Some of the Marshall Islands in the Pacific Ocean — such as the Bikini and Enewetak atolls — are still more radioactive than Chernobyl and Fukushima , even though more than 60 years have passed since the United States tested radioactive weapons on those islands, a new study finds. When testing the soil for plutonium and , the researchers found that some of the islands had levels that were between 10 and 1, times higher than those on Fukushima where an earthquake and tsunami led to the meltdown of nuclear reactors and about 10 times higher than levels in the Chernobyl exclusion zone. The researchers took only a limited number of soil samples, meaning a more comprehensive survey is needed, they said. Regardless, they were surprised that neither national governments nor international organizations had "any further guidance on permissible plutonium levels in the soil," even though levels in the Marshall Islands were high, the researchers wrote in the study. After dropping atomic bombs on the Japanese cities of Hiroshima and Nagasaki in , effectively ending World War II, the United States decided to test more radioactive weapons.
Nuclear Testing at Bikini Atoll

After the displacement of the local inhabitants, 67 nuclear tests were carried out from to , including the explosion of the first H-bomb Bikini Atoll has conserved direct tangible evidence that is highly significant in conveying the power of the nuclear tests, i. Equivalent to 7, times the force of the Hiroshima bomb, the tests had major consequences on the geology and natural environment of Bikini Atoll and on the health of those who were exposed to radiation. Through its history, the atoll symbolises the dawn of the nuclear age, despite its paradoxical image of peace and of earthly paradise. In het kielzog van de Tweede Wereldoorlog en in de aanloop naar de Koude Oorlog, besloten de Verenigde Staten van Amerika om kernproeven in de Stille Oceaan voort te zetten op het Bikini atol van de Marshall eilanden.

This bomb consumed the infamous Demon core that caused the death of two scientists in two separate criticality accidents. The size of the Castle Bravo test on 1 March far exceeded expectations, causing widespread radioactive contamination. The fallout spread traces of radioactive material as far as Australia, India and Japan, and even the United States and parts of Europe. Though organized as a secret test, Castle Bravo quickly became an international incident, prompting calls for a ban on the atmospheric testing of thermonuclear devices. The nuclear weapons testing at Bikini Atoll program was a series of 23 nuclear devices detonated by the United States between and at seven test sites.
