title: Occurrence of210Po in marine macroalgae inhabiting a coastal nuclear zone, southeast coast of India.
abstract: The activity concentration of210Po 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 maximum210Po concentration and chlorophytes the minimum. The average210Po 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 to210Po was calculated to be well below the benchmark dose limit of 10 μGy h-1.
