Operation Crossroads
There were only seven nuclear bombs in existence in July 1946. The two bombs used in the test were Fat Man plutonium implosion-type nuclear weapons of the kind dropped on Nagasaki. The "Able" bomb was stenciled with the name "Gilda" and decorated with an "Esquire" magazine photograph of Rita Hayworth, star of the 1946 movie, "Gilda". The "Baker" bomb was "Helen of Bikini." This femme-fatale theme for nuclear weapons, combining seduction and destruction, is epitomized by the use in all languages, starting in 1946, of "bikini" as the name for a woman's two-piece bathing suit.
Nagasaki Atomic Bomb Museum
The museum at the Nagasaki Peace Park replaced the Nagasaki International Culture Hall, where artifacts related to the bombing of Nagasaki were originally exhibited. These artifacts are now supplemented with photographs depicting daily life in Nagasaki before the atomic bomb was dropped, the devastation produced by the bomb, and the history of nuclear arms development.
