By Paul Benecki To commemorate the seventieth anniversary of the first Bikini Atoll nuclear tests, the nonprofit National Security Archive has published declassified footage of the Able and Baker "shots" in the summer of The relatively small explosions by nuclear standards sank 15 out of 95 ships deployed, severely damaged many of the rest, and so thoroughly contaminated others with radioactive fallout that they had to be scuttled rather than scrapped.
Operation Crossroads, which had its first big event—the dropping of a nuclear bomb—on July 1,was just the beginning of the nuclear testing that Bikini Atoll would be subjected to. When the first bomb of the tests dropped, it was the first time since the attacks on Japan that a nuclear weapon had been deployed. Here are three things you might not know about the infamous tests:.
Sixty years ago today, the United States detonated a hydrogen bomb that altered the landscape, hundreds of lives, and the trajectory of a nuclear arms race. On March 1,the U. Army detonated a thermonuclear bomb on Bikini Atoll in the Marshall Islands.
An analysis of soil samples, ocean sediment, and fruits from the Marshall Islands—the site of nearly 70 nuclear weapons tests during the s and s—has revealed alarmingly high levels of radiation, with some regions at levels exceeding areas affected by the Fukushima and Chernobyl disasters. From tothe United States conducted 67 nuclear tests in the Marshall Islands, a series of atolls located north of the equator between Hawaii and Australia. Twenty-three of these tests were conducted at Bikini Atoll and 44 near Enewetak Atoll, but fallout spread throughout the entire Marshall Islands, exposing the indigenous people there to dangerous levels of radiation.
At a. Within seconds, a mushroom cloud towered seven kilometres high over Bikini Atoll in the Marshall Islands. The explosion, the U.
Washington, D. The Baker test caused a radiological crisis because task force personnel were assigned to do salvage work on contaminated test ships. Recently declassified documents shed light on the emerging Cold War atmosphere; one of the observers, Simon Peter Alexandrov, who was in charge of uranium for the Soviet nuclear project, told a U.
The nuclear testing at Bikini Atoll program was a series of 23 nuclear weapons detonated by the United States between and at seven test sites on the reef itself, on the sea, in the air, and underwater. The United States was engaged in a Cold War nuclear arms race with the Soviet Union to build more advanced bombs from until The second was Baker and was suspended under a barge.

Between and the atolls of the Marshall Islands in the Pacific Ocean were testing ground for the United States nuclear arsenal. The first bomb, called Able, was detonated July 25,on Bikini Atoll.
Some of the Marshall Islands, where the U. Made up of two chains of atolls comprised of over 1, small islets, the Marshall Islands sit in the central Pacific Ocean between Hawaii and the Philippines. Following the Second World War, the U.
How can you tell if a painting is a modern forgery? Midth-century nuclear bomb tests may hold a clue. For years, scientists have been refining techniques to determine the age of a painting using radiocarbon dating and the lingering effects of the tests. Now, a team of researchers has dated one such artwork using a paint chip the size of a poppy seed, according to a study published on Monday in The Proceedings of the National Academy of Sciences.
