Towards a new chronostratigraphic method based on the marine sediment radioactivity variation

Sediment radioactivity (alpha and beta particle counting) from six cores fr om the Aegean and Ionian seas shows apparent variation identified with cert ain palaeoclimatic features during the Holocene and the last glaciation. Th e discussion of the radioactivity variation, the dating of the cores, the e stimated sedimentation rates, and the palaeoclimatic recognition, is corrob orated by the geotechnical properties of the sediments, some AMS C-14 dates , core intercomparison, and correlations with proxy climatic data.
