On September 23, 1949, President Harry Truman announced that the Soviet Union had successfully detonated an atomic bomb. The news that the Soviet Union had done this came as little surprise to a number of American scientists and to some members of the intelligence community who had predicted that the Soviets would quickly acquire this advanced weapons technology. But for many Americans this news was disturbing. Truman’s announcement was taken up by, among others, a young Baptist evangelist named Billy Graham. (...) Opening a tent revival in Los Angeles just two days after the President’s report, Graham preached how the news of the Soviet bomb test had “startled the world” and launched an “arms race unprecedented in the history of the world.” President Truman, he informed his listeners, said that we “must be prepared for any eventuality at any hour….” Perhaps even more ominously he asked the crowd, “Do you know the area that is marked out for the enemy’s first atomic bomb? New York! Secondly, Chicago; and thirdly, the city of Los Angeles!” It was not only evangelical preachers who foresaw catastrophic implications from a growing arsenal of atomic weapons. (shrink)

A political discourse of peace marked the distribution and use of radioisotopes in biomedical research and in medical diagnosis and therapy in the post-World War II period. This occurred during the era of expansion and strengthening of the United States' influence on the promotion of sciences and technologies in Europe as a collaborative effort, initially encouraged by the policies and budgetary distribution of the Marshall Plan. This article follows the importation of radioisotopes by two Spanish research groups, one in experimental (...) endocrinology and one in molecular biology. For both groups foreign funds were instrumental in the early establishment of their laboratories. The combination of funding and access to previously scarce radioisotopes helped position these groups at the forefront of research in Spain. (shrink)

Hibakusha are “witnesses” of the atomic bombings, not just in a standard sense but also in the instrumental sense. For medical and scientific experts, hibakusha are biological resources of unparalleled scientific value. Over the past seventy years, the hibakusha bodies have narrated what it means to be exposed to radiation. In this paper, I explore studies at the Atomic Bomb Casualty Commission that examined hibakusha bodies as sites where risk could be read. I focus on a period from the mid-1950s (...) to 1975, during which new methods, practices, and technologies allowed ABCC scientists to investigate chromosomes as a way to study radiation exposure and human risk. By focusing on chromosomal aberrations, ABCC scientists connected their work directly to the emerging infrastructure for radiobiology at the time. ABCC administrators actively sought out such prestige, especially given their relationship with the Atomic Energy Commission. The shift in approach would also alleviate some public relations problems with which the institution was struggling. Launching a cytogenetics program required some older practices that had assumed American privilege and dominance to be abandoned. Eventually, the decision to let chromosomes speak of radiation exposure brought about fundamental changes in ABCC, which came to symbolize the model for future studies at the organization, especially as ABCC was transitioning to a US-Japan binational organization. More broadly, this case highlights the intricate scientific negotiation of radiation risk where uncertainties necessarily prevail. (shrink)

The 1979 partial nuclear reactor meltdown at Three Mile Island was simultaneously hyper-visible and hidden from public view. It was the subject of non-stop media attention, but its causes and consequences required expert explanation. No fire or explosion marked the moment when insensible radionuclides escaped the facility. Yet, residents recalled a variety of troubling sights, sounds, odors, tastes, and sensations. Public distrust percolated in the interstices between government assertions that little radiation had escaped the facility and residents’ sense memories of (...) the incident. This article traces intertwined networks of activists from Japan and Pennsylvania as they mobilized legally, politically, and scientifically to develop evidence about the offsite effects of Three Mile Island. Exploring the distinct cosmology of evidence that activists marshaled, the article shows how they placed the messy, contingent, dynamic living world at the center of inquiries about the meltdown’s consequences. Activists developed new practices of biological witness that reconfigured the interplay between scientific, legal, and moral authority, while concurrently reformulating sufferers’ subjectivities and notions of scientific objectivity. In the process, they suggested that environmental justice entailed epistemic justice. Their cosmology of evidence served as an argument and a material proof that the beloved but suffering living world, and the sciences used to understand it, could and should frame the governance of industrial society’s invisible harms.

This paper extends previous arguments against the assumption that the study of variation at the molecular level was instigated with a view to solving an internal conflict between the balance and classical schools of population genetics. It does so by focusing on the intersection of basic research in protein chemistry and the molecular approach to disease with the enactment of global health campaigns during the Cold War period. The paper connects advances in research on protein structure and function as reflected (...) in Christian Anfinsen’s The molecular basis of evolution, with a political reading of Emilé Zuckerkandl and Linus Pauling’s identification of molecular disease and evolution. Beyond atomic fallout, these advances constituted a rationale for the promotion of genetic surveys of human populations in the Third World, in connection with international health programs. Light is shed not only on the experimental roots of the molecular challenge but on the broader geopolitical context where the rising role of biomedicine and public health had an impact on evolutionary biology.

This essay introduces a special collection of papers by Angela Creager, Soraya de Chadarevian, Karen Rader, Jean-Paul Gaudillière, and María Jesús Santesmases on the theme "Radiobiology in the Atomic Age.".

In 1962 a team of scientists conducted their first joint fieldwork in a Xavante village in Central Brazil. Recycling long-standing notions that living Indigenous people represented human prehistory, the scientists saw Indigenous people as useful subjects of study not only due to their closeness to nature, but also due to their sociocultural and political realities. The geneticists’ vision crystalized around one subject – the famous chief Apöwẽ. Through Apöwẽ, the geneticists fixated on what they perceived as the political prowess, impressive (...) physique, and masculine reproductive aptitude of Xavante men. These constructions of charismatic masculinity came at the expense of recognizing how profoundly colonial expansion into Mato Grosso had destabilized Xavante communities, stripping them of their land and introducing epidemic disease. The geneticists’ theorizing prefigured debates to come in sociobiology, and set up an enduring research programme that Apöwẽ continues to animate even four decades after his death. (shrink)

United States Air Force planes fly across mountains of green forest; behind them, fine white streams of chemical spray fill the sky. The planes fly alone or in formation covering wide swaths of the entire landscape. These images of the herbicide spraying during the United States-Vietnam War are ubiquitous in media material about Agent Orange, the most heavily used of the fifteen herbicides sprayed during the war. This representation of the war does not include guns, grenades, tanks, bombs, or dead (...) bodies. Instead, contemporary documentary filmmakers offer images of airplanes and chemical barrels to provide evidence of another weapon of war, pan dead and leafless forests in an otherwise lush landscape of green, and zero in on children’s deformed bodies to show the lasting environmental and health effects of Agent Orange. In this essay I share preliminary thoughts from my new project on Agent Orange and film in the United States and Vietnam. The bulk of social science writing on Agent Orange has focused on American veterans and their fight to secure benefits, while film scholars have analyzed the Vietnam War in Hollywood movies and television. I investigate documentary film, the transnational activism that generates these films, and the representations of gender, disabilities, bodies, history and culture within them. Here I offer a close reading of two turn-of-the-twenty-first-century documentaries about Agent Orange in Vietnam. (shrink)

Experimental radiobiology represented a long-standing priority for the U.S. Atomic Energy Commission, but organizational issues initially impeded the laboratory progress of this government-funded work: who would direct such interdisciplinary investigations and how? And should the AEC support basic research or only mission-oriented projects? Alexander Hollaender's vision for biology in the post-war world guided AEC initiatives at Oak Ridge, where he created and presided over the Division of Biology for nearly two decades. Hollaender's scheme, at once entrepreneurial and system-oriented, made good (...) use of the unique resources provided by the AEC and by Oak Ridge's national laboratory setting, while at the same time it restructured wartime research practices to better reflect biologists' own priorities. Because Hollaender offered many academic experimental biologists a way of envisioning military-related patronage as integral - rather than antithetical - to their professional identities, his work provides an important lens through which to examine the early post-war intellectual and institutional development of radiobiology.

The National Academy of Science's 1956 study on the Biological Effects of Atomic Radiation was designed to provide an objective analysis to assess conflicting statements by leading geneticists and by officials in the Atomic Energy Commission. Largely because of its status as a detached, non-governmental evaluation by eminent scientists, no studies have had a broader impact on the development of biological thinking in regard to nuclear policies. This paper demonstrates that despite the first BEAR study's reputation as an objective and (...) independent study, it was the product of careful negotiation between Academy scientists, the Atomic Energy Commission, and Britain's Medical Research Council. This paper also reveals the fragility of the consensus that produced the Academy's report, the range of political uses of the report, and the subsequent disaffection of the scientists who took part in it.

The widespread adoption of radioisotopes as tools in biomedical research and therapy became one of the major consequences of the "physicists' war" for postwar life science. Scientists in the Manhattan Project, as part of their efforts to advocate for civilian uses of atomic energy after the war, proposed using infrastructure from the wartime bomb project to develop a government-run radioisotope distribution program. After the Atomic Energy Bill was passed and before the Atomic Energy Commission was formally established, the Manhattan Project (...) began shipping isotopes from Oak Ridge. Scientists and physicians put these reactor-produced isotopes to many of the same uses that had been pioneered with cyclotron-generated radioisotopes in the 1930s and early 1940s. The majority of early AEC shipments were radioiodine and radiophosphorus, employed to evaluate thyroid function, diagnose medical disorders, and irradiate tumors. Both researchers and politicians lauded radioisotopes publicly for their potential in curing diseases, particularly cancer. However, isotopes proved less successful than anticipated in treating cancer and more successful in medical diagnostics. On the research side, reactor-generated radioisotopes equipped biologists with new tools to trace molecular transformations from metabolic pathways to ecosystems. The U.S. government's production and promotion of isotopes stimulated their consumption by scientists and physicians, such that in the postwar period isotopes became routine elements of laboratory and clinical use. In the early postwar years, radioisotopes signified the government's commitment to harness the atom for peace, particularly through contributions to biology, medicine, and agriculture. (shrink)

What Is Race? Evidence from Scientists (1952) is a picture book for schoolchildren published by UNESCO as part of its high-profile campaign on race. The 87-page, oblong, soft-cover booklet contains bold, semi-abstract, pared-down images accompanied by text, devised (so it declared) to make scientific concepts ‘more easily intelligible to the layman’. Produced by UNESCO’s Department of Mass Communication, the picture book represents the organization’s early-postwar confidence in the power of scientific knowledge as a social remedy and diplomatic tool. In keeping (...) with a significant component of the race campaign, What Is Race? presented genetics as the route to an enlightened, scientific, non-prejudiced understanding of race. This article seeks to explain the book’s management, aesthetics and framing in the context of postwar disciplinary and international politics. Viewing UNESCO’s race campaign as a high point for an internationalist ideology of mass education, this article also analyses the visual and literary arguments of What Is Race? and proposes that the enduring image of genetics as technical and neutral knowledge was in part shaped by UNESCO’s efforts to communicate scientific authority to an apparently ‘popular’ audience.
