Abstract
The study aimed to determine the radioactivity concentration and
radiological assessment in Soil samples around Abu Jubayha, Eastern Nuba
Mountains was made by gamma spectrometry technique equipped with NaI (Tl). The
result of activity concentration of 226Ra, 232Th and 40K were varied from 23.58 ±7.86
(18.02-29.14), 36.14 ± 5.17 (32.48 -39.79) and 381.88± 127.43 (291.78 - 417.99)
Bqkg-1 respectively. Absorbed dose rate and annual effective dose were estimated to
evaluate radiological hazards and were varied from 39.47±8.6 (33.38-45.55) nGyh-
1and 38.43±10.56 (40.97-55.9)µSvy-1, respectively .Upon comparing the results with
global data, they were found to be within the recommended limits. The result will be
serving as a base line for future studies. GIS apocalyptic map was originated and has
shown that there were some hot spots with high activity distribution and
concentrations of the measured radionuclide and similarly Dose Rate.
