The activity concentration of 210 Po and 210 Pb were determined in the edible muscle tissues of 20 fish species collected from Pulicat Lagoon, south east of India. The concentrations were found to vary between 38.3 Bq.kg -[1] - 109.3 Bq.kg -[1] and 0.72 Bq.kg -[1] - 2.7 Bq.kg -[1] for [210] Po and [210] Pb respectively. These variations in the [210] Po and [210] Pb content in different species were probably due to differences in metabolism and feeding patterns. Appropriate conversion factors were used to derive the committed effective dose for human consumers, which were found to be 73.3 1 - 209.1 μSv.yr -1 and 2.2 - 19.3 μSv.yr -1 for 210 Po and 210 Pb respectively.
