Operation Castle
Operation Castle
US Dept. of Energy declassified film. "Operation Castle (aka Castle Bravo) was a 6-detonation test series held at the Atomic Energy's Pacific Proving Ground in the spring of 1954. This test series principally conducted at the Enewetak and Bikini atolls in the northwestern Marshall Islands, provided proof tests of large-yield thermonuclear or hydrogen bombs. ...Also, reports indicate that Bravo was the single worst incident of fallout in all of the US atmospheric testing program. Fallout was scattered over more than 7000 square miles of ocean and islands, resulting in the contamination and exposure of military, civillian U.S. personnel working on the shot, and the people of the islands who were earlier moved to a supposedly "safe" island but received large amounts of radiation."
