This is known as a "radiatively driven" fireball. [citation needed] Inside the radiative fireball, the bomb itself is rapidly expanding due to the heat generated by the nuclear reactions. This moves outward at supersonic speeds, creating a hydrodynamic shock wave at its outer edge. After a brief period, this shock front reaches and then passes ...
It will occur only when the fireball is actually in the individual's field of vision and would be a relatively uncommon injury. Retinal burns may be sustained at considerable distances from the explosion. The height of burst and apparent size of the fireball, a function of yield and range will determine the degree and extent of retinal scarring.
A BLEVE–fireball at the Philadelphia Energy Solutions refinery, as rendered by the CSB. A boiling liquid expanding vapor explosion (BLEVE, / ˈ b l ɛ v iː / BLEV-ee) is an explosion caused by the rupture of a vessel containing a pressurized liquid that is or has reached a temperature sufficiently higher than its boiling point at atmospheric pressure.
The Southern Taurid meteor shower is set to peak Monday night into Tuesday with a chance for sky-gazers to spot fireballs. Here’s how to see the celestial show.

Nuclear weapons are usually detonated above the ground (not upon impact, because some of the energy would be dissipated by the ground motions), to maximize the effect of their spherically expanding fireball and blast wave. Immediately after the detonation, the fireball begins to rise into the air, acting on the same principle as a hot-air balloon.
Comparative fireball radii for a selection of nuclear weapons. [citation needed] Contrary to the image, which may depict the initial fireball radius, the maximum average fireball radius of Castle Bravo, a 15-megatonne yield surface burst, is 3.3 to 3.7 km (2.1 to 2.3 mi), [6] [7] and not the 1.42 km displayed in the image.
