Nuclear terrorism refers to the use or threat of nuclear weapons or materials by non-state actors, such as terrorist groups. This can involve the detonation of a nuclear bomb or the dispersal of radioactive materials, which could cause widespread destruction and panic. The potential for such acts raises significant security concerns globally. Preventing nuclear terrorism involves international cooperation and strict regulations on the handling of nuclear materials. Organizations like the International Atomic Energy Agency (IAEA) work to ensure that nuclear materials are secured and monitored to prevent them from falling into the hands of terrorists.
