The cover to the Project 4.1 Final Report, "Study of Response of Human Beings Accidentally Exposed to Significant Fallout Radiation" Project 4.1 was the designation for a medical study and experimentation conducted by the United States of those residents of the Marshall Islands exposed to radioactive fallout from the 1 March 1954 Castle Bravo nuclear test at Bikini Atoll, which had an ...
The limiting value of the albedo for high-Z materials is reached when the thickness is 5–10 g/cm 2, or 0.5–1.0 free paths. Thus, a hohlraum made of uranium much thicker than a free path of uranium would be needlessly heavy and costly. At the same time, the angular anisotropy increases as the atomic number of the scatterer material is reduced.
Mushroom cloud from China's first nuclear test, Project 596. China tested its first nuclear weapon device ("596") in 1964 at the Lop Nur test site. The weapon was developed as a deterrent against both the United States and the Soviet Union. Two years later, China had a fission bomb capable of being put onto a nuclear missile.
The Mk-21 design project began on 26 March 1954 (just three weeks after Bravo), with production of 275 weapons beginning in late 1955. Romeo , relying on natural lithium, was rapidly turned into the Mk-17 bomb , the first deployable US thermonuclear weapon , [ 10 ] and was available to strategic forces as an Emergency Capability weapon by mid-1954.
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.
The device was the most powerful nuclear weapon ever detonated by the United States. Bravo had just under one third the energy of the Soviet Tsar Bomba, the largest nuclear device ever tested. However, while the Soviets intended to create such a large weapon, Castle Bravo's yield was much higher than anticipated.
