Radionuclide concentrations of uranium (238U), thorium (232Th) and potassium (40K) maintained in 10 phosphate ore and 5 fertilizer samples were measured using a high-purity germanium detector. The concentrations of these radionuclides in the phosphate ore samples were relatively high for 226Ra at 871.37±91.90Bqkg−1 and relatively low for 232Th and 40K at 19.21±2.42Bqkg−1 and 176.06±17.66Bqkg−1, respectively...
