    en.wikipedia.org/wiki/Effects_of_nuclear_explosions

    The effects of a nuclear explosion on its immediate vicinity are typically much more destructive and multifaceted than those caused by conventional explosives. In most cases, the energy released from a nuclear weapon detonated within the lower atmosphere can be approximately divided into four basic categories: [ 1 ]

    en.wikipedia.org/wiki/1945–1998

    The United States conducts several nuclear tests after the war. The Soviet Union and United Kingdom then gain nuclear weapons, increasing the number of explosions. [5] [6] The piece continues until it gets to Pakistan's first nuclear test in 1998. [7] The total number of weapons detonated is 2053. [8] The piece used sound and light to startle ...

  4. Atomic bombings of Hiroshima and Nagasaki - Wikipedia

    The atomic bomb explosion generated a windstorm several kilometers wide that carried ash, dust, and debris over the mountain ranges surrounding Nagasaki. Approximately 20 minutes after the bombing, a black rain with the consistency of mud or oil came down carrying radioactive material for one to two hours before turning clear. [227]

  5. Rope trick effect - Wikipedia

    en.wikipedia.org/wiki/Rope_trick_effect

    In the initial microseconds after the explosion, a fireball is formed around the bomb by the massive numbers of thermal x-rays released by the explosion process. These x-rays cannot travel very far in standard atmosphere before reacting with molecules in the air , so the result is a fireball that rapidly forms within about 10 metres (33 ft) in ...

  6. Nuclear explosion - Wikipedia

    en.wikipedia.org/wiki/Nuclear_explosion

    A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device.

  7. Taylor–von Neumann–Sedov blast wave - Wikipedia

    en.wikipedia.org/wiki/Taylor–von_Neumann...

    Consider a strong explosion (such as nuclear bombs) that releases a large amount of energy in a small volume during a short time interval. This will create a strong spherical shock wave propagating outwards from the explosion center. The self-similar solution tries to describe the flow when the shock wave has moved through a distance that is ...

  8. Leipzig L-IV experiment accident - Wikipedia

    en.wikipedia.org/wiki/Leipzig_L-IV_experiment...

    The Leipzig L-IV experiment accident was the first nuclear accident in history. It occurred on 23 June 1942 in a laboratory at the Physical Institute of the Leipzig University in Leipzig, Germany. There was a steam explosion and a reactor fire in the "uranium machine", a primitive form of research reactor. [1]

  9. Nuclear weapon - Wikipedia

    en.wikipedia.org/wiki/Nuclear_weapon

    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.
