The photographers' gaze: the Mobile Radioisotope Exhibition in Latin America (1960-1965).

During the IAEA's Mobile Radioisotope Exhibition (1960-1965) through the eventful roads of five Latin American countries (Mexico, Uruguay, Argentina, Brazil, and Bolivia), a variety of photographs were taken by an unknown Mexican official photographer, and by Josef Obermayer, a staff driver from Vienna. The exhibition carried not only bits of nuclear sciences and technologies, but also the political symbolism of the 'friendly atom' as a token of modernization. The photographs embarked on different trajectories, though all of them ended up at the training and exchange official's desk in charge of the exhibition, Argentinian physicist Arturo Cairo. The ones taken in Mexico also had a local circulation as propaganda intended to promote radioisotope applications. The two sets of images were intended to show the contrast between modernity and traditional society, but they did it from different gazes. Our paper argues that, in the case of Mexico, the photographer reinforced representations of the country which were already popularized by Hollywood for foreign and local audiences. On the other hand, the Viennese photographer's gaze delivers an autoethnography of his dutiful journey. We also argue that Obermayer's projection is one of what Roger Bartra has conceptualized as the 'salvage on the mirror'.

Clouds, airplanes, trucks and people: carrying radioisotopes to and across Mexico.

The aim of this paper is to describe the early stages of Mexican nuclearization that took place in contact with radioisotopes. This history requires a multilayered narrative with an emphasis in North-South asymmetric relations, and in the value of education and training in the creation of international asymmetrical networks. Radioisotopes were involved in exchanges with the United States since the late 1940s, but also with Canada. We also describe the context of implementation of Eisenhower's Atoms for Peace initiative in Mexico that opened the door to training programs at both the Comisión Nacional de Energía Nuclear and the Universidad Nacional Autónoma de México. Radioisotopes became the best example of the peaceful applications of atomic energy, and as such they fitted the Mexican nuclearization process that was and still is defined by its commitment to pacifism. In 1955 Mexico became one of the 16 members of the atomic fallout network established by the United Nations. As part of this network, the first generation of Mexican (women) radio-chemists was trained. By the end of the 1960s, radioisotopes and biological markers were being produced in a research reactor, prepared and distributed by the CNEN within Mexico. We end up this paper with a brief reflection on North-South nuclear exchanges and the particularities of the Mexican case.
