Description
  • The distribution of natural radionuclides in the main rock-types: granodiorites (granites), biotite-gneisses, black shales and amphibolites from the Malé Karpaty Mts. complex was studied in samples collected from two boreholes. The samples were analyzed by means of gamma-ray spectrometry. The concentrations of 238U, 232Th and 40K were found to be within the range of 0.091-37.800 mg/kg (238U), 0.534-13.234 mg/kg (232Th), and 0.116-5.162 mg/kg (40K). The highest average 238U concentration was in black shale, highest average 232Th concentration in granodiorite-granite and highest average 40K concentration in granodiorite - granite as well. Activities of 238U were determined within the range of 1.092-48.960 Bq/kg (with exception of one anomalous value ? 453.6 Bq/kg), activities of 232Th within the range of 2.189 ? 54.298 Bq/kg and activities of 40K within the range of 30.933 ? 1,376.499 Bq/kg. It is considered that the source of 238U and 232Th (and partially also of 40K) is in the granitoide intrusion.
