In situ gamma and laboratory spectrometric measurements have been performed to characterise the natural radiation that emitted from the stream sediment and cataclastic rocks in Wadi Abu Rusheid, Southeastern Desert, Egypt. The results allowed us to delineate the origins and distributions of these natural radionuclides on the study area. Consequently, it can be possible to avoid any possible environmental impacts from these rocks and/or raw materials of high intensity of natural radiation sources. In situ gamma and laboratory spectrometric measurements illustrate that the natural radioactivity in Abu Rusheid area are very high, because this area contains a distinctive occurrence for uranium mineralization. Measured radioelement values for stream sediment and cataclastic rocks are higher than the recommended values for safety if used as building materials.
