Preliminary results of natural radioactivity measurements in the southern part of Ethiopia

The paper presents the first results of natural radioactivity measurements in the Southern part of Ethiopia (Bale Zone-Oromiya Regional State). The preliminary results indicate that radiation levels in the mining areas of Kallido Mountain are elevated compared with those in the town of Negele Borena (background area). Both external gamma radiation and alpha surface contamination levels are significantly elevated above local background levels.
