Nuclear Testing Legacy
Cracks in a dome built over a crater left by a 1958 nuclear blast in the Marshall Islands may now be leaking radioactive contamination around Enewetak Atoll.
The Runit dome was built by the United States in 1977, designed to also contain radioactive debris from other nuclear tests in the Pacific between 1946 and 1958. But the new cracks and rising sea levels threaten to inundate the atomic dump, further contaminating the Pacific atoll.
Some of the Enewetak residents evacuated before the blast were finally allowed to return in 1980 after the dome was completed and the Marshall Islands government accepted the U.S. cleanup efforts as final.
