TRITIUM RADIOACTIVITY IN THE AQUATIC ENVIRONMENT OVER ALEXANDRIA REGION, EGYPT

Tritium activity is determined by standard techniques, in samples coll ected from fresh, marine and highly saline water around Alexandria. It has been found that, the average H-3 activity is 6.32 +/- 1.17, 4.02 +/- 0.77 and 2.90 +/- 0.51 Bq.L-1 for West Elnobaria Drain, Lake Mario ute and Mediterranean coastal water, respectively. Tritium activity is found to be weakly correlated with water quality parameters; pH, diss olved O2, Oxidation Reduction Potential (ORP), conductivity, salinity and chlorinity. Auto-correlation analysis indicates that the transport phenomena for H-3 variations in fresh and saline water are not the sa me.
