In recent years, there has been increasing interest in the significance of natural radionuclides, particularly ²¹⁰Po, in the marine environment. ²¹⁰Po, a naturally occurring alpha emitter, accumulates in marine organisms and reflects differences in their diets. In the literature, there is no data for ²¹⁰Po and ²¹⁰Pb activity concentrations for fish species on the Turkish coast of Aegean Sea. Therefore, in this study, multiple fish species were collected from six stations seasonally on the Turkish coast of Aegean Sea and were analyzed for their ²¹⁰Po and ²¹⁰Pb content. The ²¹⁰Po and ²¹⁰Pb concentrations in the fish samples were found to vary from undetectable levels to 499±44Bqkg⁻¹ dry weight (dw) and from 1.0±0.3Bqkg⁻¹ to 35±4.0Bqkg⁻¹ (dw), respectively. There were no significant differences in the activity concentrations of ²¹⁰Po and ²¹⁰Pb in fish samples between seasons (ANOVA, P>0.05). The highest dose contribution of ²¹⁰Po to humans was calculated to be 10,530μSvyear⁻¹.
