摘要：

A method for dating sediment core layers from the Var riverbed was developed. The signature of the Chernobyl event was detected in the layer sequence by gamma-ray spectrometry of (137)Cs and correlated to the flow amplitude from the historical records. The residence time of groundwater in the aquifer of the lower Var valley was determined by measuring activity ratios of radium isotopes in well water samples. To cite this article: V.
