Bikini Atoll


Bikini Atoll is a group of 23 islands in the Pacific that is forever linked with the nuclear age. Between 1946 and 1958, twenty-three nuclear devices were detonated at Bikini Atoll by the USA.

The local inhabitants were displaced and 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.

In 1968 the United States declared Bikini habitable and started bringing a small group of Bikinians back to their homes in the early 1970s as a test. In 1978, however, the islanders were removed again when strontium-90 in their bodies reached dangerous levels after a French team of scientists did additional tests on the island.

Prior to the explosion of the first atomic bomb on the island, the lagoon at Bikini was designated as a ship graveyard after World War II by the United States Navy. Today the Bikini Lagoon is still home to a large number of vessels.

  • Atoll 
  • Formerly inhabited islands Was first evacuated in Mar 1946 for the Atomic Tests which.In June 1968 LBJ promised the islanders that a clean up would enable them to return - this started in 1969. But in 1978 medical examinations identified high radiation levels in the population and another evacuation took place. In 1998 an IAEA advisory group "recommended that Bikini Island should not be permanently resettled under the present radiological conditions. This recommendation was based on the assumption that persons resettling on the island would consume a diet of entirely locally produced food." This remains the situation with Bikinians pursuing law suits against the US for a proper clean up. The atoll remains open with conditions for limited and self sufficient dive and sports fishing tourism
