Fig. 2 represents the TL glow curve of one sample (A-4) from Tell Al-Shekdakah site. Based on the plateau test the ED was measured by integration the TL curves
between 290°C and 330°C,
Fig. 3 represents the growth curve for the same sample above. As it is known the
intercept with the dose = 0 axis (X-axis) gives the absorbed dose.
Before using the obtained ED on Eq. 1.1 it must have been corrected for the supralinearity (I), where the new palaeodose value (P) is P = ED + I.
The supralinearity correction was determined using the same disks which were used for measuring natural TL,
a regeneration growth curve was constructed using TL signals measured after the irradiation with four small different known doses (see Fig. 3 as an example).
We noticed from this figure that the supraliniarity correction for the sample A-4 is 0.6 Gy.
The final archaeological dose for the samples analyzed, after taking into account the supraliniarity correction, are presented in Table 1.7).
