TL;DR: In this paper, the distribution of natural radionuclide γ-ray activities and their respective annual effective dose rates, produced by 40 K, 238 U, 226 Ra, 235 U and 232 Th, were determined for granite samples collected along the road of Idfu - Marsa Alam in eastern desert of Egypt.
Abstract: The distribution of natural radionuclide γ-ray activities and their respective annual effective dose rates, produced by 40 K, 238 U, 226 Ra, 235 U and 232 Th, were determined for granite samples collected along the road of Idfu - Marsa Alam in eastern desert of Egypt. This subject is important in environmental radiological protection, since granites are widely used as building material. The variation in concentration of radionuclides for thirty granite samples was determined. A HPGe spectrometer was used for quantification of gamma emitting radionuclides in the sediments. All sediments contained radionuclides from the uranium and thorium series as well as 40 K. 238 U concentrations in the samples ranged (from 12.03±0.88 to 19.34±1.41 Bq.kg - 1 ), 235 U (from 1.16±0.11 to 4.83±0.44, Bq.kg -1 ), 226 Ra (from 9.69±0.82 to 18.97±1.33 Bq.kg -1 ), 228 Ra ranged (from 10.24±0.70 to 17.35±1.29) 232 Th range (from 9.99±0.67 to l7.65±1.23 Bq.kg -1 ) and 40 K (from 298.58±21.74 to 955.78±69.58 Bq.kg -1 ). Radium-equivalent activities (Raeq) in addition to the internal hazard index (Hin) have also been determined. Granite samples Raeq varies between 49.05 and 113.39 Bq.kg -1 . The total absorbed dose rates in air calculated from the concentrations of the three radionuclides ranged from 24.24 to 58.05 nGy.h -1 and the external annual effective dose rate of the areas were determined to be between 0.12 and 0.28 mSv.y -1 . The results can be considered as base values for distribution of natural radionuclides in the region and will be used as reference information to assess any changes in the radioactive background level due to geological processes.

Abstract: The aim of this study is to determine the transfer factor soil-to-plant and to assess the concentration level of natural and artificial radionuclide (238U, 226Ra, 228Ra, 232Th, 40K and 137Cs) in samples from Saluga and Ghazal Protectorate area in Aswan, Egypt, by using High Pure Germanium detector (HPGe) Environmental Radioactivity Measurements Labrotary in faculty of science Qena. Reported values for natural radionuclides ranged from 8.81 ± 0.64 to 28.88 ± 2.10, from 6.98 ± 0.51 to 26.01 ± 1.89, from 12.29 ± 0.89 to 33.32 ± 2.43, from 12.53 ± 0.91 to 32.81 ± 2.39 and from 383.90 ± 27.95 to 711.98 ± 51.83 Bq.kg-1 for 238U, 226Ra, 228Ra, 232Th and 40K, respectively. 137Cs activity concentration was found to be in the range from 0.36 ± 0.03 to 9.73 ± 0.71 Bq.kg-1 and was calculated through transfer factor TF reported in this article.
