ambiguous statement...

From the article:

Only 408 personnel are said to have received no radiation following the test.

What the heck does this mean, or more to the point what was it supposed to mean?--Robert Merkel 00:01, 24 Nov 2004 (UTC)

Video?

The article talks about the shot being filmed, and that film being later released to the public. I have tried locating a copy of said film on the Internet, but only found one version of very low quality, with unneccessary background music and being just a few seconds long, too short to be interesting (Video). Does anyone have a copy of this film or knows where we could get one? --capnez 11:17, 29 Mar 2005 (UTC)

incorrect statement

I edited the sentence saying that "at 10.6 Megatons it is the largest detonation in history." It was not, in fact. That honor goes to the Czar Bomba at nearly FIFTY megatons.

"In history" can be somewhat complicated; sometimes it means "up to that point in history", sometimes not. Anyway it is clearly that particular meaning that is meant here and it should/could be clarified. --24.147.86.187 (talk) 23:04, 20 November 2007 (UTC)

Was Castle Bravo successful?

"that test was cancelled when the Bravo device was successful." Didn't that test exceed its design yield causing a severe nuclear incident? Hardly successful. Howboutpete 20:33, 20 April 2007 (UTC)

Successful in the sense that a dry fuel bomb could reach (what was then) extreme levels of yield. It was more than what they expected of what they wanted, and so successful. They cancelled the tests of the semi-cryogenic bombs, which required refrigeration apparatus, as obsolete. The unsuccessful part was their part; had they known that 15 Mt was possible from it, the identical test would have in no way been not a success. SkoreKeep (talk) 23:39, 16 February 2014 (UTC)

Depends how you define successful. If you mean, "a full-scale thermonuclear detonation of dry fusion fuel" then yeah, it was successful. --24.147.86.187 01:38, 14 June 2007 (UTC)

The wording could be more informative here. ".. a little (too) successful" is confusing. Does that imply that the US slowed down its nuclear program because of the casualties from Ivy Mike? If so, a citation would be very helpful. --joe056

Huh? No. It means that they didn't need to use the wet fuel bombs anymore. --24.147.86.187 (talk) 23:03, 20 November 2007 (UTC)

Incorrect statement

First the article says that the bomb was detonated on November 1, 1952

And then it says that Ivy Mike was the first of some 43 nuclear tests fired at Enewetak from 1948 to 1958.

The big question is: If this was the first bomb, then how did it detonate both 1948 AND 1952? Was it a hell of a bomb perhaps? —Preceding unsigned comment added by 217.208.228.170 (talk) 22:01, 13 November 2007 (UTC)

Whomever copied the info from the Enewetak article mangled it up. It was the first H-bomb test there (no surprise, it was the first in the world) but not the first nuclear test there. --24.147.86.187 (talk) 22:59, 20 November 2007 (UTC)

Mike Fireball??

Does there really need to be an article about the fireball? I've never seen it listed as a separate codename; it was the fireball of the MIKE shot, it doesn't need it's own article. --24.147.86.187 (talk) 22:57, 20 November 2007 (UTC)

Incorrect statement, as to who was President

Eisenhower was not yet President, or even President-elect, on November 1, 1952. —Preceding unsigned comment added by 173.69.61.160 (talk) 15:14, 2 October 2010 (UTC)

Maybe it means Eisenhower screened the film, after his term began.

I just tried editing the page, to reflect the correct physics of the device, but it got all shagged up. I would just like to point out, for my fellow wikipedians, that Richard Rhodes' book "Dark Sun" really gives an excellent explanation of what actually went on inside "The Sausage". For example, the low-density polyethylene did not get attached to the secondary casing, it was attached to the inside of the entire device casing, so that it could be converted to a plasma under hard x-ray bombardment and then re-radiate the absorbed energy as "soft", longer-wavelength x-rays, that ablated and in turn imploded the natural uranium seconday casing. This knowledge is public-domain, commonly-held, and should be correctly represented, especially given that Mike, whatever the moral qualms some may have, was a milestone of human civilization, and a brilliant accomplishment of engineering. Maybe I have to get better at editing. — Preceding unsigned comment added by Ajlocke2003 (talk • contribs) 05:14, 1 November 2012 (UTC)

The statement about who was president has now been clarified by a recent edit of mine.Anythingyouwant (talk) 00:48, 17 February 2014 (UTC)

Nuclear physics

Hello, I think it could be insteresting to add a section on the nuclear physics results which came with the explosion of Ivy Mike. Currently, there is only one sentence about it. For example, the fermium and the einsteinium were discovered thanks to this bomb. You may find some information in this paper. Pamputt (talk) 12:26, 27 September 2013 (UTC)

Rump project?

Can someone clarify what that is? Rodarmor (talk) 04:06, 17 December 2016 (UTC)

Impact on the islanders

There should be a section on the impact to the islanders themselves.

These are from a Marshallese activist's blog-- I know no original research but it may be good if someone wants to read these and look for more sources to corroborate /more work on the narrative of the impact to the islanders. It should be included.

Ivy Mike record breaking yield

I read somewhere that the Ivy Mike shot released more explosive power then every other man-made explosion in history, including every bomb, shell and rocket expended in WWI and WWII AND every other nuclear test to that date.

I would be happy to to research this and put add the necessary citation but I have not actually added new sections before, is there any guidance on where I would put this info ? Thanks in advance. — Preceding unsigned comment added by Rags17 (talk • contribs) 21:57, 12 May 2022 (UTC)

Confusion between Ivy Mike and Castle Bravo.

This article states Ivy Mike was the codename given to the first full-scale test of a thermonuclear device, in which part of the explosive yield comes from nuclear fusion.”, but Castle Bravo came first. They were different designs, but both thermonuclear. If someone just dropped in on this article alone they would be left with the impression that Ivy Mike was the first thermonuclear test. It wasn’t. It was a more practical, dry device, but not the first thermonuclear device tested. 72.168.145.39 (talk) 03:27, 26 February 2023 (UTC)

Hmm, NO! You seem to be confused here. Ivy Mike was THE first demonstration of the Teller-Ulam design and basically a physics field experiment. Castle Bravo came about 1.5 years later and demonstrated the first use of LiD fuel for a thermonuclear bomb, which ultimately lead to a practical and usable weapon design. 85.169.148.50 (talk) 02:57, 3 February 2024 (UTC)

I ran across someone making the same erroneous assertion a few months ago, and now I can’t find it. I’m not sure why it keeps coming up, but Ivy Mike was the first detonation of a Teller-Ulam-configured thermonuclear device, It was a test device, not a deployable weapon. That was 1952. Castle Bravo was also a test device, but more practical as a weapon, in 1954. Ivy Mike was a cryogenic device, Castle Bravo was a dry device. Acroterion (talk) 04:19, 3 February 2024 (UTC)
