Summary

Description
English: The "Baker" explosion, part of Operation Crossroads, a nuclear weapon test by the United States military at Bikini Atoll, Micronesia, on 25 July 1946. The wider, exterior cloud is actually just a condensation cloud caused by the Wilson chamber effect, and was very brief. There was no classic mushroom cloud rising to the stratosphere, but inside the condensation cloud the top of the water geyser formed a mushroom-like head called the cauliflower, which fell back into the lagoon (compare with this image, a photo taken slightly later, after the condensation cloud had cleared). The water released by the explosion was highly radioactive and contaminated many of the ships that were set up near it. Some were otherwise undamaged and sent to Hunter's Point in San Francisco, California, United States, for decontamination. Those which could not be decontaminated were sunk a number of miles off the coast of San Francisco.
Français : L'explosion atomique Baker, déclenchée dans le cadre de l'Opération Crossroads, une série d'essais nucléaires menés par les États-Unis sur l'atoll de Bikini, dans les Îles Marshall le 25 juillet 1946. Le large nuage blanc est un nuage de condensation (Nuage de Wilson) qui n'a duré qu'un temps très court. L'explosion n'a pas formé un champignon atomique classique, mais une colonne d'eau qui s'est étalée « en chou fleur » puis est retombée dans le lagon. L'image est à comparer avec celle-ci, prise après la disparition du nuage de condensation. L'eau déplacée par l'explosion était fortement radioactive et a contaminé les bateaux qui avaient été placés à proximité. Les bateaux contaminés, mais en état de marche, ont été emmenés vers les chantiers de Hunter's Point, à San Francisco, pour y être décontaminés. Ceux qui n'ont pas pu être décontaminés ont été coulés au large de la ville.
Italiano: La nuovola di condensazione provocata dalla detonazione nucleare sottomarina “Baker” (23 chilotoni) che avvenne il 25 luglio 1946 nell'ambito dell'Operation Crossroads, una serie di test nucleari condotti dalle forze armate statunitensi sull'atollo di Bikini, nelle Isole Marshall.
Deutsch: Die "Baker"-Explosion, Teil der Operation Crossroads, einem Kernwaffentest des US-Militärs auf dem Bikini-Atoll, Mikronesien, am 25. Juli 1946. Die breitere, äußere Wolke ist eigentlich nur eine Kondensationswolke, die durch den Wilson-Kammer-Effekt verursacht wird, und war sehr kurz. Es gab keinen klassischen Atompilz, der in die Stratosphäre aufstieg, aber innerhalb der Kondensationswolke bildete die Spitze des Wassergeysirs einen pilzähnlichen Kopf, der Blumenkohl genannt wurde und in die Lagune zurückfiel (siehe zum Vergleich ein Bild, das etwas später aufgenommen wurde, nachdem sich die Kondensationswolke aufgelöst hatte). Das durch die Explosion freigesetzte Wasser war hochradioaktiv und kontaminierte viele der Schiffe, die in der Nähe ankerten. Einige blieben abseits der Kontamination unbeschädigt und wurden zur Dekontamination nach Hunter's Point in San Francisco, Kalifornien, USA, geschickt. Diejenigen, die nicht dekontaminiert werden konnten, wurden einige Meilen vor der Küste von San Francisco versenkt.

Català: L' explosió “Baker”, part de l'Operació Crossroads, un assaig d'armes nuclears per part de militars dels Estats Units a l'atol de Bikini, Micronèsia, el 25 de juliol de 1946. El nuvol més ampli i exterior és en realitat un núvol de condensació causada per l'efecte de cambra de Wilson, i va ser molt breu. No hi havia cap núvol de fong clàssics arribant a l'estratosfera, però dins de la condensació dels núvols de la part superior del guèiser d'aigua es formà un cap de fong anomenat la coliflor, que va tornar a caure en la llacuna (comparar amb aquesta imatge, una foto presa poc després, la condensació dels núvols s'havia aclarit). L'aigua alliberada per l'explosió era altament radioactiva i contaminà molts dels vaixells que s'hi havien posat aprop. Alguns estaven per altra part en bon estat i s'enviaren a Hunters Point a San Francisco, Califòrnia, Estats Units, per a la descontaminació. Aquells que no van poder ser descontaminats es van enfonsar a un nombre de milles de la costa de San Francisco.
