The Fat Man mushroom cloud resulting from the nuclear explosion over Nagasaki rises into the air from the hypocenter.. Substantial debate exists over the ethical, legal, and military aspects of the atomic bombings of Hiroshima and Nagasaki on 6 August and 9 August 1945 respectively at the close of the Pacific War theater of World War II (1939–45).
Fallout may get entrained with the products of a pyrocumulus cloud and when combined with precipitation falls as black rain (rain darkened by soot and other particulates), which occurred within 30–40 minutes of the atomic bombings of Hiroshima and Nagasaki. [1] This radioactive dust, usually consisting of fission products mixed with ...
Unlike the other target cities, Nagasaki had not been placed off limits to bombers by the Joint Chiefs of Staff's 3 July directive, [120] [189] and was bombed on a small scale five times. During one of these raids on 1 August, a number of conventional high-explosive bombs were dropped on the city.
For Congress, compensating them remains politically radioactive: ... a carefully crafted bid to recast nuclear technology as peaceful after the atrocious 1945 Hiroshima and Nagasaki bombings ...

Hans M. Kristensen, director of the Nuclear Information Project at the Federation of American Scientists, stated that "if you start detonating nuclear weapons in the [battlefield] you potentially get radioactive fallout that you can't control — it could rain over your own troops as well, so it might not be an advantage to do that in the field."
The largest and therefore most radioactive particles are deposited by fallout in the first few hours after the blast. Smaller particles are carried to higher altitudes and descend more slowly, reaching ground in a less radioactive state as the isotopes with the shortest half-lives decay the fastest. The smallest particles can reach the ...
Human Shadow Etched in Stone (人影の石, hitokage no ishi) [2] is an exhibition at the Hiroshima Peace Memorial Museum.It is thought to be the shadow of a person who was sitting at the entrance of Hiroshima Branch of Sumitomo Bank when the atomic bomb was dropped over Hiroshima.
