Modelling radionuclide transport in the environment and calculating radiation doses

Abstract: Herein, consideration is first given to how radionuclides from various natural and anthropogenic sources disperse through the environment and are taken up by biota. The aim of the discussion on dispersion is to show how the transport of radionuclides released to the environment, whether in the short term or long term, can be modelled so as to estimate concentrations of those radionuclides in environmental media such as soils, sediments and water bodies. Subsequent sections describe how radiation doses to humans and non-human biota from radionuclides present in the environment are calculated, and describe some tools that are helpful in achieving comprehensiveness of assessment. Finally, some current developments and trends in modelling radionuclide migration in the biosphere are briefly discussed.
