Radioactive and stable isotopes are used throughout the world and in many sectors, including medicine, industry, agriculture and research. In many applications isotopes have no substitute, and in most others they are more effective and cheaper than alternative techniques or processes. This publication is the first international survey on the beneficial uses and production of isotopes. It provides an overview of their main uses, and detailed information on the facilities that produce them world-wide. Trends in isotope supply and demand are analysed, and the conclusions and recommendations presented point to key issues to be considered by governments.

It has been widely recognised among researchers that speciation data are essential for proper and reliable modelling of radionuclide behaviour, which is studied inter alia in the context of radioactive waste management. Participants at the OECD/NEA workshop on "Evaluation of Speciation Technology" reviewed the various techniques used to identify different species of actinide and fission product elements present in nuclear waste and nuclear reprocessing streams. The review takes into account the advantages, disadvantages and limitations of the various methods in relation to their field of application. Recommendations for future R&D are also provided. These proceedings will primarily be of interest to chemists specialised in separation techniques and radioactive waste management experts.

GEOTRAP is the OECD/NEA Project on Radionuclide Migration in Geologic, Heterogeneous Media carried out in the context of site evaluation and safety assessment of deep repository systems for long-lived radioactive waste. Retention of radionuclides within the geosphere for prolonged periods is an important safety function of deep geologic disposal concepts for radioactive waste. The extent to which retention processes can be relied upon in repository performance assessment depends upon the existence of well-established theoretical bases for the processes. It also depends on support for the operation of specific retention processes, and models for their quantitative evaluation, from a wide range of laboratory and field experiments and observations from nature. The fifth GEOTRAP workshop, "Geological Evidence and Theoretical Bases for Radionuclide-retention Processes in Heterogeneous Media" held in May 2001, looked at radionuclide-retention processes and their consideration and representation in performance assessments. Current approaches to characterising and modelling retention processes, and suggestions for future improvements, were presented and discussed. In addition to the material presented during the workshop, this publication includes a technical synthesis reflecting the discussions that took place as well as the conclusions and recommendations made, notably during the working group sessions.
