Descrição: Activity levels of the natural ( 238 U, 232 Th, 226 Ra, and 40 K) and artificial ( 137 Cs) radionuclides in surface soil samples collected from different areas of Libya, especially the southern and central provinces, including Valley Rwagh, which is in a mountainous region in Al-Jufra Oasis amid the Libyan desert, 600 km southeast of Tripoli, and in which there are stores of various weapons, were determined using a gamma-ray spectrometer with a HPGe detector. The average activity concentrations of 238 U, 232 Th, 226 Ra, and 40 K were measured as 87 ± 11, 202 ± 36, 121 ± 19, and 73 ± 3 Bq kg -1 , respectively. The activity levels of artificial radionuclide 137 Cs measured in soil samples were below the detection limit. The average concentrations of radon in soil and air were estimated as 103 kBq m -3 and 327 Bq m -3 , respectively. The average values of outdoor absorbed gamma dose rate and the corresponding annual effective dose rate from external exposure, annual effective dose rate from inhalation of radon, and lifetime cancer risk estimated for assessing the radiological impacts caused by ionizing radiation emitted from these radionuclides on the population in the region were found to be 165 nGy h -1 , 203 μSv y -1 , 3096 μSv y -1 , and 7 × 10 -4 , respectively.
