Results from gamma radiation analysis of samples of bladder-wrack, Fucus vesiculosus, growing in the aquatic environment of Swedish nuclear power plants, are presented. The concentrations of the main nuclides, viz. (sup 60)Co, (sup 58)Cu, (sup 65)Zn, (sup 54)Mn and (sup 110)Ag, are reported. Series of samples from the environment of Ringhals (at the Swedish west coast) and of Simpevarp (at the Baltic proper) were collected during the years 1979-1982 and 1981-1982, respectively. The data for (sup 60)Co and (sup 65)Zn were analysed using a model correlating the concentration of radionuclides in Fucus with the corresponding discharges. Also, on a small series of (sup 60)Co data from Simpevarp, a model was tried based on kinetic constants for uptake and elimination. The nuclide concentrations in Fucus as a function of the distance to the point of emission was also studied, as well as transfer factors for the different nuclides. Finally the accuracy which can be expected when using Fucus for checking discharges of radionuclides from a power plant is discussed. 15 refs., 6 figs., 11 tabs. (Atomindex citation 23:078837)
