Analysis by neutron activation analysis a some ancient ceramics from Romanian territories

In this paper we have analyzed samples of Neolithic ceramics from Cucuteni-Scanteia - Vaslui county and Neolithic and Dacian ceramics from Magurele - Bucharest, by the method of neutron activation analysis. The following elements have been observed: Fe, K, La, Mn, Na, Sc and Sm. It has been noticed a relative and a slight clusterization of the analyzed items on the ratios of concentrations Na/Mn, La/Sc and La/Sm.
