This is an accepted article with a DOI pre-assigned that is not yet published.The traumatic impacts of uranium mining on Diné (Navajo) communities in Arizona, New Mexico, and Utah in the late 20th century – from high cancer rates among mineworkers and their families to the radioactive contamination of local resources – have become well-known cases of radioactive injustice.  Much less recognized is how these experiences were significant on a global stage.  This paper explores how Diné uranium experiences and activism became entangled in two other particularly fraught global arenas of nuclear and settler colonial politics in the late 1970s and early 1980s:  activism by various Aboriginal communities in northern Australia to protect their rights, lands, and health as uranium mining operations expanded; and the struggles of Namibians as they opposed both the conditions of uranium mining and political control by apartheid South Africa.  In these years, Diné and other Native American activists, along with non-Native allies, utilized a variety of transnational platforms – in multiple settings in Australia, the U.S., and western Europe – to forge solidarities with Aboriginal and Namibian actors, offer tragic lessons learned from Diné communities’ long-running problems with uranium, and highlight the radioactive vulnerabilities and concerns they commonly shared as Indigenous peoples subordinated within structures of settler colonial and multinational corporate power.
