Description 35-41
The contents of
natural radionuclides were measured in sand dunes samples collected from Safaga
region in the Red Sea, Egypt
by using low level gamma spectrometry. Based on the characteristic spectral
peaks, the radionuclides 226Ra, 232Th and 40K
concentrations were determined. Average activity levels for these elements are 28.82, 14.03 and 558.39 Bq kg-1.
These values are lower than the global values reported in UNSCEAR publications.
Results are discussed and compared
with the levels in sand samples from different countries. Averages of radiation
hazard parameters for the Safaga sand
dunes samples are lower than the acceptable level 370 Bq kg-1 for
radium equivalent Raeq, 1 for level index I r, the
external hazard index Hex ≤ 1 and 59 (nGy.h-1) for absorbed dose
rate. These data records the radioactivity background levels in Safaga sand
dunes samples.
