Natural gamma radiation measurements of coastal sand deposits were used to determine the provenance of the sandy sediments and to obtain information about paleo-sea-levels along the coast of three Brazilian States: Sao Paulo (SP), Rio de Janeiro (RJ) and Espirito Santo (ES). Th/U and Th/K ratios suggest a considerable positive correlation with the geological evolution of the Quaternary coastal deposits of the Brazilian Southeast.
