Abstract

In this work, we show the preliminary results on the 137Cs dating of the tidal flood sediments in the barrier-island system of Aveiro (Portugal). The ”7Cs activity enable us to establish four isochrones which limit the last four decades, through the correlation of historical data of137Cs atmospheric concentration. The sediment acumulation rates on the intertidal flat is calculated to be 0.6 cm yr1
