Abstract

The natural and artificial radioactivity of the brown alga Cystoseira barbata samples collected on the Romanian Black Sea coast in 1996 is reported. The results on ¹³⁷Cs were obtained through gamma-spectrometry, on ⁹⁰Sr by beta-counting of the ⁹⁰Y oxalate precipitated after strontium separation, on ²²⁶Ra 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 barbara may be used as a bioindicator for radioactive contamination of the coastal waters.
