Runit Dome: A Lingering Legacy of Nuclear Testing

Robert Celestial, a former U.S. Army truck driver, found himself in Enewetak Atoll in the Marshall Islands in 1978, part of a nuclear clean-up operation. He and other soldiers were tasked with transporting contaminated soil and debris to a crater on Runit Island, unaware it was formed by a nuclear blast. They were told the debris was from World War II, but later discovered the site had experienced 43 nuclear detonations.

The Birth of "The Tomb"

Between 1946 and 1958, a staggering 67 nuclear tests were conducted across Enewetak and Bikini atolls, displacing over 300 Marshallese people. The 18-kiloton Cactus bomb, detonated on Runit Island, created a 10-meter-deep crater.

Deterioration and Rising Concerns

Today, the Runit Dome is deteriorating, with cracks visible on its surface. Groundwater flows beneath the structure, potentially carrying contaminated waste into the surrounding lagoon. Scientists express concerns that rising sea levels and intensifying storms could further degrade the dome, posing risks to nearby communities.

Health Crisis Among "Atomic Veterans"

Following his six-month tour, Celestial experienced severe health problems, including boils, brittle bones, osteoporosis, arthritis, and kidney/liver issues. While a direct link of all conditions to the clean-up is not definitively established, many veterans from Enewetak Atoll suffered similar ailments, including cancer.

It was only in 2023 that the U.S. government officially recognized these individuals as "atomic veterans," allowing them to access disability claims. Celestial reported that only a few hundred of the approximately 4,000 troops involved in the clean-up are still alive, with many having died from cancer.

Expert Warnings Versus Official Stance

Experts like Ivana Nikolic-Hughes of Columbia University have observed elevated radiation levels in soil samples outside the dome. She warns that the dome's integrity is jeopardized by climate change, with potentially devastating implications for the approximately 300 residents of Enewetak Atoll, who use the lagoon.

She also suspects the dome may contain debris and unexploded bomb material, including plutonium, which remains dangerous for over 24,000 years. Arjun Makhijani, a nuclear engineer, noted that no concrete structure can endure such a lifespan.

The U.S. Department of Energy states that the cracks are consistent with aging concrete and argues that any contamination from the dome is minor compared to the radioactive material already present in the lagoon from past tests. However, critics question the necessity of building the dome if the lagoon was already heavily contaminated.

The Marshallese Predicament

The Marshallese government lacks the technical and financial resources to address the dome's issues. The 1986 Compact of Free Association, which granted the Marshall Islands independence, also settled "all claims, past, present and future" related to the U.S. nuclear testing program, placing the responsibility for the dome largely on the Marshallese government.

Marshallese officials assert they did not have complete information when the agreement was signed. Former Marshallese health secretary Jack Niedenthal characterized the dome as a symbol of America's past errors.
