Radionuclide mapping of the Molise region (Central Italy) via gamma-ray spectrometry of soil samples: relationship with geological and pedological parameters

Baseline and Quality Reference Values for Natural Radionuclides in Soils of Rio de Janeiro State, Brazil

“…Radiological surveys were carried out in many countries to determine the natural content or background contents of radionuclides in soils (Saleh et al, 2007;Laubenstein et al, 2013;Ugur et al, 2013;Garba et al, 2015;Pillai et al, 2016). 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).…”
