Nondestructive activation analysis of ancient pottery by 14 MeV neutrons
- 26 Downloads
The use of 14 MeV neutrons for the analysis of ancient pottery was investigated. Clay pieces from Arezzo and Northern Italy were quantitatively analysed in a completely nondestructive way. A comparison technique using Al-foils as a standard was introduced. The main components Si, Al, Mg and Fe could be evaluated within a short time with an error of a few percent. The grouping resulting from impressed seals on the clay pieces was in full agreement with that resulting from the chemical composition for the potsherds from Arezzo. An analysis of trace elements was also performed for a few samples, but it needs more time for irradiation and measurements.
