Nuclear Bomb Explosion
At present nuclear detonations are the most devastating of the weapons of mass destruction. Depending upon the environment in which the nuclear device is detonated, blast effects are manifested as ground shock, water shock and large amounts of dust and radioactive fallout.
The energy of a nuclear explosion is transferred to the surrounding medium in three distinct forms: blast; thermal radiation; and nuclear radiation.
Because of the tremendous amounts of energy liberated per unit mass in a nuclear detonation, temperatures of several tens of millions degrees centigrade develop in the immediate area of the detonation. This is in marked contrast to the few thousand degrees of a conventional explosion. At these very high temperatures the non-fissioned parts of the nuclear weapon are vaporized. The atoms do-not release the energy as kinetic energy but release it in the form of large amounts of electromagnetic radiation.
