  2. 1945–1998 - Wikipedia

    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 ...

  3. Effects of nuclear explosions - Wikipedia

    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 ]

  4. 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 ...

  5. Demon core - Wikipedia

    en.wikipedia.org/wiki/Demon_core

    The demon core (like the core used in the bombing of Nagasaki) was, when assembled, a solid 6.2-kilogram (14 lb) sphere measuring 8.9 centimeters (3.5 in) in diameter.. It consisted of three parts made of plutonium-gallium: two hemispheres and an anti-jet ring, designed to keep neutron flux from "jetting" out of the joined surface between the hemispheres during implosi

  6. Nuclear close calls - Wikipedia

    en.wikipedia.org/wiki/Nuclear_close_calls

    A nuclear close call is an incident that might have led to at least one unintended nuclear detonation or explosion, but did not. These incidents typically involve a perceived imminent threat to a nuclear-armed country which could lead to retaliatory strikes against the perceived aggressor.

  7. Atomic bombings of Hiroshima and Nagasaki - Wikipedia

    en.wikipedia.org/wiki/Atomic_bombings_of...

    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]

  8. Operation Teapot - Wikipedia

    en.wikipedia.org/wiki/Operation_Teapot

    The MET was the first bomb core to include uranium-233 (a rarely used fissile isotope that is the product of thorium-232 neutron absorption), along with plutonium; this was based on the plutonium/U-235 pit from the TX-7E, a prototype Mark 7 nuclear bomb design used in the 1951 Operation Buster-Jangle Easy test.

  9. Operation Plumbbob - Wikipedia

    en.wikipedia.org/wiki/Operation_Plumbbob

    The operation consisted of 29 explosions, of which only two did not produce any nuclear yield.Twenty-one laboratories and government agencies were involved. While most Operation Plumbbob tests contributed to the development of warheads for intercontinental and intermediate range missiles, they also tested air defense and anti-submarine warheads with smaller yields.
