Abstract
The specific concentration and activity levels of six main coastal
regions (all lies along the Western Coast of Suez Gulf) where
studied. Twenty-two soil samples were collected from the
investigated regions. These regions are Ain Sokhina, Al Zafrana,
Ras Gharib, Ras Shokeir, Gebel El Zeit and Hurghada. Using
HPGe γ-ray spectrometry, analysis of the collected samples has
been carried out to determine the concentrations of 226Ra, 232Th
and 40K in samples. Moreover, radon exhalation rates, effective
radium content and radon emanation power were measured by
using SSNTDs in the form of CR-39. The obtained average
concentrations values of 226Ra, 232Th and 40K were lower than the
national and worldwide average values also the average radium
equivalent activity value was below the defined limit of 370
Bq/kg. The external and internal hazard indices were found to be
less than 1, indicating low radiation doses. Also, it was found that
samples have exhalation rates comparable with the worldwide
average values. In general the activity levels of the studied regions
are within the worldwide average and the public received doses
within the safe limit of exposure.
