Description:

The aim of the paper is to present the results of measurements of 40K, 208Tl, 212Pb, 214Pb, 214Bi and 228Ac activity concentrations of selected rocks co llected from the contact zone of the Karkonosze massif with the Szklarska Poręba schist-belt. Activity concentrations were obtained using a gamma-ray spectrometry system. Determined activity concentrations of 40K and nuclides from 238U and 232Th series in measured samples were compared with average activity concentrations of these radionuclides in the continental crust and in the soil and with data concerning investigated area available in the selected literature. In all rock samples very high activity concentrations associated with decay of 232Th and 238U series were observed. These values twice exceed the average activity concentrations refer to continental crust and are distinctly higher than activity concentrations measured in typical rocks of the Izera block., Aleksandra Bieda and Grzegorz Lizurek., and Obsahuje bibliografické odkazy
