Description
A new theory is described for the uptake of U in an open system applied to the dating of archaeological bones. Analytical solutions are obtained for the rate of radioactive decay of238U,234U and230Th as a function of position for the case where both238U and234U diffuse across a bone, and where external supply of234U is not in equilibrium with238U. The new theory constitutes a forward model for predicting238U,234U and230Th activity profiles across a bone given an age and diffusion coefficient....[Show more]
