摘要：
Results of systematic long-term measurements of Sr-90 and Cs-137 in surface seawater, performed at four locations along the Croatian coast of the Adriatic Sea, are summarized. Observed trends in annual mean activity concentrations are discussed. Sr-90 and Cs-137 fallout activities affect seawater activity, the coefficient of correlation between Sr-90 fallout activity and Sr-90 seawater activity being 0.72. No significant variations of Sr-90 mean residence time in the sea-mixed layer on different locations were found. From 1978-1985, the Cs-137:Sr-90 activity ratio in seawater was 1.52 +/- 0.40. In May 1986, as the consequence of the Chernobyl nuclear accident, this radio increased to 92.4 +/- 58.2.
