After the inhabitants agreed to a temporary evacuation, to allow nuclear testing on Bikini
The 167 people who lived on Bikini were instructed to leave so the military could test nuclear bombs,[3] a forced relocation.[4] In 1946 they moved to Rongerik, a small island east of Bikini Atoll, but it turned out to have inadequate resources to support the population. The islanders began experiencing starvation by early 1948 and were moved again to Kwajalein Atoll.[5] The United States used the islands and lagoon as the site of 23 nuclear tests until 1958, when it was discovered that the fallout from nuclear testing was much more dangerous than was previously thought. To this day, the Bikini islanders are prohibited from returning home due to nuclear contamination. There are some signs of recovery as the amount of radiation slowly decreases.
There have been nuclear tests from derelict ships, right? I wonder what the need for the atoll was.
