Comparison of two spectrometric counting modes for fast analysis of selected radionuclides activity

The two counting modes: a normal with a single HPGE detector and second with the additional anti-Compton shield of the annular NaI(Tl) detector have been compared for fast determination of the activity concentration of thorium (232)Th in the building materials. The (232)Th activity concentration was...

description The two counting modes: a normal with a single HPGE detector and second with the additional anti-Compton shield of the annular NaI(Tl) detector have been compared for fast determination of the activity concentration of thorium (232)Th in the building materials. The (232)Th activity concentration was calculated by measurement of its decay products: (212)Pb, (212)Bi and (208)Tl as well (228)Ac content. Although the Compton suppression mode applied in gamma spectrometry systems in general increase sensitivity of the analysis, but in case of 583 keV the most abundant (208)Tl γ-line, the significant reduction of photon counting rate was observed.
