In (a) the OSL signal from a single multi-grain disc of sample AS107-4 (core site VII) is shown. The calculated De of 3.47 ± 0.16 Gy is indicated by the dotted line on the dose response curve. In (b) the OSL signal from a single grain of sample AS87-3 (core site IV) (De 6.17 ± 0.66 Gy) and the dose response curve are shown. Uncertainties have been calculated by combining and propagating in quadrature systematic and random sources of uncertainty.
