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)

This paper examines the US Atomic Energy Commission’s radioisotope distribution program, established in 1946, which employed the uranium piles built for the wartime bomb project to produce specific radioisotopes for use in scientific investigation and medical therapy. As soon as the program was announced, requests from researchers began pouring into the Commission’s office. During the first year of the program alone over 1000 radioisotope shipments were sent out. The numerous requests that came from scientists outside the United States, however, sparked (...) a political debate about whether the Commission should or even could export radioisotopes. This controversy manifested the tension between the aims of the Marshall Plan and growing US national security concerns after World War II. Proponents of international circulation of radioisotopes emphasized the political and scientific value of collaborating with European scientists, especially biomedical researchers. In the end, radioisotopes were shipped from the Commission’s Oak Ridge facility to many laboratories in England and continental Europe, where they were used in biochemical research on animals, plants, and microbes. However, the issue of radioisotope export continued to draw political fire in the United States, even after the establishment of national atomic energy facilities elsewhere. (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 Isotope School was established in 1951 by the British Atomic Energy Research Establishment at Harwell following the model of the American Oak Ridge Institute of Nuclear Studies. Until its dissolution in 1967, it played an important role in the expansion of radioisotope techniques in Britain and Western Europe. This paper traces the origin and activities of the Isotope School, and describes the content of its courses and the composition of its audiences both in Britain and abroad. These illustrate the (...) motivations behind the early diffusion of nuclear technology and the importance of Cold War politics in shaping the flows of materials and expertise. In particular, the ban on attendance of Eastern European students at the courses reveals a persistent tension inside the British nuclear programme: the conflict between the drive for disseminating nucleonics and the restrictions forced by national security concerns.
