|Q:||Ask a Question about Atom bomb|
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.
