The present work is carried out to obtain quantitative information of some natural radioactive materials and heavy metals in water and sediment samples along the Alexandria Coastline, as a step to construct the baseline map of the background radioactivity level in the Egyptian environment and also as a base data to assess the future physicochemical changes of surface coastal water and sediment Here the authors present concentrations in seawater and calculated in situ bioconcentration factors for [sup 90]Sr, [sup ]Cs, and [sup +]Pu (the three most important radionuclides in Arctic risk assessment models) in macroalgae, crustaceans, bivalve molluscs, sea birds, and marine mammals as well as sediment K[sub d] values for 13
Concentrations of various radionuclides in abiotic and biotic samples, environmental distribution coefficients (Kds) and concentration factors (CFs), as well as experimentally-derived CFs in marine biota as radioecological bioindicators have been assessed and stored for a national data base and for international uses. 3. RESULTS A literature review shows that both freshwater and marine plankton have trace element and radionuclide concentration factors (relative to water) of up to 10/sup 4/. In the years , considerable work was done on the accumulation and distribution of a variety of fission and activation products produced by the nuclear tests in the Marshall

Three radionuclides, 99 Tc, Cs, and / Pu, were used in the validation of both models. These radionuclides were chosen either to represent a long time period of measurements ( Cs), or to exhibit a range of behaviours in the marine environment, from a strong affinity to sediment (/ Pu) to high spatial dispersion (99 Tc).
Sediment Kds and concentration factors for radionuclides in the marine environment A knowledge driven stochastic active contour model (KDS-SNAKE) for contour finding of distinct features Revisão integrativa: método de pesquisa para a incorporação de evidências na Much interest has been generated in assessing the possible risks of contamination for humans and marine life resulting from the dumping of nuclear waste in Arctic Seas by the former Soviet Union.
Models are being used to predict the transport of radionuclides released from the dumping grounds. A key parameter in these models is the partition coefficient representing the uptake potential of assessment of radiation impacts on human beings and the environment.

Not only do the oceans cover 70% of the Earth’s surface but, with an average depth of about 4 km, they contain some × 10 21 L of water plus dissolved salts. Fresh waters are much smaller, accounting for no more than about 3% of the water on the planet; about × 10 16 L per year enters the oceans as continental runoff (1).
