Description

A geochronological study of the Guanabara Bay (RJ, Brazil) based on 210 Pb dating technique using the Constant Rate of Supply Model CRS is presented. A low energy gamma spectrometry (<100 KeV) was used for direct measurement of 210 Pb for samples collected from Estrela and Sao Joao de Meriti rivers. Radiochemical method was applied to determine the amount of 210 Pb in samples from Guapimirim, Guaxindiba and Imbuacu rivers. Atomic absorption spectrometry with air-acetylene flame technique was used to determine the amount of copper in all the samples. The CRS model showed adequate in this estuarine system.
