The island residents had been promised that they would be able to return home to Bikini, but the government thwarted that indefinitely by deciding to resume nuclear testing at Bikini in 1954. During 1954, 1956, and 1958, 21 more nuclear bombs were detonated at Bikini, yielding a total of 75 Mt of TNT (310 PJ), equivalent to more than three ...
Operation Crossroads was a pair of nuclear weapon tests conducted by the United States at Bikini Atoll in mid-1946. They were the first nuclear weapon tests since Trinity on July 16, 1945, and the first detonations of nuclear devices since the atomic bombing of Nagasaki on August 9, 1945.
Six very large nuclear tests were conducted at the Bikini Atoll and the Enewetak Atoll as part of Operation Castle in 1954. The most notable was Castle Bravo, which was the first deployable (dry fuel) hydrogen bomb developed by the United States. Its yield, at 15 Mt, was over twice as powerful as was predicted, and remains the largest weapon ...
The final test in the Grapple Z series was of Burgee, at 09:00 on 23 September 1958. This was another balloon-borne test detonated over the south east corner of Christmas Island. Burgee was an atomic bomb boosted with gaseous tritium created by a generator codenamed Daffodil. It had a yield of about 25 kilotonnes of TNT (100 TJ).

A third nuclear test called Charlie was called off after the first two. These were the last tests until 1954, when, the unexpectedly powerful hydrogen bomb was tested. [58] When the first hydrogen bomb was tested at Bikini Atoll in 1954, it turned out to be several times more powerful than expected which created a lot of problems. [58]
It includes nuclear test sites, nuclear combat sites, launch sites for rockets forming part of a nuclear test, and peaceful nuclear test (PNE) sites. There are a few non-nuclear sites included, such as the Degelen Omega chemical blast sites, which are intimately involved with nuclear testing. Listed with each is an approximate location and ...
The intense thermal flash ignited a fire at a distance of 20 nautical miles (37 km) on the island of Eneu (base island of Bikini Atoll). [6] The ensuing fallout contaminated all of the atoll, so much so that it could not be approached by JTF-7 for 24 hours after the test, and even then, exposure times were limited. [ 7 ]
