The concrete cap of a tomb encasing radioactive fallout now has cracks, and what’s beneath can rise from the dead. The US military, in 1958, conducted a nuclear test on Runit Island in the Marshall Islands with an 18-kiloton bomb called Cactus. The resulting blast left behind an almost 33-foot (10-metre) deep crater, which later became a dumping ground for the debris from a myriad of nuclear tests from the 1940s to 50s. In 1977, the Runit Dome was created to contain that radioactive waste. But the dome’s deterioration could contaminate the ocean and displace hundreds of people.
The Runit Dome contains more than 120,000 tons of contaminated material from nuclear testing, including lethal quantities of plutonium. The isotope plutonium-239 is a “radioactive element used in nuclear weapons that remains dangerous for more than 24,000 years,” said the Australian Broadcasting Corporation (ABC).
Merely coming into contact with the radioactive element can kill you. Concrete, unfortunately, does not endure that long. “There are already cracks in it in less than 50 years,” Arjun Makhijani, a nuclear engineer and president of the Institute for Energy and Environmental Research, said to the ABC.
The ocean has been “steadily encroaching on the dome over the years,” and “residents fear nuclear contamination if the site were to collapse,” said The Cool Down. The problem is expected to worsen over time without climate change mitigation. “Legacies of nuclear testing and military land requisitions by a foreign power have displaced hundreds of Marshallese for generations,” Paula Gaviria Betancur, the UN Special Rapporteur, said in 2024, and the “adverse effects of climate change threaten to displace thousands more.” |
