A Nuclear weapon is a type of explosive weapon that derives its destructive force from Nuclear reactions of fission or a combination of fission and fusion. As a result, even a nuclear weapon with a small yield Is significantly more powerful than the largest conventional explosives, and a single weapon is capable of destroying an entire city. There are two basic types of Nuclear weapons. The first are weapons which produce their explosive which produce their explosive energy through nuclear fission reactions alone. These are Known celloquality as atomic bombs. A bombs, or fission bombs. The second basic type of Nuclear weapon produces a large amount of its energy through nuclear fusion reactions, and can be over a thousand times more powerful than fission bombs as fusion reaction. These are as hydrogen bombs, H-bombs, Thermo-nuclear-bombs, or fusion bombs. With the advancement of scientific reasearch in the world, several countries have acquired the technology to produce Nuclear Arms. There is also a risk of accidental exposure to harmful radiation from the several nuclear reactors that are used to generate power. Theft of nuclear materials can enable the creation of crude bombs commonly known as ‘dirty bombs’ which can be used by elements of terrorist groups. antisocial elements of terrorist groups.
