impacts of radionuclides, in aquatic and marine environments, as
numerous aquatic species can move over considerable distances than
terrestrial species. Using specific simulating modeling code (
RESRAD-BIOTA 1.5), some biological and environmental impacts
factors such as Biota Concentration Guide BCG and the tissue of
concentration of aquatic animals, which are determined when exposing
to some radionuclides (40K and Uranium series) at the selected area of
Abou- Qir bay. The study showed that there is an increase in mean
average value of 40K at the selected area of Abou-Qir bay ( 16.58 Bq/l).
This can attributed to the location of Abou-Qir fertilizer company at
studying area. Also the results showed that the different aquatic
animals have Highest BCG (Biota Concentration Guide) value in case
of U-238 than U-235,U-234 and U-233. On the other hand, the study
showed that the highest value of tissue concentration of aquatic
animals was 0.15 Bq/Kg, this value related to the increase in mean
average value of radioactivity of K-40 which obtained in the selected
area at Abou-Qir Bay.
