Abstract

Lake sediment cores were extracted from Lake Auburn, in Maine, USA and Patagonia, Bariloche, Argentina. The cores were counted in a High-Purity Germanium Well Detector and measured for different radioisotopes, specifically 210Pb and 137Cs. The mathematical model implemented for analyzing the data is a combination of the Constant Rate of Supply (CRS) and the Constant Initial Concentration (CIC) models. The data was utilized to calculate the age of the sediment and the cores from the two different locations are compared and contrasted in this thesis.
