Abstract: The article presents the specific activities of natural radioactive nuclides in soil samples from Upper Egypt. The samples had been measured within the last ten years and the results were compared with others from some countries. The mean activity level of the natural radionuclides 226Ra, 232Th and 40k is 21.4, 14.6 and 663.1 Bqkg-1, respectively. These values agree with values reported elsewhere in the country and other countries. The paper includes available results of hazard indices values which indicate that there are no excessive exposures for inhabitants. These data are important for radiation protection purposes.
