Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="country-region"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place"> As a part of national survey to evaluate natural radioactivity in the environment, concentration levels of natural radioactivity have been analyzed from more than 108<b style=""> </b>environmental samples taken from <i style="">wadi Allaqi</i> area, south Egypt. The distribution of naturally occurring radionuclides of <sup>226</sup>Ra, <sup>232</sup>Th and <sup>40</sup>K in the samples (soil, granite, grass and water) have been measured using a high purity germanium detector. The specific activities in these samples, having a radium equivalent activity of less than 370 Bq.kg<sup>-1</sup>, when evaluated for radiological effects show that all samples meet the external gamma-ray dose limitation of 1.5 mSv.y<sup>-1</sup>. The data presented here will serve as a baseline survey for primordial radionuclide concentrations in igneous and sediment of the area. </smarttagtype></smarttagtype>
