SUMMARY Low‐level nuclear counting has been carried out on sediment cores from Lake Bouchet in France and from the Black Sea. The cores span the past 20 Ka. The variation of α and β particle counting rates with core depth, i.e. with time, shows features which can reasonably be associated with climatic change. The discussion is augmented by some high resolution γ ray spectrometry measurements of the specific activity of particular component radionuclides ( 214 Pb, 212 Pb and 40 K) in the Black Sea cores.
