In this work, the activity concentrations (radioactivity) and distributions of natural radionuclides in peat moss samples were investigated. The measurements were performed using HP-Ge detector and XRD technique. The samples represent six types of soils. The concentrations of radionuclides of 238 U, 226 Ra, 232 Th and 40 K are ranged from 17.14 to 130.83, 13.19 to 26.09, 5.33 to 25.2 and 143.26 to 600.31 Bq•kg-1 (dry weight), respectively, for the different samples. This work also highlights that no correlation has been observed between radionuclides present in the samples, which in turn reflects the random method
