BIOPROTA is an international collaboration forum which seeks to provide a transparent and traceable basis for the choices of parameter values, as well as for the wider interpretation of information used in assessments. Particular emphasis is placed on data required for the assessment of long-lived radionuclide migration and accumulation in the biosphere, and the associated radiological impact, following discharge to the environment or release from solid waste disposal facilities.
This study was supported financially by the following sponsoring organisations: Agence Nationale pour la Gestion des Déchets Radioactifs (Andra,France), Electricité de France (EDF, France), LLW Repository Ltd (LLWR, UK), the National Cooperative for the Disposal of Radioactive Waste (Nagra, Switzerland), the Nuclear Decommissioning Authority Radioactive Waste Management Directorate (NDA RWMD, UK), Nuclear Waste Management Organisation of Japan (NUMO, Japan), Svensk Kärnbränslehantering AB (SKB, Sweden) and Strålsäkerhetsmyndigheten (SSM, Sweden).
This report provides a summary of a programme of work, commissioned within the BIOPROTA collaborative forum, to compare and contrast different assessment models for the behaviour of C-14 in soil and plants.
