This is a more radioactive site than Chernobyl and Fukushima

In episode 4 of the Chernobyl miniseries produced by HBO, Soviet officials sat together to assess the damage of the nuclear power plant explosion in 1986.

The roof of the power plant has become "The most dangerous place on Earth"They argue. If a person stands there for two minutes, the amount of radiation will definitely cause him to halve his life.

However, the Soviet efforts to remedy the subsequent years proved to be effective. The construction of a giant concrete coffin encircled by the No. 4 reactor helped significantly reduce the level of radiation.

Although Chernobyl has so far maintained an area of ​​4,200 km of isolation2but abandoned schools, amusement parks and classrooms are open to tourists aged 18 and over.

"The amount of radiation you receive in a flight may be even greater [thời gian tham quan trong khu vực này]"Cork Corkhill, a nuclear waste treatment researcher at Sheffield University, said Corkhill is still supporting cleanup work at Chernobyl.

A nuclear test site on the Marshall Islands

But when the whole world was attracted to Chernobyl, little was known that there was an area even more dangerous in the world than the abandoned power plant in Ukraine. It was Marshall, an archipelago in the Pacific Ocean, where the US conducted 67 nuclear tests after World War II.

Recently, a study by scientists from Columbia University found that some Marshall Islands are more radioactive than Chernobyl. Soil samples in these 11 islands contain radioactive elements at "high level", including americium, cesium and two types of plutonium.

The highest radiation dose was found on Bikini Island, where the US conducted the biggest hydrogen bomb test, and then had to sink dozens of radioactive ships.

The radioactive elements found at Marshall are similar to the elements found at Chernobyl, after the explosion released about 5,300 petabecquerels of radioactive material into the surrounding environment.

Within 3 months after the Chernobyl disaster, more than 30 people died of acute radiation. Today, scientists estimate tens, even hundreds, of thousands of people have been seriously affected by the amount of radiation emitted from it.

The same story can be silently happening at Marshall that few people notice. The Columbia University analysis showed that some islands with higher levels of american-241 radioactivity than those found at Chernobyl in 2009.

The Marshall Islands are where the US has conducted 67 nuclear tests since the second world war

Their tests also showed that Bikini Island contained 1,000 times more plutonium than the amount of radiation detected at Chernobyl or Fukushima, which also occurred a disaster related to nuclear power plants in 2011 after Japan suffers from an earthquake and tsunami.

In addition, separate studies show that fruits on some Marshall Islands also have Caesium-137 content that exceeds international safety standards. Some islands also contain more cesium-137 than Chernobyl 10 years after the accident.

In the conclusion of the study, the scientists identified four northern islands of the archipelago – including Runit, Enjebi, Bikini and Naen – that are being polluted more seriously than the area near the Chernobyl power plant.

Although most of these islands are uninhabited, researchers recommend that people in Marshall's neighborhood should not come and "spend time"There. In addition, they also stated the government's responsibility to overcome the consequences and clean up this radioactive area.

The study was published in the Proceedings of the National Academy of Sciences.
