ABSTRACT: Ten soil
samples from Jabal Al Qur, Wadi Baba, and Wadi Sieh in Sinai, Egypt, were
analyzed by XRD spectroscopy. The XRD spectroscopy results indicate that the
major, minor and trace constituents varied from one sample to another. Samples
were also analyzed by HPGe gamma spectrometer to determine the activity
concentration of U-238, Th-232 series and K-40. The concentrations for 238U
ranged from 57.03 to 4220.41 Bq/kg with an average 1110.75 Bq/kg,
for 232Th, ranged from 13.55 to130.46 Bq/kg with an average 71.85
Bq/Kg. The concentrations for 40K
were in the range from 12.18 to 948.93 Bq/kg with an average value 457.09
Bq/kg. The average activity concentration values of 226Ra, 232Th,
and 40K, in all the collected samples were higher than the world
average. The radium equivalent (Req), absorbed dose rate (DR),
the effective dose rate (Deff), and hazard indices resulted due to
the natural radionuclides in soil are also calculated. The Results show that
the study area is not safe for human and environments.
