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.

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.

Video of the formation of the fireball from a nuclear explosion. Within less than one millionth of one second from the detonation of the weapon, a fireball is formed. This fireball is an extremely hot and highly luminous spherical mass of air and gaseous weapon residues.

Intense thermal radiation at the hypocenter forms a nuclear fireball which, if the explosion is low enough in altitude, is often associated with a mushroom cloud. In a high-altitude burst where the density of the atmosphere is low, more energy is released as ionizing gamma radiation and X-rays than as an atmosphere-displacing shockwave.

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.

Materials vaporized by a nuclear explosion do not simply disappear without a trace in the resulting fireball. Resulting from the Sun’s nuclear processes, the erupting plasma from solar flares rapidly expands and cools similarly to what occurs in a nuclear fireball.

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.

piecing together a nuclear fireball. To study this complex fractionation process, researchers at Lawrence Livermore and collaborators from Stanford University and the University of Illinois at Urbana-Champaign (UIUC) have developed two different methods of physically simulating the plasma conditions in nuclear fireballs: pulsed laser ablati.

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.

In Research Area 3, the MSEE URA will investigate the nuclear fireball and the chemical agent defeat environment and associated neutralization strategies. This research is supported by the focus areas outlined below.
