Improvised nuclear device

Improvised nuclear devices or (INDs) are theoretical illicit nuclear weapons bought, stolen, or otherwise originating from a nuclear state, or a weapon fabricated by a terrorist group from illegally obtained fissile nuclear weapons material that produces a nuclear explosion. An IND could be bought, or it could be built from the components of a stolen weapon or from scratch using nuclear material (plutonium, uranium, or highly enriched uranium). A successful detonation would result in catastrophic loss of life, destruction of infrastructure, and nuclear contamination of a very large area.
