Nuclear explosion
Nuclear Explosion
A Nuclear Explosion (pronunciation: /ˈnjuː.kliː.ər ɪkˈsploʊ.ʒən/) is a rapid release of energy from a high-speed nuclear reaction. The driving reaction may be nuclear fission, nuclear fusion or a multistage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device.
Etymology
The term "Nuclear Explosion" is derived from the Latin nucleus meaning "core", and the Latin explosio meaning "a driving out".
Related Terms
- Nuclear Fission: A nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy.
- Nuclear Fusion: A nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy.
- Radioactive Fallout: The residual radioactive material propelled into the upper atmosphere following a nuclear blast.
- Electromagnetic Pulse (EMP): A burst of electromagnetic radiation resulting from a nuclear explosion.
- Nuclear Weapon: An explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion.
