Natural Radioactivity Concentration and RadiologicalAssessment in Soil Samples Around Abu Jubayha, Eastern Nuba Mountain
Journal Title: Saudi Journal of Engineering and Technology - Year 2017, Vol 2, Issue 9
Abstract
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.
