The Doomsday Clock is an internationally recognized design that conveys how close we are to destroying our civilization with dangerous technologies of our own making. First and foremost among these are nuclear weapons, but the dangers include climate-changing technologies, emerging... Read More
Pablo Cristini is manager of radioisotope production at Argentina's National Commission of Atomic Energy. While at the commission, he has led the process of converting production of molybdenum 99 from highly-enriched uranium to low-enriched uranium (LEU), and has overseen transfers of LEU-based technology for molybdenum production to national authorities in Australia and Egypt. Before becoming manager of radioisotope production, he was head of the commission's fission molybdenum production plant. He has published over 25 scientific papers. He received a degree in chemical sciences, with a specialization in radiochemistry, from the University of Buenos Aires in 1985.
The author argues that new facilities for fission radioisotope production should use low-enriched uranium targets from the very beginning, even if locally produced highly enriched uranium is available.
The author discusses the Argentine experience of conversion from highly enriched to low-enriched uranium for the production of medical radioisotopes, which has often been presented internationally as evidence that conversion is technically and economically feasible.
