Abstract

Práce se zabývá gamaspektrometrickou a minerálně-chemickou charakteristikou popílků vzniklých spalováním uhlí v oslavanské elektrárně a uhelných jílovců se zvýšenou radioaktivitou boskovické brázdy

Abstract (in English)

The concentration of K, U, Th was measured by a portable gamma spectrometer on localities of radioactive anomaly (coal-bearing sediments and a slag dump) in the southern part of the Boskovice furrow, in the Rosice-Oslavany basin in Oslavany. Samples from both localities were measured by more precise laboratory gamma spectrometer and analyzed on an electron microprobe. The comparison of U and Th concentration among the samples of coal-bearing sediments and the slag samples (products of coal burning) reveal that the coal-bearing samples contain higher U concentration and lower Th than the slag samples. It was also determined that the U is bond into a limonite vein cutting the coal-bearing shale. The U is not concentrated into any of the phase found in glass of the slag, but it is distributed evenly throughout the glass.
