  • Title: Uptake of 210Pb and 210Po by Brazilian Bunodosoma caissarum Corrêa, 1964 (cnidaria, actinidae).
    Author: Gouvea RC, Santos PL, Dutra IR, Gouvea VA.
    Journal: Sci Total Environ; 1989 Jul 01; 83(1-2):181-3. PubMed ID: 2781266.
    Abstract:
    Bunodosoma caissarum, a carnivorous marine species exclusive to the Brazilian southern coast, recognized as a sensitive bioindicator of artificial radioactive pollution, also shows a great capacity for concentrating natural alpha-emitters. The authors have measured the alpha-emitters 210Po and its precursor 210Pb in this animal. The average concentrations found are greater (by a factor of 4.6) for 210Po measured in samples gathered on Ponta Negra Beach (protected outer coast) than the values obtained in specimens collected on Boa Viagem Beach (closed bay) along the Rio de Janeiro coast, Brazil. The same was also found for 210Pb (a factor of 2.5).
