The Fireball - Atomic Archive
The fireball, an extremely hot and highly luminous spherical mass of air and gaseous weapon residues, occurs within less than one millionth of one second of the weapon's detonation. Immediately after its formation, the fireball begins to grow in size, engulfing the surrounding air.
Nuclear Fireball Calculator – Nuclear Weapons Education Project
The nuclear fireball is tens of millions of degrees (i.e., as hot as the interior of the sun). Inside the fireball, the temperature and pressure cause a complete desintegration of molecules and atoms.
Rope trick effect - Wikipedia
Rope trick is the term given by American nuclear physicist John Malik to the curious lines and spikes which emanate from the fireball of nuclear explosions under certain conditions, just after detonation.
Nuclear weapon yield - Wikipedia
The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene which, if detonated, would produce the same energy discharge), either in kilotonnes ...
Formation of the fireball triggers the destructive effects of the nuclear explosion starts to form in less than a millionth of a second after explosion several tens of million of degrees: transformation of all matter into gas/plasma
NMHB 2020 [Revised] - Under Secretary of Defense for …
Nuclear Fireball. A typical nuclear weapon detonation can produce a huge number of X-rays, which heat the air around the detonation to extremely high temperatures, causing the heated air to expand and form a large fireball within a small fraction of a second. The size of the immediate fireball is a function of yield and the surrounding environment.
What exactly is the fireball caused by a nuclear bomb?
2023年8月5日 · A fireball marks the radius at which the plasma - ionised atoms and free electrons from the air, the ground (if detonated near the ground) the bomb casing and the nuclear explosive - become transparent to visible radiation.
The Effects of Nuclear Weapons - Glasstone and Dolan | Chapter II
After the lapse of 10 seconds, when the fireball of a 1-megaton nuclear weapon has attained its maximum size (5,700 feet across), the shock front is some 3 miles farther ahead. At 50 seconds after the explosion, when the fireball is no longer visible, …
Piecing Together a Nuclear Fireball | Science & Technology Review
In experiments simulating conditions in a nuclear fireball, equal amounts of iron and aluminum were injected into a plasma flow reactor. The patterns of emission spectra, like separate sets of fingerprints, reveal the presence of both aluminum oxide (red) and iron oxide (blue) in gas at 1,740 kelvins that cooled from plasma.
On the nuclear explosion fireball - IOPscience
2021年8月25日 · In this article, based on some assumptions, a simple exercise is performed to treat a nuclear explosion fireball as a mixture of radiation (photons) and particle gas, and study the radiation energy to gas energy ratio at later stages.
