Tests of the top few cm and of surficial sediment indicate that the Po and Pb concentrations are quite similar.
sediment lithology) may be needed to establish a reliable chronology.
A sediment core taken from a tidal mudflat in Ho Bugt in the northernmost part of the Wadden Sea in Denmark is used to explore the application of optically stimulated luminescence (OSL) dating to young fine-grained estuarine sediments, using Cs Sellafield peak from 1980 as independent age control.
Pb in soils and sediments involved laborious and time-consuming radiochemical separation procedures.
Due to the recent development of advanced planar (‘n-type’) semi-conductors with high efficiencies in the low-energy range which enable the gamma-spectrometric analysis of the 46.5 ke V decay line of Cs shows that the information which may be gained by these two tracers is complementary.
Many people in this latter category affirm the intimate involvement of God in this process of creation.
