tests by official count, including 216 atmospheric, underwater, and space tests.
[1] [2] Fallout was discovered after the Trinity test, the first ever atomic bomb test, in 1945. [2] Photographic film manufacturers later reported 'fogged' films ; this was traced to packaging materials sourced from Indiana crops, contaminated by Trinity and later tests at the Nevada Test Site , over 1,000 miles (1,600 km) away.

Operation Upshot–Knothole was a series of eleven nuclear test shots conducted in 1953 at the Nevada Test Site.It followed Operation Ivy and preceded Operation Castle.. Over 21,000 soldiers took part in the ground exercise Desert Rock V in conjunction with the Upshot-Knothole Grable shot. [1]
