Maralinga
Referred to as "Section 400" this secret operation exposed surrounding Indigenous communities to radiation by contaminating the soil and water sources. Walter MacDougal, who threatened to go to the press, was tasked with searching 100, 000km by car to alert local Aboriginals, of the dangers, in some cases forcing them to leave their home. Despite this over one thousand Indigenous people were exposed to radiation, alternatively known as black mist by the locals.
