WebRadionuclide dating is a robust technique for establishing the recent accumulation rate for most peatlands. In this article we review the production of ‘fall-out’ radionuclides and the concepts underlying the dating method. Some inherent problems such as the issues surrounding reduced natural radionuclide deposition, e.g. ‘continentality’, are highlighted. … WebJun 1, 1995 · The paper summarizes and evaluates the results of 210 Pb, 137 Cs and 241 Am analysis on 37 recent ombrotrophic peat profiles. From these and previously published data, it is concluded that radiometric measurements alone cannot be relied on to give an accurate chronology of peat accumulation.

The same can be said for each peat layer in a peat deposit. 14C dating of wood, char- coal or peat in autochthonous position provides a close "true age" for the context with which the sam- ple is associated.3 Most samples dated in this study conform to these conditions and, consequently,
WebAMS can precisely date individual points in recent peat deposits within the range of the bomb-pulse (from the mid-1950s on). Comparing the 14C AMS results with the customary dating method for recent peat profiles by 210Pb, we show that the use of 137Cs to validate and correct 210Pb dates proves to be more problematic than previously supposed.
