"History of 10,000 ton gadget":
Critical explanation and analysis

"Destruction of a military target by a nuclear fission weapon is comprehended mainly by the effects of a powerful blast wave in air but the more distant military consequences of a nuclear explosion can be significantly augmented by the thermal (heat) radiations emitted by the fireball that emerges from the isothermal sphere. Furthermore, accurate anticipation of the thermal characteristics and physical behavior of an isothermal sphere as it endures and rises above a nuclear explosion can be useful as a basis to predict the military and environmental effects of radioactive fallout since most of the dangerous fission byproducts of an atomic bomb detonation are concentrated in the isothermal sphere."
