Enewetak Atoll

Enewetak is a large atoll in the far northwest of the Marshall Islands that served as a major United States nuclear testing ground in the 1940s and 1950s, including the first hydrogen-bomb detonation. Contaminated debris from the cleanup was later sealed under a concrete dome on Runit Island, a structure that has come to symbolise the unresolved dangers of the atomic era. Parts of the atoll have been resettled, but its history is dominated by the tests.
