Estimation of 210Po in marine organisms at Mumbai, India

210Po was estimated in the edible muscle of fifteen different marine species collected from Trans-Thane Creek area (Trombay) and Thane. Daily intake of 210Po and its radiation dose to human beings due to consumption of marine organisms collected from this particular area were assessed. Estimation of 210Po was carried out using radiochemical separation and alpha spectrometric technique. The concentration of 210Po was found to vary from 0.18 to 10.9 Bq kg-1wet wt in different biota species and maximum concentrations were observed in bivalves.The daily intake and individual dose of 210Po to human beings through biota consumption was calculated and found to be 31.89mBq d-1 and 19.44μSv yr-1 respectively.
