| Abstract: | A survey study on natural radioactivity of 214Pb, 214Bi
in 238U series and 208Tl, 228Ac in 232Th
series in granite rock collected from the state of southern Kordofan (Kadugli),
Sudan
has been carried out by using g-ray
spectroscopy technique. The gamma-ray spectra have been measured for daughter
decaying of 238U and 232Th series. Elemental and activity
concentrations were found to be 1.41±0.02 ppm and 17.41±0.19 Bqkg-1 for 214Pb,
1.66±0.02 ppm and 25.60±0.21 Bqkg-1 for 214Bi and
9.56±0.11 ppm and 38.81±0.43 Bqkg-1 for 208Tl,
8.55±0.06 ppm and 34.71±0.23 Bqkg-1for 228Ac, respectively.
Moreover, average activity concentrations of these radio-nuclides for granite
samples have been compared with the typical values of different countries. |
