Difference between A bomb and H bomb : An Atom bomb releases energy generated by the breaking apart of plutonium or uranium nuclei. A hydrogen bomb release energy created when atoms of an isotope of hydrogen are brought together. It takes an atom bomb, to create the conditions to operate a hydrogen bomb so a fission device is installed to trigger a fusion, or thermonuclear, explosion, duplicating conditions for a fraction of a second similar to those that go on at the center of our sun. The difference between a hydrogen bomb and a regular uranium or plutonium bomb is that a hydrogen bomb uses fusion instead of fission to generate the main explosion. In a fission reaction, unstable isotopes of the heavy elements uranium and plutonium are split into smaller atoms, releasing a large amount of energy proportional to the amount of material used. In a fusion reaction, two atoms of the lightest element, hydrogen, fuse to create one atom of helium, the next-lightest element — and release much more energy. Effects of nuclear weapons : Blast : The enormous release of energy in a nuclear explosion heats the air very quickly. The hot air expands rapidly, creating a shock wave (or blast) that travels out from the site of the explosion. This blast accounts for half the energy released by the explosion. It can flatten buildings near the explosion site and cause damage for miles around. The force of the explosion can also produce a large crater in the ground. Heat. A nuclear explosion creates a fireball with temperatures of millions of degrees. The temperatures are high enough to instantly destroy almost anything near the site of the explosion. Heat accounts for about a third of the energy released in the explosion. The heat from the fireball can set off raging fires over a wide area. Meanwhile, dust and dirt are sucked into the fireball. Because hot air rises, the dust and dirt rise with the fireball, creating a huge, mushroom-shaped cloud. Radiation. Along with the blast and heat, large amounts of harmful radiation are released in a nuclear explosion. About half of this radiation is called prompt radiation and is mostly in the form of neutrons and gamma rays (high-energy rays that, like X rays, are very penetrating). The radiation can kill people and animals near the site of the explosion. Even several miles away, people can become sick from exposure to radiation. And
