    Factors controlling mobility of radionuclides in tropical soils and groundwaters
    (Australian Nuclear Science and Technology Organisation, 2012-10-18) Payne, TE; Edis, R; Twining, JR
    Due to the possible expansion of nuclear power into equatorial regions, there is an imperative to better understand the mobility of radionuclides in the tropics. The migration of radionuclides in tropical soils and groundwaters is subject to the same basic scientific principles as many other environments. However, the behaviour of radionuclides is also modified by many unique features of tropical systems, including: climate and rainfall characteristics, soil mineralogy and properties, content and cycling of organic matter, specific land-use practices and the presence of unique, potentially impacted environments (for example, coral atolls in the case of weapons tests). Many tropical environments involve combinations of climatic and geochemical conditions not experienced elsewhere, and are also subject to environmental modifications including urbanisation and climate change. These characteristics will influence the impact of potential radionuclide releases in the tropics. An increased focus of scientific research is required to enhance knowledge on this topic.
