Nuclear explosions are something that is bad for people and for all our planet. On this photos we can see what explosions can do to people and to our lovely nature.
A nuclear explosion is a man-made explosion that occurs as a result of the rapid release of energy from an intentionally generated 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.
Atmospheric nuclear explosions are associated with mushroom clouds, although mushroom clouds can occur with large chemical explosions, and it is possible to have an air-burst nuclear explosion without these clouds. Nuclear explosions produce radiation and radioactive debris.
