Above all, this study seeks information that may be useful to improve our understanding of the relationships between natural radionuclides in soils and environmental characteristics.  aPotassium  aRadium  aSoil  aPotássio  aRádio  aSolo  aNatural radionuclides  aRadioactivity mapping  aValores de referência de qualidade1 aSILVA, J.
