Concentration of 210Po was determined in the muscle and bone of 15 species of fishes collected from river kaveri. The concentration of 210Pb was ranged between 0.47 Bq/Kg and 2.9 Bq/Kg and in muscle between 2.5 Bq/Kg and 8.4 Bq/Kg in bone. The 210Pb concentration recorded maximum in muscle of carnivorous fish Hetcropheastes fossilis (2.9 Bq/Kg) and minimum in the Cirrhinus mrigal (0.47 Bq/Kg) Similarly 210Pb was found maximum in bones of carnivorous fishes Glossogobius giuris (8.4 Bq/Kg). https://www.biotech-asia.org/vol5no2/relationship-of-lead-210-in-activity-and-different-feeding-habit-of-fresh-water-fishes-in-river-kaveri-tiruchirappallitamil-nadu/ Polonium - 210; Lead - 210; carnivorous fishes;
