Nuclear testing in the Marshall Islands: displacement and fallout
U.S. nuclear testing transformed Bikini and Enewetak and exposed Marshallese communities to displacement and radioactive contamination.

A testing ground was already a homeland
U.S. authorities relocated Bikini’s inhabitants before Operation Crossroads in 1946. Between 1946 and 1958, the United States carried out 67 nuclear tests in the Marshall Islands: 23 at Bikini and 44 at or near Enewetak. The total for the Marshall Islands must not be presented as the number conducted at Bikini alone.
Castle Bravo and its consequences
The Castle Bravo test at Bikini on 1 March 1954 produced a much larger explosion than expected. Radioactive fallout contaminated inhabited islands and the Japanese fishing boat Lucky Dragon No. 5. The blast’s effects crossed the boundaries of the designated test area, exposing the inadequacy of treating island communities as remote from the experiment.
Beyond the mushroom cloud
Displacement, contamination and the struggle to return home are central to this history. A photograph of a detonation cannot by itself explain those experiences. This study covers the U.S. Marshall Islands programme; British and French Pacific testing had separate sites, dates and affected communities and require their own accounts.
