The Australian Nuclear Science and Technology Organisation (ANSTO) is a government agency responsible for nuclear science and technology in Australia. Established in 1987, it conducts research and development in various fields, including nuclear medicine, environmental science, and materials engineering. ANSTO operates the Opal reactor, which produces radioisotopes for medical use and supports scientific research. ANSTO also collaborates with international organizations and institutions to advance nuclear science. It plays a crucial role in training scientists and engineers, promoting the safe use of nuclear technology, and contributing to Australia's energy and health sectors.
