May 21, 2021 Almost 60 years after British nuclear tests ended, radioactive particles containing plutonium and uranium still contaminate the landscape around Maralinga in outback South Australia.
These “hot particles” are not as stable as we once assumed. Our research shows they are likely releasing tiny chunks of plutonium and uranium which can be easily transported in dust and water, inhaled by humans and wildlife and taken up by plants.

Australian scientists pave the way to the first International standards needed to safeguard against contamination from nuclear testing
More than 100kg of highly toxic uranium (U) and plutonium (Pu) was dispersed in the form of tiny ‘hot’ radioactive particles after the British detonated nine atomic bombs in remote areas of South Australia, including Maralinga.
Scientists have new evidence to show these radioactive particles persist in soils to this day, more than 60 years after the detonations. Previously, we had limited understanding of how Pu was released from these “hot” particles into the environment for uptake by wildlife around Maralinga.
