Energy from a nuclear explosive is initially released in several forms of penetrating radiation. When there is a surrounding material such as air, rock, or water, this radiation interacts with and rapidly heats it to an equilibrium temperature. Causing vaporization of surrounding material resulting in its rapid expansion. Kinetic energy created by this expansion contributes to the formation of a shockwave. When a nuclear detonation occurs in air near sea level, much of the released energy interacts with the atmosphere and creates a shockwave which expands spherically from the hypocenter. Intense thermal radiation at the hypocenter forms a fireball and if the burst is low enough, its often associated mushroom cloud. In a burst at high altitudes, where the air density is low, more energy is released as ionizing gamma radiation and x-rays than an atmosphere displacing shockwave. | Energy from a nuclear explosive is initially released in several forms of penetrating radiation.

The Cold War on [[Earth]] saw increased tensions and fear of Nuclear War sparking between the [[United States of America]] and the [[Soviet Union]]. The two countries and their respective spheres of influence found themselves on constant alert of nuclear launch and nuclear war. | The Cold War on [[Earth]] saw increased tensions and fear of Nuclear War sparking between the [[United States of America]] and the [[Soviet Union]].

During this period the humanity tested the most powerfull device, one of the most know the Tsar Bomba. | ||
