Just a few years ago, the northern Marshall Islands were known for their pristine coral reefs, little disturbed by human contact, in part because many of these isles were radiation no-go zones. Then, in 1957, the people of Rongelap returned. This was the worst radiological disaster in U.S. history and caused worldwide backlash against atmospheric nuclear testing. Copyright © 2019 by the Atomic Heritage Foundation. This affected nearby atolls and U.S. servicemen. A team of researchers from Columbia University has found that radiation levels from atomic testing in the Marshall Islands are still too high for human habitation.
Rongelap Atoll is just one example of how nuclear fallout and relocation affected the Marshallese. Radiation on Marshall Islands up to 1,000 times higher than Chernobyl or Fukushima. 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 … All rights reserved.In the 1970s, the U.S. began cleaning up Enewetak Atoll to make it habitable again. Ocean currents, weather conditions, and wind patterns contributed to this spread of fallout and debris. On each atoll there are a number of islands.Tour some of the key locations of the Manhattan Project with an audio guide.
Levels on Bikini, for example, were measured as high as 648 millirems per year. Due to Castle Bravo radioactive debris was released into the atmosphere, and to surrounding atolls. The residents were promised they could return one day, but realistically they had no choice in this matter. They further report that some of the levels were much higher than expected, and far exceeded the legal exposure limit that was agreed to by officials with both countries.

In 1954, as a result of the Castle Bravo test, many residents here suffered from burns and radiation diseases. The Marshallese have lived there for thousands of years. The Marshall Islands became the Republic of the Marshall Islands (RMI) in 1979.Browse our collection of oral histories with workers, families, service members, and more about their experiences in the Manhattan Project.During the post-World War II period the U.S. expanded their nuclear research and development programs.
However, officials and scientists working for the AEC concluded that radiation was still a risk.In 1946, Navy Commodore Ben Wyatt met with the 167 people living on Bikini Atoll. In 1914, Japan captured the Marshall Wyatt asked the Marshallese to relocate, and for use of their atoll “for the good of mankind.” He explained that they were a chosen people and that perfecting atomic weapons could prevent future wars.
Radioactivity still persists in parts of the Marshall Islands from nuclear testing in the 1940s and 50s, according to new research. Published in the journal PNAS, one of the three new papers states that while the background radiation levels are safe in the islands which are currently inhabited, gamma radiation persists in Bikini Atoll and other ground-zero test sites.
