After the detonation of a weapon at or above the fallout-free altitude (an air burst), fission products, un-fissioned nuclear material, and weapon residues vaporized by the heat of the fireball condense into a suspension of particles 10 nm to 20 μm in diameter.
The medical effects of the atomic bomb upon humans can be put into the four categories below, with the effects of larger thermonuclear weapons producing blast and thermal effects so large that there would be a negligible number of survivors close enough to the center of the blast who would experience prompt/acute radiation effects, which were observed after the 16 kiloton yield Hiroshima bomb ...
To find the optimum height of burst for any weapon yield, the cube root of the yield in kilotons is multiplied by the ideal H.O.B for a 1 kt blast, e.g. the optimum height of burst for a 500 kt weapon is ~1745 m. [4] An estimate of the size of the damage caused by the 16 kt and 21 kt atomic bombings of Hiroshima and Nagasaki.
The bombings killed between 150,000 and 246,000 people, most of whom were civilians, and remain the only use of nuclear weapons in an armed conflict. Japan surrendered to the Allies on 15 August, six days after the bombing of Nagasaki and the Soviet Union's declaration of war against Japan and invasion of Japanese-occupied Manchuria.
The 1958 Mars Bluff B-47 nuclear weapon loss incident was the inadvertent release of a nuclear weapon from a United States Air Force B-47 bomber over Mars Bluff, South Carolina. The bomb, which did not have its fissile nuclear core installed at the time of the accident, impacted with the ground, and its conventional high explosives detonated.

A B83 casing. The B83 is a variable-yield thermonuclear gravity bomb developed by the United States in the late 1970s that entered service in 1983. With a maximum yield of 1.2 megatonnes of TNT (5.0 PJ), it has been the most powerful nuclear weapon in the United States nuclear arsenal since October 25, 2011 after retirement of the B53. [1]
