Castle Bravo is the sixth largest nuclear explosion in history, exceeded by the Soviet tests of Tsar Bomba at approximately 50 Mt, Test 219 at 24.2 Mt, and three other (Test 147, Test 173 and Test 174) ≈20 Mt Soviet tests in 1962 at Novaya Zemlya.
The most notable event of Operation Castle was the Castle Bravo test. The dry fuel for Bravo was 40% Li-6 and 60% Li-7. Only the Li-6 was expected to breed tritium for the deuterium-tritium fusion reaction; the Li-7 was expected to be inert.
Path of the nuclear fallout plume after the Castle Bravo test: the large plume lead to evacuations of additional atolls. The Rongelap Atoll was coated with up to 0.8 in (2.0 cm) of snow-like irradiated calcium debris and ash over the entire island. Virtually all the inhabitants experienced severe radiation sickness, including itchiness, sore ...
The Tsar Bomba far surpassed the largest explosion the United States has ever conducted - a 15-megaton "Castle Bravo" hydrogen bomb detonated on Bikini Atoll in 1954. (Reporting by Maria Vasilyeva ...
Half Life: A Parable for the Nuclear Age is a 1985 Australian documentary film directed by Dennis O'Rourke, concerning the American Castle Bravo nuclear testing at the Marshall Islands in 1954. The film features interviews with residents of the nearby Rongelap and Utirik Atolls who were affected by nuclear fallout from the tests.
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 cover to the Project 4.1 Final Report, "Study of Response of Human Beings Accidentally Exposed to Significant Fallout Radiation" Project 4.1 was the designation for a medical study and experimentation conducted by the United States of those residents of the Marshall Islands exposed to radioactive fallout from the 1 March 1954 Castle Bravo nuclear test at Bikini Atoll, which had an ...
Daigo Fukuryū Maru (第五福龍丸, F/V Lucky Dragon 5) was a Japanese tuna fishing boat with a crew of 23 men which was contaminated by nuclear fallout from the United States Castle Bravo thermonuclear weapon test at Bikini Atoll on March 1, 1954. The crew suffered acute radiation syndrome (ARS) for
