Přirozená radioaktivita horninového prostředí v českých jeskyních zpřístupněných pro veřejnost (Bozkovské dolomitové jeskyně, Koněpruské jeskyně, Chýnovská jeskyně)

Original language description

Concentrations of natural radioactive elements (K, U and Th) were measured using a field gamma-ray spectrometer GS-256 in the rocks in the Bozkov Dolomite Caves, Koněprusy Caves, and Chýnov Cave. Concentrations of these elements were converted to the mass activity of 226Ra equivalent (am) in order to express gamma-ray activity at the studied sites. Average values of am of metamorphic rocks (calcite marbles and quartzites), sinters, and cave soils in the Bozkov Dolomite Caves are 99, 70, and 128 Bq.kg-1,respectively. Marbles and cave soils in certain parts of the Bozkov Dolomite Caves (so-called Nová Cave) have increased contents of uranium (up to 11 ppm U in marbles). The monitored zones of the Koněprusy Caves are characterized by low average values am of Devonian limestones and also sinters (70 and 54 Bq.kg-1, respectively). Average am value of Silurian dolostones in the Koněprusy Caves area is 138 Bq.kg-1 (up to 12 ppm U in the rocks). Relatively high natural radioactivity of cave s
