The Third International Conference on Isotopes focused on the theme of “Isotope Production and Applications in the 21st Century” and included presentations by several eminent experts in this field. The three central subjects — Isotopes in Medicine, Industry and the Environment — were supplemented by presentations on the latest developments in isotope production and synthesis, research into radiopharmaceuticals, applications in agriculture, analytical applications, radiocarbon dating, AMS and PET. Various views on the future directions for producers and users of isotopes were considered at this multi-disciplinary meeting.Contents:Isotope Facilities and ProgramsRadiochemical Synthesis I–II, Nuclear Analytical Applications of Radioisotopes I–IIRadioisotope ProductionSeparation and Applications of Stable IsotopesIndustrial Applications and Radiation SafetyRadiopharmaceutical Applications and Medical Imaging I–IIProduction and Applications of Isotope Tracers in Industry I–IIUse of Isotopes in Environmental Studies I–IIApplications of Isotopes in Medical Imaging and TherapyRadiation Safety Aspects at Isotope FacilitiesApplications in Agriculture and NutritionAMS and Radiocarbon Dating TechniquesPoster SessionApplications of Isotopes in Environmental StudiesProduction and Applications of Short-Lived RadioisotopesLabeling Compounds and Other Applications of TritiumNovel Applications of Isotopes and Opportunities for Technology TransferClosing Plenary Session: “Isotope Production and Applications in the 21st Century”Readership: Radiochemists, radiopharmacists, environmental scientists, reactor and accelerator physicists, and nuclear medicine researchers.Key Features:Reviews new and renewable energy sourcesDiscusses the latest developments in bioengineering for energy generationIncludes a discussion of greenhouse gas emissionConsiders a sustainability development in practice
