NATURAL RADIOACTIVITY OF CLAY AND SANDY SOILS AND THE EXPOSURE DOSES OF THE POPULATION IN REGIONS HEET AND INSHASS (EGYPT)
In the present work, the results of the studying of naturally occuring radioactivity of clay and sandy soils in two different places in Egypt. Determined values of the absorbed and effective doses of exposed population in these places, due to the contents of <sup>226</sup>Ra, <sup>232</sup>Th and <sup>40</sup>K in soils.
