Abstract
    The natural and artificial radioactivity of the brown algaCystoseira barbata samples collected on the Romanian Black Sea coast in 1996 is reported. The results on137Cs were obtained through gamma-spectrometry, on90Sr by beta-counting of the90Y oxalate precipitated after strontium separation, on226Ra by the emanation method, while the concentrations of U, Th, Pu and Am isotopes were obtained through radiochemical separations using tracers followed by alpha-spectrometry counting of the stainless steel discs after electrodeposition. These results add further evidence that Cystoseira barbata may be used as a bioindicator for radioactive contamination of the coastal waters.
