From 1946 to 1958, the Bikini Atoll–a Micronesian, volcanic island group in the Pacific Ocean (part of the Marshall Islands)–was “home” to twenty three, U.S.-conducted, nuclear detonations, including the first true Hydrogen bomb test, in 1954. This latter detonation produced an explosion far more powerful than originally predicted and caused wide-spread contamination from radioactive fallout.
