| Abstract: | After irradiation and dissolution of the samples (minerals, rocks etc.), elemental tellurium is precipitated, redissolved, extracted for its diethyldithiocarbamate, and finally reduced again for measurement of the 132Te 228-keV γ-peak. The chemical yield is 75% and the lower limit of determination is 2 × 10-7 g U. |
