The International Atomic Energy Agency (IAEA): A prominent Vienna, Austria-based intergovernmental organisation within the United Nations system, the IAEA is dedicated to promoting the peaceful use of nuclear energy and preventing its diversion for military purposes. Its main areas of focus include implementing safeguards, fostering nuclear safety and security standards, and providing technical cooperation for peaceful applications in areas like medicine, agriculture, and energy. Recognised for its crucial role in global non-proliferation efforts, the IAEA was awarded the Nobel Peace Prize in 2005.
