Our History

In April 15, 1953, Australia entered the nuclear science arena, when the Atomic Energy Act came into effect. The Australian Atomic Energy Commission (AAEC) followed and in 1987 the AAEC evolved into the Australian Nuclear Science and Technology Organisation (ANSTO) as it’s known today.
