Is It Safe To Do Use Nuclear Weapons (Atomic bombs and what not) Undersea?

Question

I know using atomic bombs and such on land is dangerous, what about underwater :\

Answer 1

No, most of the worlds biomass is in the oceans.

Water currents would spread the contamination as well

Answer 2

perhaps not as bad but still bad.   Bikini Island is well-known for being the subject of nuclear bomb tests, and because the bikini swimsuit was named after the island in 1946. The two piece swimsuit was introduced within days of the first nuclear test on the atoll, and the name of the island was in the news.[1] Introduced just weeks after the one-piece "Atome" was widely advertised as the "smallest bathing suit in the world", it was said that the bikini "split the atome".[2]

Between 1946 and 1958, twenty-three nuclear devices were detonated at Bikini Atoll. The March 1st, 1954 detonation codenamed Castle Bravo, was the first test of a practical hydrogen bomb. The largest nuclear explosion ever set off by the United States, it was much more powerful than predicted, and created widespread radioactive contamination[3]. Among those contaminated were the 23 crewmembers of the Japanese fishing boat The Fifth Lucky Dragon. The ensuing scandal in Japan was enormous, and ended up inspiring the 1954 film Godzilla, in which the 1954 U.S. nuclear test awakens and mutates the monster, who then attacks Japan before finally being vanquished by Japanese ingenuity.

The Micronesian inhabitants, who numbered about 200 before the United States relocated them after World War II, ate fish, shellfish, bananas, and coconuts. A large majority of the Bikinians were moved to a single island named Kili as part of their temporary homestead, but remain until today and receive compensation from the United States for their survival.[4]

In 1968 the United States declared Bikini habitable and started bringing a small group of Bikinians back to their homes in the early 1970s as a test. In 1978, however, the islanders were removed again when strontium-90 in their bodies reached dangerous levels after a French team of scientists did additional tests on the island.[5]. It was not uncommon for women to experience faulty pregnancies, miscarriages, stillbirths and damage to their offspring as a result of the nuclear testing on Bikini.[6] The United States provided $150 million as a settlement for damages caused by the nuclear testing program.[7]

The clean-up operation scraped off the top 16 inches (410 mm) of soil from the main island of Bikini, generating a million cubic feet of radioactive soil that could not be disposed of, at a cost that far  

Answer 3

Man, What Not is OK, leave the radiation topside.

Answer 4

no
