摘要：

alpha-Al2O3 is one of the most important materials for thermoluminescence dosimetry. The thermoluminescent features are strongly affected by impurities, which were investigated with the non-destructive method of prompt-gamma activation analysis (PGAA). Impurities in four samples of thermoluminescent alumina materials were investigated. The precision and reproducibility of the PGAA method were also tested on standard samples spiked with B, Na, S, Cl, Fe, Cu and Ag.
