Assessment of environmental impact models in natural occurring radionuclides solid wastes disposal from the mineral industry; Avaliacao de modelos de impacto ambiental para deposicao de residuos solidos com radionuclideos naturais em instalacoes minero-industriais

Abstract

This work evaluates the behavior of wastes with naturally occurring radionuclides as generated by the mineral industry and their final disposal in landfills. An integrated methodology is used to predict the performance of an industrial landfill for disposal of wastes containing NORM/TENORM, and to define acceptable amounts that can be disposed at the landfill using long-term environmental assessment. The governing equations for radionuclide transport are solved analytically using the generalized integral transform technique. Results obtained for each compartment of the biogeosphere are validated with experimental results or compared to other classes of solutions. An impact analysis is performed in order to define the potential consequences of a landfill to the environment, considering not only the engineering characteristics of the waste deposit but also the exposure pathways and plausible scenarios in which the contaminants could migrate and reach the environment and the human population. The present work permits the development of a safety approach that can be used to derive quantitative waste acceptance criteria for the disposal of NORM/TENORM waste in landfills. (author)
