Ismailia Canal is a vital fresh water stream flows adjacent to the Egyptian Atomic Energy facilities and in the neighbourhood of important factories. Some cities, characterized with relatively high population density are also located directly on the two banks of the canal and fully dependent on the canal water. The impacts of radionuclide presented in the environment may be induced due to; (a) man made release of artificial radio nuclides and/or (b) due to the naturally occurring radio nuclides. It is very important to construct models depending on experimental data to predict the transfer mechanisms of radionuclide into the environment components. The present work is a brief review of pr-studies carried out on Ismailia Canal, Egypt, water ecosystem. Ismailia Canal water body is a bicarbonate stream with slight seasonal variations in its water chemical constituents.
