In the world, there is a place 10 times more radiant than Chernobyl, that is the Marshall Islands. Even today, its not habitable, and thats all because of 67 U.S. nuclear tests there.

A nuclear waste landfill known as the grave

In the Marshall Islands, locals nicknamed lunits domed nuclear waste dump a grave.. The sealed pit contains more than 3.1 million cubic feet of radioactive waste, built by the U.S. military after cleaning up the dangerous debris left by the nuclear explosion.

From 1977 to 1980, about 4000 American soldiers were sent to clean up the nuclear test site of Eniwetok Atoll. They scooped up contaminated soil and other radioactive waste, put it all into the dome, and sealed it with concrete.

The radioactive waste in the pit is enough to fill 35 Olympic standard swimming pools. Most of them are plutonium bearing radioactive soils. Plutonium is an isotope, if inhaled by human body, it will lead to lung cancer and other diseases.

The dome is still uninhabited on the island

Before the nuclear tests of the 1940s and 1950s, residents of Eniwetok Atoll were moved to nearby islands. Today, only three of the atolls 40 islands are considered safe for human habitation. There are currently about 650 residents living there.

For decades, as the sea level in the region increased, the water began to seep into the soil under the dome. The bottom of the nuclear waste dump is not sealed with concrete like the top, so the rising sea water may submerge or even open the dump.

The breaking dome worried the locals

In 2013, the U.S. Department of energy reported that radioactive materials may leak from the dome into the marine environment. However, the report said that this situation does not necessarily lead to any significant changes in the radiation dose suffered by local residents.

The sea level around the Marshall Islands is rising and has risen by about 7 mm a year since 1993. By 2030, sea levels could be 1.2 to 6.3 inches (0.03 to 0.16 meters) higher than they are now, leading to more storm surges and coastal flooding. By 2100, the dome could be submerged by sea water.

Local residents are concerned that a series of new health risks may arise from the continuous destruction of buildings. Recently, the dome began to crack and notch, which also increased the possibility of it being opened by strong waves. If the dome is damaged, there will be more radioactive waste discharged into the nearby ocean or lagoon, which may even force the local people to leave their hometown again.

If the dome does crack, most of the people here will no longer exist, said a teacher at Eniwetok Atoll. Its like our graveyard. We can only wait for death.

Scientists dont know if the radiation from the dome is harmful

Marine radiochemist Ken buesseler, who is planning to sample soil near the dome, recently told the media that concerns about radiation levels may have been exaggerated. In fact, he claims, everything you eat contains cesium and plutonium.

In the event of a disaster, the residents of Eniwetok Atoll will have to inhale the leaked plutonium or be exposed to polluted water, which may bring them health hazards. But scientists are still studying the overall effects of radiation on the islands.

You cant taste, smell, touch or feel it, its an invisible thing and its harmful to human health, no one wants it to happen, buesseler said

Chernobyl radiation scary? This Pacific archipelago is 1000 times higher than it

When it comes to the highest radiation levels on earth, you may immediately think of Chernobyl and Fukushima. However, the latest research shows that radiation levels are even more alarming in parts of the Marshall Islands in the middle of the Pacific Ocean. During the cold war, the United States conducted as many as 67 nuclear tests there.
