Project Mogul (sometimes referred to as Operation Mogul) was a top secret project by the US Army Air Forces involving microphones flown on high-altitude balloons, whose primary purpose was long-distance detection of sound waves generated by Soviet atomic bomb tests. The project was carried out from 1947 until early 1949.
The prime example of a "major nuclear accident" is one in which a reactor core is damaged and significant amounts of radioactive isotopes are released, such as in the Chernobyl disaster in 1986 and Fukushima nuclear disaster in 2011.
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]
Trinity and Beyond: The Atomic Bomb Movie is a 1995 American documentary film directed by Peter Kuran and narrated by William Shatner. [3]Using restored archive footage, the film traces the development of nuclear weapons and their testing, from America's Trinity test of 1945 (hence the title) to the first Chinese atomic bomb test in 1964.
The device used in the blast was a 16 kt Mark 5 Nuclear Bomb - a low yield fission weapon, detonated 90 meters / 300 feet above the ground. [2] The live TV coverage was recorded on a kinescope, so it is a rare record of the sound an actual atomic bomb makes. [3] One of the automobiles after the test.
Enola Gay: The Men, the Mission, the Atomic Bomb (NBC, 1980) – made-for-television docudrama about the Army Air Force B-29 unit that dropped the first atomic bomb to be used in combat on Hiroshima, Japan at the end of World War II. Fail-Safe (1964) – a film based on the novel of the same name about an American bomber crew and nuclear tensions
In a chilling simulation released in North Korea, a nuclear bomb strikes the United States, creating a massive mushroom cloud.
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.
