Atom bomb

 Q:   Ask a Question about Atom bomb       
Atom bomb The atom bomb is such a powerful weapon that it has only been used in anger twice, near the end of World War II, and even testing has now been abandoned. The technology to produce atomic weapons is very complex and only a few countries have managed to make them.

How do nuclear weapons work?

Atom bombs are a form of uncontrolled nuclear fission. When a large enough mass of uranium is put together, a fission reaction starts. The flood of neutrons emitted becomes so enormous that a vast amount of energy is released in a very short time, producing an atomic blast.

Hydrogen bombs have an atomic bomb at their heart, but this core is surrounded by a layer of light material. Using the power released from the fission of the uranium or plutonium core, this layer of material causes a fusion reaction like the one in the core of the Sun. This nuclear fusion releases more heat energy than a fission explosion, as well as huge amounts of radioactivity.
