Rongelap Atoll / ˈ r ɒ ŋ ɡ əl æ p / RONG -gə-lap ( Marshallese : Ron̄ļap , [rʷɔŋʷ(ɔ)lˠɑpʲ] ) is an uninhabited coral atoll of 61 islands (or motus ) in the Pacific Ocean , and forms a legislative district of the Ralik Chain of the Marshall Islands . Its total land area is 8 square miles (21 km). It encloses a lagoon with an area of 1,000 square miles (2,600 km). It is historically notable for its close proximity to US hydrogen bomb tests in 1954, and was particularly devastated by fallout from the Castle Bravo test. The population asked the US (several times) to move them from Rongelap following the test due to high radiation levels, but with no success; so they asked global environmental group Greenpeace to help. The Rainbow Warrior made three trips moving the islanders, their possessions and over 100 tons of building materials to the island of Mejato in the Kwajalein Atoll , 180 kilometers away.
