Marshall islands, pollution from tests

A Pacific Island is sitting atop a nuclear time bomb that could pollute

the oceans for centuries. Scientists have discovered that a concrete
structure built to contain radioactive waste from Cold War-era testing is
showing signs of deterioration. The site, known as Runit Dome, sits on
Runit Island in the Enewetak atoll in the Marshall Islands. Although Runit
itself is uninhabitable, the atoll is home to around 300.
