The Australian Nuclear Science and Technology Organisation, or ANSTO, is a government agency based in Australia that focuses on nuclear science and technology. Established in 1987, it plays a crucial role in research, development, and the application of nuclear techniques for various fields, including medicine, industry, and environmental science. ANSTO operates the OPAL reactor, which is used for producing medical isotopes, conducting research, and testing materials. The organization also collaborates with international partners to advance nuclear science and promote safe and sustainable practices in the use of nuclear technology.
