Project Mogul (sometimes referred to as Operation Mogul) was a top secret project by the US Army Air Forces involving microphones flown on high-altitude balloons, whose primary purpose was long-distance detection of sound waves generated by Soviet atomic bomb tests. The project was carried out from 1947 until early 1949.
Inside the radiative fireball, the bomb itself is rapidly expanding due to the heat generated by the nuclear reactions. This moves outward at supersonic speeds, creating a hydrodynamic shock wave at its outer edge. After a brief period, this shock front reaches and then passes the initial radiative fireball.
The Tumbler-Snapper detonations included some particularly fallout-heavy weapons. Of particular note is shot George, which contaminated more citizens than any other nuclear test in the United States. George alone accounted for some 7 percent of all population exposure to radiation during the 1,032 nuclear tests performed by the United States ...

Despite the lethal radiation and blast zone extending well past her position at Hiroshima, [55] Takakura survived the effects of a 16 kt atomic bomb at a distance of 300 metres (980 ft) from the hypocenter, with only minor injuries, due mainly to her position in the lobby of the Bank of Japan, a reinforced concrete building, at the time.
In a chilling simulation released in North Korea, a nuclear bomb strikes the United States, creating a massive mushroom cloud.
A nuclear weapon [a] is an explosive device that derives its destructive force from nuclear reactions, either fission (fission or atomic bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter.
