摘要

Soil from cambisols sites in Northern Montenegro were analyzed on 235U, 238U, 226Ra, 232Th and 40K activity which are found to range up to 2.72, 61.9, 41.2, 54.7 and 716 Bq kg−1, respectively. The results for 226Ra, 232Th and 40K are combined with ones obtained in previous studies and used in statistical analysis which showed a strong positive correlation 226Ra and 232Th activity in Montenegro soils. Discriminant Analysis is used to separate the regions and soil types by radionuclide concentrations and absorbed dose rate in air, which is found to be higher than the worldwide average for exposure outdoors.
