Geoquímica de radionuclídeos naturais em solos de áreas circunvizinhas a uma Unidade de Mineração e Atividade de Urânio

Abstract: RESUMOOs impactos ambientais advindos da exploração e do beneficiamento de U são, em grande parte, idênticos àqueles causados por atividades minero-extrativistas em geral. Este trabalho teve o objetivo de determinar a partição geoquímica dos radionuclídeos naturais 238

“…Comparing the range of values, the soils of São Paulo State (Hiromoto et al, 2007) reached lower values than those found in this survey, although our values are lower than those reported by the Brazilian HBRA of Poços de Caldas (Minas Gerais), Caetité (Bahia), the phosphate region of Pernambuco (Amaral and Mazzilli, 1997;Santos Júnior et al, 2006;Cardoso et al, 2009), and in the area rich in monazite sands in São Francisco de Itabapoana, also in Rio de Janeiro (Lauria et al, 1999). For 40 K, this study found higher values than those reported by Veiga et al (2006) for the sand beaches in the southern part of Rio de Janeiro and for São Paulo and Bahia.…”

“…In Brazil, surveys on the radioactivity in soil were conducted mainly in the areas with high natural background radiation (HBRA), as for example in Poços de Caldas, on the beaches of monazite sand in the Espírito Santo State (Franca, 1963;Roser et al, 1964), and in other specific and restricted areas (Amaral, 1992;Malanca et al, 1993;Amaral and Mazzilli, 1997;Lauria, 1999;Alencar and Freitas, 2005;Santos Júnior et al, 2006;Hiromoto et al, 2007;Umisedo, 2007;Cardoso et al, 2009;Lauria, 2009). However, large-scale systematic surveys on soil radioactivity are not available in Brazil and to date, QRVs for radionuclides were only established in two Brazilian states (Peres, 2007;Peixoto, 2013).…”
