Abstract
The specific activity of 226Ra, 232Th and 40K in stream sediment samples collected from two
wadies (wadi Wizer and wadi Sharm El Bahari) was determined using gamma- ray spectrometry
using a high–purity germanium (HPGe) detector. The activity concentrations of most samples are
lower than the permissible level for uranium and thorium in both wadies, the concentration of
40K are higher than permissible level. The radium equivalent activity (Raeq) and effective dose
rate were estimated as radiation health hazards. The calculated values are lower than the recommended
limit. Further analysis has been done using NaI (TI) detector and the obtained results
are compared with those obtained by the HPGe detector. The obtained results from the two techniques
confirmed each other. The obtained result shows that the area under investigation does
not pose any significant radiation hazards and is safe for use as tourist infrastructure.
