Introduction [Soil–Plant Transfer of Radionuclides in Non-temperate Environments. Report of Working Group 4 Transfer Processes and Data for Radiological Impact Assessment Subgroup 3 on Non-temperate Data. IAEA Programme on Modelling and Data for Radiological Impact Assessments (MODARIA II)]

This publication covers radionuclide transfer in tropical and arid environments with a focus on root uptake by crops from soils. The data collected and analysed are relevant for estimating the transfer of radionuclides through food chains to humans and for assessing radiation doses to the public due to intakes of radionuclides in plant products used as food. The data relate to equilibrium conditions between the radionuclide's dynamics into and out of the compartments of the environment and are appropriate for REIA in planned and existing exposure situations where such conditions have been established. Moreover, this publication classifies the data according to an international climate classification scheme and compares the summary values derived for tropical and arid environments with those presented in TRS 472 for temperate environments.
