| Miêu tả: | The present investigation reviews the different datation models and their connection to the sedimentation process of 210Pb in soils. The objective is to create a generalizable model capable to add different initial conditions of soil formation. We use the Least Square Fitting Method to predict a radiochronological scale profile obtained through gamma spectroscopy. With soil samples of Reserva Alberto Manuel Brenes, we obtained the chronostratigraphic profile with the highest 137Cs peak at 53 ± 9 years, coinciding with the 1963 atmosphere nuclear weapon test. The formation model that best fits the data is the Constant Initial Concentration model. |
