Uranium is a radioactive element which undergoes alpha decay, which means that it will give off helium nuclei. It can also decay by spontaneous fission. This fission involves the release of neutrons which destabilize the nuclei of different uranium atoms, which will in turn give off more neutrons through fission. If the amount of radioactive material is too small, then most of the neutrons will simply leave the substance, but if it is greater than a critical mass, then more of them will interact with other Uranium nuclei, and the amount of free neutrons will increase exponentially, quickly releasing a large amount of energy. This only works for certain elements, such as Uranium 235 and Plutonium 239, and since most of the Uranium around is Uranium 238, it is necessary to have a high enough concentration of Uranium 235 by removing the Uranium 238 from it.

Other than in a nuclear weapon, uranium could be used as a component of a "dirty bomb". This is an ordinary explosive bomb with uranium metal add. Because the uranium is radioactive, the bomb will spread radioactivity over a wide area increasing casualties. However, it is believed that the real effect would be the panic caused by fear of radiation, which could be worse than the actual harm done by the radioactivity.

Uranium in an enriched state makes fissile material for a NUCLEAR BOMB.
Uranium in a depleted metallic state makes armor-piercing bullets as used by the US Army's M1A1 Abrams main battle tank.

It's radioactive. Leave it around and people get poisioned from the radiation. Enrich it and make an atom bomb out of it.

depleted uranium is put into shells (big bullets) to penetrate armor
i hope youre not a terrorist
