Levantamento dos níveis de radioatividade natural em águas do alto Vale do Ribeira à planície costeira do litoral sul do Estado de São Paulo

Abstract

The complex exchange of fluvial, subsurface and seawater within a coastal area directly affects global biogeochemical cycles and the application of isotopic tracers, mainly natural radionuclides from U and Th series, is a powerful tool to track sources and sinks of trace elements and nutrients to this systems. The unique Ra signature applied to quantify the
