Distribution of 238U, 226Ra and 210Pb and 210Po in sediment and in tissues of A. granosa and B. Boddaerti from coastal waters of Bombay was estimated. The levels of these natural radionuclides were highest in the deposited sediment (20 ± 4.84, 43.6 ± 12.2, 356 ± 68.8 and 784.1 ± 174.2 mBq g-1 dry sediment respectively for 238U, 226Ra and 210Pb and 210Po. Concentration of 210Po was significantly higher compared to other nuclides in the soft tissues of A. granosa. The levels of 210Pb and 210Po were higher in tissues of A. granosa than in those of B. Boddaerti from the same environment. Higher ratio of 210Po and 210Pb activity in the clam and fish suggests 210Po is more reactive than its precursor 210Pb and also there is a distinct bioaccumulation of unsupported 210Po than that supported by 210Pb.
