Abstract

Using an experimental technique (NaI(Tl)-gamma spectroscopy) the natural radioactivity emanating from a mineral soil which is in use in far-flung areas of Ethiopia was determined. The results of the experiment were converted in to radiation dose units and it is compared with internationally set standards for a public. The calculated average absorbed dose rate in air due to gamma ray from the mineral soil activity, likewise the average hazard indexes obtained for both external and internal exposure do not exceeded the limits set by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR). Therefore the mineral soil does not pose a threat to the public.
