What happened to the rest of the crew? --Khazar 07:20, 15 January 2006 (UTC)

I was wondering the same thing. The closest I've been able to find for a follow-up is here, via a Google search. --138.28.140.198 07:34, 6 February 2006 (UTC)

According to a google translate of the japanese wikipedia:

"Health investigation after the accident 22 people fifth Lucky Dragon survivors, has been carried out in the long run continuously by the National Institute of Radiological Sciences. In addition, according to the Research Institute of the Akashi mantra colleagues in 2004, 12 people died by 2004, six liver cancer, two cirrhosis of the liver, one liver fibrosis, one colon cancer, which consisted of, heart failure 1 person is a traffic accident one person. In addition, there is a liver dysfunction to many of the survivors, the hepatitis virus test, positive rate is abnormally high A, B, C-type both."

Maybe someone is able to a proper translation of original Japanese sources? Praseodym (talk) 08:00, 13 May 2014 (UTC)

only victim hydrogen bomb?

He is considered to be the first victim of a hydrogen bomb, but I was wondering : what others are there (apart from other crewmembers of course)?

I understand that this is not such an easy question, one is never sure how much radiation has contributed to someone's earlier death

I have a problem with the part of the article that claims that Aikichi Kuboyama died of acute radiation poisoning. There was considerable controversy at the time regarding whether the problem was exposure to radiation or an underlying problem with his liver. The fact that he died seven months after initial exposure suggests that it wasn't acute radiation syndrome, since that kills within two weeks (according to what I know and the link provided at the least).

As for whether Kuboyama was the "first victim", it depends on how you define the word victim. Several of the crew members exhibited signs of radiation sickness, but they recovered with medical assistance. Are they victims because they were ill or are we only talking about fatalities? Since the Bravo Shot had a higher than expected yield (15 megatons rather than 4-6), the fallout zone was wider than expected, which resulted in the forced relocation of people living in nearby islands, so they could be considered victims as well.

To my knowledge, the other members of the crew were treated for radiation poisoning and released without (seemingly) any long-term effects. I've never read about any of them getting cancer thereafter, but I don't know for sure.

About 100 Boats? Guess again

From the City of Hiroshima official website on the matter:

The Lucky Dragon No. 5 was not the only victim of the hydrogen bomb test. By the end of December 1954, 856 boats had been exposed to radiation from testing. Called "A-bomb tuna," roughly 490 tons of the fish caught by these boats had to be discarded. Around Japan, various people related to the fishing industry saw their sales fall and raised their voices in anger. Around May, rain containing radioactive material began falling, intensifying the climate of fear in Japan.

Distance from ground zero?

How far was the lucky dragon no.5 from ground zero? What was the circumference of the US imposed danger zone? Can anyone fill these gaps? (Downs 22:19, 28 July 2006 (UTC))

Disputed/Dubious Test Site Contanimation

Someones trolled this article... Im just a wiki noob but the article says:

"He noted that they were taking a long time to die, and when finally dead, appeared to still have some life in them. Dr. Nishiwaki claimed to have witnessed some dead crew members twitch or actually come back to life and attack medical staff by trying to eat them alive. Some of these medical staff members that died would also either twitch or come back to life and attempt to eat anyone alive within their reach. The US vehemently denied these events and did not respond to Nishiwaki's letter or to letters from other Japanese scientists requesting information and help.[9]"

Zombies... o_O maybe someone that knows how to wiki can fix it 188.122.38.102 (talk) 14:37, 28 September 2012 (UTC)wikin00b

I can't find any references to people becoming zombies in this incident, as indicated in the middle to bottom of this section. --173.53.70.114 (talk) 19:12, 29 September 2012 (UTC)

Thanks for noticing this. It was the work of a hoaxer editing from an anonymous address. JoshuSasori (talk) 23:31, 30 September 2012 (UTC)

Composition

I would like to point out that the German composer Herbert Eimert composed an excellent piece entitled "Epitaph für Aikichi Kuboyama (1960-1962)", you can listen to it here Epitaph, part 1, here Epitaph, part 2 and here Epitaph, part 3.--Rubycon67 (talk) 07:50, 15 October 2012 (UTC)

Compensation

This article says "After negotiations with the Japanese side, the United States paid each surviving crew member 2 million yen on average as sympathy money in a political settlement." --Esemono (talk) 12:12, 15 October 2012 (UTC)

Hmm, the reference doesn't say anything about the negotiations proceeding swiftly, and you also removed the referenced content about the payment to the widow. Also you got the yen/dollar exchange wrong. Not a great edit. JoshuSasori (talk) 12:42, 15 October 2012 (UTC)

Really? I'm basing it from 1949–71 the Yen was pegged to the american dollar at 360. What info are you using? -- Esemono (talk) 13:29, 15 October 2012 (UTC)

What info are you using? The actual exchange rate now. As I have stated above, I believe your edits are poor quality and diminish the article. JoshuSasori (talk) 22:15, 15 October 2012 (UTC)

Why would you use today's exchange rate for transaction that happened decades ago? That makes no sense. -- Esemono (talk) 04:02, 16 October 2012 (UTC)

Attempting to increase accuracy of article

I've completed a few edits of this article recently and wanted to state here that this article really needs some strong medical references WP:RSMED to support the notion that Aikichi Kuboyama died of acute radiation syndrome(ARS) and not his underlying liver disease.

I see here on the talk page history that this dispute over whether it was ARS or due to his liver cirrhosis is an old one and needs to be explained to readers.

Furthermore, having noticed here on the talk page that people want to know the health history of the other 22 crew members, I've added a "health history" section to the article and filled in a little detail on two surviving crew members.

I will also add a map in a few minutes to give readers an estimate on how far away the ship was from Castle Bravo's ground zero. I don't think it is known with a great degree of accuracy exactly where the Lucky Dragon no.5 was at the time of the detonation, and at the time of fallout arriving at their location, nor is it known how long they stayed and continued to fish in the area, oblivious to the danger after the fallout arrived.

If we can find a reference stating the length of time between when fallout arrived at their location and they first began showing symptoms of ARS, such as vomiting, I can provide a reference that will estimate their total absorbed dose.

Updated Article as Research Project

Hello everyone,

I have updated the article. I added to several sections, removed a section, and created two new sections. I updated the history of the ship after it returned to Japan including the history of the crew. I adjusted the names in the article so they now show the correct Japanese form.

The ship post contamination

What happened to the ship post-contamination doesn't make sense. First it says "On August 22, the ship was purchased by the Japanese government and towed to the Tokyo University of Fisheries.[28] In 1956, the ship was refitted and renamed as Hayabusa Maru and put to use as a training vessel." But then 2 paragraphs later: "On June 11, 1970, the Lucky Dragon No.5 received media attention as it still sat in garbage within the canal."

What canal? what garbage? What happened to it being a training vessel? Something is missing here. IneedAuserName4WikiAndIChooseYouPikachuButNotAsh (talk) 03:34, 13 November 2021 (UTC)
