Aging Environmental Samples Using 210Pb

MyCore Scientific Inc. provides Paleodating services. We specialize in the analysis and interpretation of sediment accumulation rates and the age of sediment stratigraphies. Clients use sediment ages to examine the impact of historical events in land or water usage to changes within the aquatic environment.

210Pb is an isotope in the uranium-238 decay series. It occurs naturally throughout the biosphere. Although it can occur in secular equilibrium with its grandparent, 210Pb concentrations are not constant because geo-chemical processes separate 210Pb from the longer lived parent isotopes in many systems. This separation and subsequent decay provides the opportunity for the use of 210Pb as a dating tool.
