The activity concentration of ²¹⁰Po in 26 species of marine macroalgae found along coast near to a nuclear installation in southeast coast of India was studied. Phaeophytes were found to accumulate the maximum ²¹⁰Po concentration and chlorophytes the minimum. The average ²¹⁰Po activity concentration values in the three groups were 6.2 ± 2.5 Bq kg⁻¹ (Chlorophyta), 14.4 ± 5.2 Bq kg⁻¹ (Phaeophyta) and 11.3 ± 3.9 Bq kg⁻¹ (Rhodophyta). A statistically significant variation in accumulation was found between groups (p < 0.05). The un-weighted dose rate to these algae due to ²¹⁰Po was calculated to be well below the benchmark dose limit of 10 μGy h⁻¹.
