Runit Island

Enewetak Atoll is a part of the Marshall Islands in the Pacific Ocean. The island of note here is Runit Island. This is because the U.S. conducted nuclear testing on the atoll for years – until the late 1970s, when some residents were allowed to return. Unfortunately, a massive cleanup operation was needed which the US undertook in 1977, taking 111,000 cubic yards of contaminated earth and other materials from nearby islands and burying it in a blast crater at the end of Runit Island.
