Abstract

The study of sedimentation rates and age of marine sediments has been performed through many years using natural and artificial radioactive isotopes. Polluted sediments were collected in three sampling points in the Havana Bay. Sedimentation rates were estimated using two different radiometric approaches: the depth profiles of 137Cs and 210Pb. The maximum activity 137Cs might indicate the proximity of the 1964's. The unsupported 210Pb has been measured to apply both the Constant Initial Concentration Method (CIC) and the Constant Rate of Supply Method (CRS) Dating Models. The results show values for sedimentation rate ranging from 0.2 up to 1.3 cm.y-1 increasing with time which manifests the importance of the achievement of a project of dredging.
