![]() ![]() The geography of Nagasaki prevents destruction on the same scale as Hiroshima, yet nearly half the city is obliterated. The bomb creates a blast radius one mile wide (1609.34m). Bombardier Kermit Beahan releases the Fat Man atomic bomb.ġ202 (11:02am in Nagasaki) Fat Man explodes 1,650 feet (502.92m) above the city. Haze makes it too difficult to locate the drop point.ġ132 Major Charles Sweeney, Bockscar’s pilot, makes the decision to turn for the secondary target, Nagasaki, 95 miles south of Kokura.ġ158 Upon arrival over Nagasaki, cloud cover allows for only one drop point, several miles from the intended target. Fred Ashworth arms Fat Man atomic bomb.ġ044 Bockscar arrives at Kokura. Two weather-spotting aircraft, the Enola Gay and Laggin’ Dragon are already airborne.Ġ400 Cmdr.

See damage from another blast or learn more about fallout and other effects of a nuclear explosion.NATIONAL ARCHIVES Nagasaki August 9, 1945 Its represented by a bomber plane, so it works the same way as an air unit and can be. With a bomb a thousand times more powerful than the Hiroshima bomb, the radius of damage will be ten times greater. The zones of destruction described on this page are broad generalizations and do not take into account factors such as weather and geography of the target. An Atomic Bomb is the first weapon of mass destruction in the game. ![]() NOTE: This information has been drawn mainly from "The Effects of Nuclear War" (Washington: Office of Technology Assessment, Congress of the United States, 1979). The remaining seventy-five percent are unhurt. Many others have been injured from thermal radiation - the heat generated by the blast. Twenty-five percent of the population between the 2 and 1 psi rings have been injured, mainly by flying glass and debris. Commercial buildings have sustained minimal damage. Five percent of the population between the 5 and 2 psi rings are dead. A substantial amount of debris clutters the entire area. The contents of these buildings' upper floors, including the people who were working there, are scattered on the street. Since the conclusion of the weapons testing in the 1980s, radionuclides in the atmosphere have largely decayed away. It is called fallout and it typically contains hundreds of different radionuclides. Nearly everything was heavily damaged up to a radius of 3 miles from the blast, and beyond this distance damage, although comparatively light, extended for. ![]() This mixture is sent up into the air and then falls back to Earth. The windows of office buildings have been blown away, as have some of their walls. After a nuclear explosion, debris and soil can mix with radionuclides. fission When a neutron strikes the nucleus of an atom of the isotopes uranium-235 or plutonium-239, it causes that nucleus to split into two fragments, each of which is a nucleus with about half the protons and neutrons of the original nucleus. Background Pacific War Situation of the Pacific War on 1 August 1945. Forty percent are injured.Īny single-family residences that have not been completely destroyed are heavily damaged. Fifty percent of the population between the 12 and 5 psi rings are dead. Single-family residences within this this area have been completely blown away - only their foundations remain. The bare, structural skeletons of more and more buildings rise above the debris as you approach the 5 psi ring. The walls of typical multi-story buildings, including apartment buildings, have been completely blown out. Virtually everything is destroyed between the 12 and 5 psi rings. Ninety-eight percent of the population in this area are dead. At 1.7 miles, only some of the strongest buildings - those made of reinforced, poured concrete - are still standing. Nothing recognizable remains within about 3,200 feet (0.6 miles) from the center, except, perhaps, the remains of some buildings' foundations. The rim of this crater is 1,000 feet wide and is composed of highly radioactive soil and debris. A 1 megaton hydrogen bomb, hypothetically detonated on the earth's surface, has about 80 times the blast power of that 1945 explosion.Īt the center lies a crater 200 feet deep and 1000 feet in diameter. The fission bomb detonated over Hiroshima had an explosive blast equivalent to 12,500 tons of TNT. Nearly everything was heavily damaged up to a radius of 3 miles from the blast, and beyond this distance damage, although comparatively light, extended for several more miles. ![]()
