Abstract
On the basis of extensive sampling, marine environment gamma spectrometry, laboratory [analysis, data evaluation and comparison with other Egyptian, Mediterranean and international (data, the following conclusions and assessment can be drawn.
The distribution, transportation and bioaccumulation of the detected radionuclides along lie Egyptian Mediterranean coast have been investigated. The variations of radionuclide oncentrations have been quantified, where appropriate and source terms have been identified or jested.
Radioactivity in surface seawater along the Egyptian Mediterranean coast has been cussed. 40K was found to be the only radioisotope which has been detected in all surface awater samples through all the monitoring period. The lower average concentrations of 40K ve been detected in the stations, which received low saline water discharged from inland ;s such as the Nile River branches (Rashid and Damietta), outfalls and outlets. These ions were El-Mex, Shatby and the area extending from El-Maadia to El-Gamil. 40K is an li metal, which behaves as a true soluble element and varies in proportion to salinity, erefore, it is understandable that there is a relation between the concentration of 40K and the ity in the surface seawater.
The highest concentrations of 40K have been detected at Ras El-Hekma, Sidi Abd El-El-Bitash and Sidi Gaber. All the surface seawater of these stations has salinity around
pH, temperature, dissolved oxygen, salinity and specific conductivity of surface seawater
been determined using the 600XL Multi-Parameters Water Quality Monitor (CTD).
sparency has been determined using seccki disc. Salinity has shown positive correlation and
trend with 40K concentrations in surface seawater with correlation coefficient r = 0.64.
