The Japanese wanted compensation. Additionally, this was proof of the radioactive dangers of these thermonuclear bombs. Armed Forces Special Weapons Project. OPERATION CASTLE. Albuquerque, NM, 1959. ​ ​ Accessed August 28, 2019. http://large.stanford.edu/courses/2012/ph241/garcia2/docs/0201_a.pdf. Operation Castle was initiated as a consequence of Operation Ivy, and was used to confirm Operation Ivy's data. This technical report further explained the purpose and went into detail about the execution of Operation Castle. Although it focuses more on Operation Castle, it shows how integral the information gathered by Operation Ivy was to further development of thermonuclear bombs.

Elugelab is completely vaporized after Ivy Mike is detonated on November 1, 1952. This horrific set of images captures string of atolls in the Marshallese islands before and after Ivy Mike. In the after photo, Elugelab has been completely wiped off the map, demonstrating the environmental distress caused by Operation Ivy. Bikini atoll crater from Castle Bravo. Photograph.

This picture is a satellite image of current Bikini atoll which contains a giant crater from Castle Bravo. This is crucial supplementary evidence to prove how devastating the thermonuclear bombs were. This also puts into perspective the sheer power of Operation Castle’s bombs: an improvement upon this. The Boston Daily Globe. Accessed September 18, 2019. ​ https://www.atomicheritage.org/history/hydrogen-bomb-1950. The H-Bomb utilizes a trigger that generates heat to set off the thermonuclear fusion, as detailed by this article praising the AEC. It is stated that the AEC had started another project for the hydrogen bombs, presumably Operation Ivy. This helps to demonstrate the magnitude of tension built by mutually assured destruction so hauntingly real during the Cold War. Castle Bravo Detonation. March 1, 1954. Photograph. Accessed August 25, 2019. ​ https://nuclearweaponarchive.org/Usa/Tests/BravoC167c10.jpg. This is the mushroom cloud and resulting fireball from Castle Bravo's detonation. The image demonstrates the devastating power that these experiments were causing, leading us to the conclusion that the experiments so close to inhabited land was an obvious violation of human rights against the Bikinians. Crawl Out Through the Fallout. By Sheldon Allman. 1960, compact disc. Accessed ​ January 31, 2020. https://www.youtube.com/watch?v=8XPzICHxXoQ. This song, Crawl Out Through the Fallout, illustrates the impact that the idea of having nuclear war had on people. They wanted to express the idea of nuclear war as something comedic and commonplace. This song details the aftermath of nuclear war. In addition to this, this was not the only song about nuclear war to be published throughout the Cold War, creating a rather sad normalization of the reality of possible nuclear annihilation. 3 Department of Commerce Weather Bureau.

Accessed August 28, 2019. http://large.stanford.edu/courses/2012/ph241/garcia2/docs/51383e.pdf. Operation Castle was supposed to be an improvement of Ivy: more powerful and overall better technology. The debris in the atmosphere was significantly less from Operation Ivy to Operation Castle. This kind of technological improvement undoubtedly played a big factor in the tensions of the Cold War. Department of Defense Defense Nuclear Agency. Operation Ivy 1952. 1952. Accessed August ​ ​ 18, 2019. https://www.dtra.mil/Portals/61/Documents/NTPR/2-Hist_ Rpt_Atm/1952_DNA_6036F.pdf. Ivy Mike was the first ever thermonuclear bomb to be detonated. It created a surface level explosion that produced 10.4 megatons of force, equal to the explosive force of 10,400,000 tons of TNT. 15 years after the blast, leukemia and radiation was found to becoming increasingly prevalent among those who were present for those who participated in the operation. Operation Ivy was a test to push the limits of nuclear technology as well as learn to measure radiation. Hoover, Will. "Bikini Atoll survivors recall horror of nuclear explosion." Honolulu Advertiser ​ (Honolulu, HI), March 2, 2003. Accessed September 18, 2019. http://the.honoluluadvertiser.com/article/2003/Mar/02/ln/ln05a.html. The people of the Marshall Islands were not properly informed about the tests resulting in their radiation, among other negative impacts. There were jellyfish babies born due to the radiation, which was traumatic. There were also susceptibilities to cancer. This is further documentation of the human rights violation of Operation Castle. 4 The images contain physicians responsible for the creation of H-Bombs. Photograph. Accessed September 18, 2019. https://www.atomicheritage.org/history/hydrogen-bomb-1950. Isidor Rabi was an American physicist. He had won the Nobel Prize for Physics in 1944. He had discovered nuclear magnetic resonance, used for magnetic resonance imaging. Hans Bethe was a man who's work correlated with the theory of atomic nuclei. He had developed a theory of deuteron in 1934, later expanding the study in 1949. Klaus Fuchs was a physician in charge of studying the effects that thermonuclear reactions produce on the Earth. Ivy King Fireball. November 1, 1952. Photograph. Accessed August 25, 2019. ​ https://nuclearweaponarchive.org/Usa/Tests/Iking3.jpg. This is the resulting fireball from the world's second hydrogen bomb test: Operation Ivy's King shot. The mushroom cloud reached into the sky, and the dust barely settled, resulting in the disappearance of a pilot. This further supports the idea of the destructive nature of the thermonuclear bomb as well as potential to harm that it already demonstrated. Los Angeles Times (Los Angeles, CA). "H-BOMB TEST STORY MEETS AEC SILENCE." ​ November 9, 1952. The government kept the tests secret from the public, however information had already been leaked. Officials denied knowledge to the public. The military throughout the United States continually denied knowing anything about the nuclear bomb, causing even further stress upon the public. Memorandum of Conversation. July 6, 1954. ​ https://nsarchive2.gwu.edu/nukevault/ebb459/docs/doc%2012%20hot%20tuna.pdf. Reports of radiation poisoning in fish around the Castle Bravo detonation site were becoming increasingly common. This widespread effect further illustrates the dangerous 5 nature of thermonuclear development, and the environmental neglect that occurred by performing these tests.

This video shows the data and effects of the bombing of Bikini Atoll. Absolutely devastating, giant gusts of wind pushed out from the area as the US military stands by. It was incredibly powerful, and deliberate. The main thermal pulse of the low yield weapon completes in a few seconds. It takes 3 seconds to peak for the higher yield while it also maintained a longer duration. There was great intellectual progress. The New York Times (New York, NY). "EXPERIMENTS FOR HYDROGEN BOMB HELD ​ SUCCESSFULLY AT ENIWETOK; LEAKS ABOUT BLAST UNDER INQUIRY." November 12, 1952. People started suspecting that the hydrogen bomb went off, and more pressure from the public to know the status of the bomb as the Cold War went on caused frenzy as documentation and information that was leaked and later revealed. People were terrified about what was about to happen next, showing the social repercussions of the Cold War and the secretive nature of thermonuclear bombs. "Nuclear Testing Program In The Marshall Islands." July 19, 2005. Accessed September 2, 2019. http://large.stanford.edu/courses/2017/ph241/gutwald2/docs/S_Hrg_109-178.pdf. Operation Ivy and Operation Castle releases widespread radiation throughout the Pacific. The AEC went through with radiation monitoring in order to see the larger effects of the bomb. They later learned that it spanned all the way to Hawaii and Guam, as radiation levels were slightly elevated in those places. 6 Operation CASTLE. Defense Threat Reduction Agency, n.d.

Operation Ivy was the beginning to the rest of the thermonuclear bomb tests, such as Castle. Additionally, Operation Ivy led to the moving of test locations from Nevada to the Marshallese atolls. This was good for the background and transition from Operation Ivy to Operation Castle. Operation Castle. U.S. Department of Energy, 1954. https://archive.org/details/gov.doe.0800013. ​ This video documents the process of Operation Castle, and the explosion. This shows the deliberate actions taken to execute Operation Castle, yet the complete neglect for the Marshallese people. Operation IVY. 1952. https://archive.org/details/OperationIVY1952. ​ This video demonstrates the entire process in which Operation Ivy occured, from planning to the actual dropping of the bomb. It begins by talking about the upcoming test of the Mike bomb. It's too dangerous to test on land, so they choose to go to the Marshallese Islands. At the time manned machines were quite the force for the Army, Navy, and Air Force. Instead of utilizing experimental drones, manned jets were much more effective for the testing of nuclear bombs. In this case the Mike bomb was tested by these pilots creating cheaper methods of testing for the US. Operation Ivy: Mike Shot. AtomicHeritage, 2016.

    The Atomic Veterans' View Regarding VBDR, Dose Reconstruction and the V. A. Claim Compensation Programs By: R. J. Ritter – C.E.M. Director - National Commander National Association of Atomic Veterans, Inc. February 16, 2007 1. Slide N001 On behalf of America’s atomic veteran community, I am pleased to offer their views, issues, comments and suggestions to the Veteran’s Advisory Board on Dose Re-construction, the Defense Threat Reduction Agency, the Department of Veteran’s Affairs, and those interested parties who are with us today. When first asked to prepare this presentation, I found it impossible to adequately convey, those views, concerns and opinions in 30 short minutes. It is well to note that America’s atomic veterans have been attempting, for the last 50+ years, to tell the stories of their experiences to those who have little or no interest in these events. With this in mind, I have selected a series of slides from a ( 90 minute ) public awareness program developed by NAAV, Inc., that will address their core issues within the allotted 30 minute period. This approach will adequately convey the depth, magnitude and importance of those radiation exposure events that were a critical part of their life experiences, and bring to the forefront the root cause for our presence here today. Slide N002 The year 1945 marked the dawn of the age of nuclear weapons, as the Manhattan Project proof tested the world’s first atomic bomb, and the decision by United States to used these atomic weapons to shorten the war in the Pacific.

    © Copyright 2016 Michael R. Lehman NUISANCE TO NEMESIS: NUCLEAR FALLOUT AND INTELLIGENCE AS SECRETS, PROBLEMS, AND LIMITATIONS ON THE ARMS RACE, 1940-1964 BY MICHAEL R. LEHMAN DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in History in the Graduate College of the University of Illinois at Urbana-Champaign, 2016 Urbana, Illinois Doctoral Committee: Professor Lillian Hoddeson, Chair Professor Kristin Hoganson, Co-Chair Professor Michael Weissman Professor Robert Jacobs, Hiroshima City University Abstract Fallout sampling and other nuclear intelligence techniques were the most important sources of United States strategic intelligence in the early Cold War. Operated as the Atomic Energy Detection System by a covert Air Force unit known as AFOAT-1, the AEDS detected emissions and analyzed fallout from Soviet nuclear tests, as well as provided quantitative intelligence on the size of the Russian nuclear stockpile. Virtually unknown because the only greater Cold War secret than nuclear weapons was intelligence gathered about them, data on the Soviet threat produced by AFOAT-1 was an extraordinary influence on early National Intelligence Estimates, the rapid growth of the Strategic Air Command, and strategic war plans. Official guidance beginning with the first nuclear test in 1945 otherwise suggested fallout was an insignificant effect of nuclear weapons. Following AFOAT-1’s detection of Soviet testing in fall 1949 and against the cautions raised about the problematic nature of higher yield weapons by the General Advisory Committee, the Atomic Energy Commission’s top scientific advisers, President Harry Truman ordered the AEC to quickly build these extraordinarily powerful weapons, testing the first in secrecy in November 1952.

Buesseler Woods Hole Oceanographic Institution, Woods Hole, MA 02543, USA (Received 27 June 1996; accepted 15 August 1996) ABSTRACT Plutonium analyses of a dated coral record from the French Frigate Shoals in the central North Pacific indicate that there are two major sources of PM in this basin: close-in (troposphertc) fallout from nuclear weapons testing at the Pact& Proving Grounds in the Marshall Islands in the 1950s and global (stratospheric) fallout which peaked in 1962. Furthermore, the 240Pu/239Pu atom ratio of fallout ,from the Pacific Proving Grounds is characteristically higher (0.24) than that of global jhllout Pu (O.l8+I9). Seawater and sediment samples from the North Pacific exhibit a wide range of “40Pu/239Pu values (0.19-+34), with a trend towards higher ratios in the subsurface waters and sediment. Deep water 240Pul”39Pu ratios are higher in the vicinity of the Marshall Islands relative to stations further from this close-in fallout source. These preli- minary data suggest that fallout Pu from the Pacific Proving Grounds is more rapidly removed from the surface waters than is global fallout Pu. Plutonium geochemistry appears to be related to the physical/chemical form of PM-bearing particles generated by dtfferent ,fallout sources. (‘ 1997 Elsevier Science Limited. INTRODUCTION The input of fallout plutonium (Pu) from atmospheric nuclear weapons testing is the largest source of Pu to the environment, including the oceans (Harley, 1980; Perkins & Thomas, 1980).
