ABSTRACT: Neutron activation analysis
technique of the Gd2O2S:М scintillation ceramics was
developed. The concentrations of 15 trace, minor and major elements (As, Ce,
Co, Cr, Cs, Eu, Fe, La, Sc, Tb, Zn, Zr, Pr, Gd, Na) have been measured with the
instrumental neutron activation analysis of the Gd2O2S:Pr
sample. The concentrations range of the determined elements is from 3 × 10-8 to 2.0% in mass. The determination limit of the elements was calculated to be (0.6
- 1.3 × 10-8% in mass).
