The toxic legacy of the nuclear era is resurfacing as cracks have been detected in the Runit Dome — raising long-term concerns for the people of the Marshall Islands.
The Runit Dome, often called “The Tomb,” is a massive concrete structure in the Marshall Islands built to contain radioactive waste from U.S. nuclear testing during the Cold War. Experts have recently identified cracks in the dome, which holds more than 120,000 tons of radioactive debris and contaminated soil, including plutonium-239 — a substance that remains hazardous for over 24,000 years.
One of the most critical issues is that the dome was never built with a protective lining beneath it. As a result, groundwater can already seep through the porous coral foundation underneath. Rising sea levels, storm surges, and tidal flooding may further accelerate the spread of radioactive materials into the surrounding environment in the future.
Scientists warn that while current leakage levels may not yet be severe, the long-term risks are deeply alarming. Runit Island sits only around 2 meters above sea level and could face worsening threats as climate change drives ocean levels higher.
Experts and human rights advocates are therefore calling on the United States to take greater responsibility for managing this nuclear legacy and ensuring long-term protection for the people of the Marshall Islands.
