摘要
A marine sediment core from the Kattegat area (Sweden) has been studied for dating purposes. The Cs-137 and Pb-210 profiles have been measured and described by a model of incomplete activity mixing. A time-dependent CS-137 flux function for the sediment has been constructed from atmospheric data and the Cs-137 contents in water from the Sellafield nuclear reprocessing plant. It has been used as the Cs-137 input function for our model. The results show that the model clearly reproduces the measured profile.
