ESR dating of tooth enamel: Coupled correction for U-uptake and U-series disequilibrium

ESR dates on tooth enamel require a knowledge of the history of uptake of uranium (U) by both the dentin and enamel. We present a method of determining the uptake history by simultaneously fitting a model uptake function to the U-series and accumulated dose data. The function is of the form U(t) = Uo(t)p+1; Uo is the observed U-238 content of the tooth; p is a parameter to be determined in the fitting procedure; T is the age of the sample, and U(t) is the U content at any time t.
