TL ages of 1.93 ± 0.13 ka and 2.20 ± 0.19 ka have been also obtained from the baked soil samples with a plateau between 300 and 350°C.

As a dating tool the TL technique has been of great success in authentication of ancient ceramic art objects.

The samples were prepared by fine grain technique and the annual dose for each sample (pottery sherds and soil sample) was measured using an alpha spectrometer system for uranium and thorium contribution as well as with atomic absorption spectrometry for the potassium contents.

The mean ages were found to be 5500 ± 150 years, 2950 ± 50 years, 1200 ± 50 years, 1300 ± 150 years, 3300 ± 100 years and 3400 ± 200 years for the examined pottery from the sites Al-Shermanieh, Tell Serah, Der Al-Hajar, Tell Al-Shekdakah, Tell Al-Souwirieh and Khurbet Al-Kulieh, respectively.

This enables us to calculate the approximate age of the piece.

Using TL we can see that one of these ‘fat ladies’ is genuine and the other is a modern copy.

Sample discs are mounted on a wheel and the readers are programmed to run heating and irradiation sequences.
