The test left a 300 foot wide, 90 foot deep crater in the lagoon bottom.This device - designated Runt II - was a proof test of the TX/EC-24, the sister design of the Runt I TX/EC-17 which was fired in Romeo. Wikipedia. The subsample precipitate was dissolved in acid, and the elements were subsequently separated by ion exchange resins. Castle Koon; Information; Country: United States: Test series: Operation Castle: Test site: Bikini Atoll: Date: April 7, 1954: Test type: Atmospheric: Yield: 110 kt: Test chronology ← Castle Romeo. The task was performed at depths down to ∼60 m in low-visibility conditions.

A dash followed by a number indicates a member of a salvo event.

These results are used to create radiation maps of the Bravo crater, allowing for a more detailed and systematic discussion of radioactive contamination from thermonuclear weapons testing.On August 1, 2018, we surveyed the depth of the Bravo crater using a JMC V108 video echo sonar installed underneath the hull of a 23-m research vessel, Interpolated depth map of the Bravo crater based on echo sonar measurements (black dots).A total of 129 cores was collected in the Bravo crater over 2 y, in 2017 and 2018. The reason for this was that it used inexpensive and abundant unenriched natural lithium (7.5% Li-6) in the lithium deuteride fusion fuel. The fireball/mushroom cloud had quite a variety of condensation structures associated with it. In some cases it is not clear if the height is absolute or relative to ground, for example, Atmospheric, airdrop, balloon, gun, cruise missile, rocket, surface, tower, and barge are all disallowed by the Include weapons development, weapon effects, safety test, transport safety test, war, science, joint verification and industrial/peaceful, which may be further broken down.Designations for test items where known, "?" Topic. This incident created an international uproar, and a diplomatic crisis with Japan.The entire Bikini Atoll was contaminated to varying degrees and plans for conducting test operations from the islands, including use of the firing bunker, had to be abandoned. 7 Mt of its yield was fission (51.9%), the same as for Romeo.This how the deployed Mk-17/24 weapon family appeared.The Zombie device tested in Nectar was a prototype of the TX-15 lightweight thermonuclear weapon. The Bravo bomb was the second large-scale thermonuclear weapon test performed, following the first test, code named Ivy Mike, whose yield was 10.4 megatons. When one of these high energy neutrons collided with a lithium-7 atom, it could fragement it into a tritium and a helium atom. indicates some uncertainty about the preceding value, nicknames for particular devices in quotes. For rocket bursts the ground level is "N/A". Due to failures in forecasting and analyzing weather patterns, failure to postpone the test following unfavorable changes in the weather, and combined with the unexpectedly high yield and the failure to conduct pre-test evacuations as a precaution, the Marshallese Islanders on Rongelap, Ailinginae, and Utirik atolls were blanketed with the fallout plume, as were U.S. servicemen stationed on Rongerik.Within 15 minutes after the test radiation levels began climbing on Eneu Island, site of the test control bunker, which was supposed to be upwind from the test and thus immune to fallout. This fusion yield was the largest such yield of any device tested up to this time, larger than any Castle test, and set a U.S. fusion yield record that held until the Hardtack Poplar test in 1958. The crater was 990 feet wide and 75 feet deep.

The principal difference was the choice of thermonuclear fuel. "~" indicates a likely pro-forma rough location, shared with other tests in that same area.Elevation is the ground level at the point directly below the explosion relative to sea level; height is the additional distance added or subtracted by tower, balloon, shaft, tunnel, air drop or other contrivance.

In this picture 3 ice caps and 2rings are seen.Contour lines show the cumulative radiation dose in roentgens (R)for the first 96 hours after the test.Like Bravo, Romeo's explosive power far exceeded original projections - in fact it did so by an even larger factor, almost tripling the best guess yield.
