The impact of the bombs

An atomic bomb causes massive destruction through intense heat, pressure, radiation and radioactive fallout. At the hypocentre (centre of the blast), the heat is so intense, it vaporises people and buildings.

Atomic bombs are nuclear weapons that use the energetic output of nuclear fission to produce massive explosions. Only two nuclear weapons have been used in the course of warfare, both by the U.S. near the end of World War II.

Atomic bomb is A thermonuclear weapon weighing little more than 2,400 pounds (1,100 kg) can release energy equal to more than 1.2 million tons of TNT (5.0 PJ). A nuclear device no larger than traditional bombs can devastate an entire city by blast, fire, and radiation.
