It was the first of seven nuclear detonations that Britain would conduct at Maralinga over the next two years, part of a testing program that would also scatter plutonium and uranium across thousands of square kilometers of Aboriginal land through so-called "minor trials" that continued until 1963. The site lay within the Woomera Prohibited Area, about 800 kilometers northwest of Adelaide. The people whose country it was -- the Maralinga Tjarutja, a southern Pitjantjatjara people who had lived in the Great Victoria Desert for millennia -- were not consulted. They were simply moved.

British and Australian servicemen were deliberately positioned to witness the blasts, some ordered to advance toward ground zero shortly after detonation to study the effects of radiation exposure on troops. They were given no meaningful protective equipment. Participants were bo...

Between 1953 and 1963, hundreds of so-called "minor trials" were conducted at Maralinga, testing weapons components, detonation mechanisms, and dispersal patterns without full nuclear explosions. These trials -- bearing c...

The first, called Operation Brumby, was carried out by the British in the 1960s and widely criticized as inadequate.
