Perna pernamussels and shrimp, Xiphopenaeus kroyeri,collected in August 2010 at Ilha Grande Bay, a tropical estuary in the state of Rio de Janeiro coast, were analyzed for 210Po contents. The method for the determination of 210Po consisted of spontaneous deposition on copper discs, followed by alpha counting. The average values found for the activity concentration of 210Po in Perna pernamussels were 105.1 Bq kg−1 (8 cm size) and 98.4 Bq kg−1 (4 cm size), wet basis. For the shrimp, the values varied from 26.17 Bq kg−1 to 29.56 Bq kg−1 (wet basis) for the tail muscle, and from 274.49 Bq kg−1 to 428.82 Bq kg−1 (wet basis) for the head.
