Nuclear Explosion Is Caused by Radio-Nuclear Isotopes Bombardment Causes Multiple Disasters

A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either nuclear fission (fission or atomic bomb) or a combination of fission and nuclear fusion reactions (thermonuclear weapon; H-bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. Nuclear weapons have had yields between 10 tons (the W54) and 50 megatons for the Tsar Bomba. Yields in the low kilotons can devastate cities. A thermonuclear weapon weighing as little as 600 pounds (270 kg) can release energy equal to more than 1.2 megatons of TNT (5.0 PJ). Apart from the blast, effects of nuclear weapons include extreme heat and ionizing radiation, firestorms, radioactive nuclear fallout, an electromagnetic pulse, and a radar blackout. An atomic bomb (A-bomb) is a type of nuclear weapon that uses nuclear fission (splitting atoms) to create an explosion, typically in the kiloton range, like those used in WWII [World War II]. A nuclear bomb is a broader term covering both A-bombs and more powerful hydrogen bombs (thermonuclear), which use fusion to produce massive megaton-range yields.
