Description
The migration of radionuclides in the aquatic components is qualitatively described by the concentration factors (CFs). Estimations are performed for 271 marine samples of sediments, macroalgae, molluscs and fish collected between the Danube mouths and Mangalia during 1983-1991. Natural and artificial radionuclides are studied (40 K, 228 Ac, 226 Ra,60 Co, 110m Ag, 106 Ru, 134 Cs, 137 Cs).. For sediment samples, CFs are at least of several hundreds order for Ac, Ra, Ru,, Cs and of tens order for K. Living components have availabilities of tens order for K, Ac, Ra, Cs. Molluscs have traces of Co, Ag, Ru. Green alga Bryopsis plumosa substantially differentiates Ac, Ra. The fish Engraulis encrasicolus ponticus presents a relative increased concentration of radiocesium in 1986. (author) 1 tab., 30 refs
