dc.description.abstract	210Pb concentration in marine sediments of the Cariaco Trench (North‐East of Venezuela) was measured through the analysis of 210Po alpha emissions, which can be assumed to be in secular equilibrium with 210Pb. The analysed sediment core has a length of 1.9 m. The results allowed to apply the CF:CS dating model (Constant Flux and Constant Supply). The sedimentation rate was estimated to be 0.25 cm/y. As far as we know this is the first α‐ dating carried out in the country, performed with an alpha spectrometer recently funded by the IAEA.	es
