Figure 2

Typical dose response curves for sample EMB400 for quartz (OSL), together with a typical decay curve (insets) Response curves were best fitted to a single saturating exponential. The dotted line presents a simple example of equivalent dose determination for one aliquot where Lx/Tx = 1.95 and D = 9.66 Gy.
