The flux database concerted action

The background to the IUR action on the development of a flux database for radionuclide transfer in soil-plant systems is summarised. The action is discussed in terms of the objectives, the deliverables and the progress achieved by the Aux database working group. The paper describes the background to the current initiative, `outlines specific features of the database and supporting documentation, and presents findings from the working group's activities. The aim of the IUR flux database working group is to bring together researchers td collate data from current experimental studies investigating aspects of radionuclide transfer in soil-plant systems. The database will incorporate parameters describing the time-dependent transfer of radionuclides between soil, plant and animal compartments. Work under the EC Concerted Action considers soil-plant interactions. This initiative has become known as the radionuclide flux database. It is emphasised that the word Aux is used in this case simply to indicate the flow of radionuclides between compartments in time.
