In which year did the IAEA become established?

The International Atomic Energy Agency (IAEA) was established in 1957, which is the correct answer. The creation of the IAEA came in the context of the need for international cooperation in the field of nuclear energy and safety, especially after World War II and the advent of nuclear weapons. The agency was founded to promote the peaceful use of nuclear energy and to inhibit its use for military purposes, signaling a critical step toward global nuclear governance.

This establishment year is significant because it reflects the growing recognition of nuclear energy's potential benefits and the associated risks that required international oversight. It was during this period that nations began to understand the dual nature of nuclear technology, leading to the need for a dedicated organization that could facilitate cooperation among member states while ensuring safety and security standards were upheld.
