Isotope networks: Training, sales and publications, 1946-1965

The aim of this paper is to provide an assessment of the spread of isotope-related techniques in Western Europe and the USA in the two first decades after World War II, by focusing on structural features. In particular, I analyse three major components of the European "isotope industry": radioisotope distribution networks, the establishment of training sites and publications in which isotopes played some role as the object of study or research tools. This study leads to an assessment of the importance of industrial applications of isotopes in this period, in relation to biomedical ones, and provides with a transnational comparison in terms of productivity in material resources, workforce and knowledge.
