Abstract

90Sr, 210 Pb, 210Po and Ra isotopes were determined in macroalgae Ceramium rubrum, Cystoseira crinita, Ulva rigida, Cladophora vagabunda, Enteromorpha intestinalis and in mussels Mytilus galloprovincialis collected from the Bulgarian Black Sea coast. Radiochemical separation was made by a fast and reproducible procedure based on a calcium phosphate precipitation technique. The obtained results for macroalgae vary in the interval 0.23–0.85 Bq kg−1 for 90Sr, 2.2–10.6 Bq kg−1 for 210Pb, 1.2–9.7 Bq kg−1 for 210Po and 1.9–13.2 Bq kg−1 for Ra isotopes. Data obtained for mussels demonstrate similar abilities in the accumulation of 90Sr, 210Pb and Ra isotopes.
