85,000 cubic meters of radioactive waste is housed in a huge dome-shaped structure built on an island over the Pacific Ocean

On Runit Island in the Pacific Ocean, there are dome-shaped structures that look like tombs. It is said that 85,000 cubic meters of plutonium-239 is contained in it, not old remains.

Bikini Atoll and Enewetak Atoll are atolls located in the Pacific Ocean, southeast of Japan. It now belongs to the Republic of the Marshall Islands, but was a trusteeship territory of the United States from 1947 to 1982 after the end of World War II.

During the Cold War after World War II, the US military forced the inhabitants of the Marshall Islands to relocate

and conduct a total of 67 nuclear tests. During a series of nuclear tests, the crew of Daigo Fukuryu Maru , who was engaged in tuna fishing outside the dangerous waters set by the United States, was exposed. Aikichi Kuboyama, who was the radio chief of the ship, died six months after the bombing.

Of the 40 islands on the Enewetak Atoll in the Marshall Islands, which was the center of the nuclear test, four were wiped out by the test. And now, on Enewetak Atoll Runit Island, a huge dome-shaped structure remains.

Plutonium-239 , which was used as a nuclear warhead and is described as 'one of the most toxic substances on the earth' due to its high specific activity , is deposited in the dome as much as 85,000 cubic meters. I will. The top of the dome is 45 centimeters thick concrete, but the soil is permeable, with seawater coming in and out as the sea level rises.

In 2013, the United States Department of Energy reported that the dome was leaking radioactive material, banning the export of copra and fish from Enewetak Atoll. Locals call the dome a 'Tomb'.

'I hope this dome will not be our coffin,' said Jack Adding, Minister of Justice, Immigration and Labor in the Republic of the Marshall Islands. The half-life of plutonium-239 is 24,100 years.
