Description

The concentration of 210Po, an alpha emitter of the natural uranium series was measured in some commercial seaweeds, collected from Krusadai island, the south east coast of Tamil Nadu. The concentration of 210Po in water and sediment samples was found to be 2.80 mBq/l and 36.2 Bq/kg respectively. The 210Po was observed to be non-uniformly distributed among the seaweeds, which maintained the following descending order: Ulva reticulata (30.0 Bq/kg > Cystophyllum murictum (24.9 Bq/kg) > Sargassum wightti (22.1 Bq/kg) > Sargassum ilicifolium (19.6 Bq/kg) > Hypnea valentiae (15.09 Bq/kg) > Gracilaria follifera (14.87 Bq/kg) > Gracilaria edulis (10.12 Bq/kg) > Turbinaria conoides (8.5 Bq/kg) > Gelidiella acerosa (5.80 Bq/kg). The general range of CFs for the macro algae varies between 103 and 104. The distribution of 210Po in the seaweeds and its relation to the protein content is discussed.
