Runit Island (/ˈruːnɪt/) is one of forty islands of the Enewetak Atoll of the Marshall Islands in the Pacific Ocean. The island is the site of a radioactive waste repository left by the United States after it conducted a series of nuclear tests on Enewetak Atoll between 1946 and 1958. There are ongoing concerns around deterioration of the waste site and a potential radioactive spill.
