Abstract

The biological concentration factors for the system pilchard/sea-water for 90Sr and 137Cs are presented and discussed. The 90St concentration factor was constant, whereas the concentration factor for 137Cs steadily increased after the Chernobyl accident. An UNSCFAR model was used to describp 90Sr transfer from fallout deposition to pilchards. Tire transfer coefficient was calculated to be 1.85 x 10-3 Bq yr kg-1/(Bq-2). The dose incurred by pilchard consumption was estimated for the Croatian population, the annual collective equivalent dose being less than 0.1 Sv.
