We study radiation exposure resulting from the consumption of farm-raised freshwater fish species that form an essential part of the Bangladeshi diet. The levels of radioactivity in the human diet are of particular concern, requiring assessment of possible radiological risks to human health. Therefore, a comprehensive study was carried out to determine the radioactivity levels ( 226 Ra,  228 Ra, and  40 K) in fifteen commonly available varieties of farm-raised fishes. The gamma-ray spectroscopic analysis showed the presence of radionuclides of  226 Ra,  228 Ra, and  40 K in all studied fishes, but varying degrees. The highest radioactivity levels of  226 Ra,  40 K, and  228 Ra were observed in Rui (Labeo rohita) and Tilapia ( Oreochromis mossambicus ) with values of 8.50 ± 0.30, 513.28 ± 1.59, and 7.41 ± 0.15 Bqkg −1 , respectively. The respective radioactivity levels were lowest in Silver carp ( Hypophthalmichthys molitrix ), Mola ( Amblypharyngodon mola ), and Koi ( Anabas testudineus ) with values of 0.83 ± 0.38, 171.07 ± 1.60, and 0.62 ± 0.30 Bqkg −1 . The doses for  226 Ra,  228 Ra, and  40 K due to consumption of a kilogram of farm fish were assessed and range from 5.56 (Sarputi –  Puntius sarana ) to 54.36 µSvy –1  (Rui –  Labeo rohita ), 9.77 (Koi –  A. testudineus)  to 116.79 µSvy –1  (Tilapia –  O. mossambicus ), and 24.23 (Mola –  A. mola ) to 72.69 µSvy –1  (Rui –  Labeo rohita ), respectively. In most cases, the estimated probability of an increase of cancer risk from daily intake of the farm-raised fish diet representing a minor fraction of ICRP values. Statistical analysis shows that the radioactivity and estimated radiological parameters are strongly correlated with  226 Ra and  228 Ra, while weakly correlated to  40 K, suggesting that radiological risk is basically associated and controlled by the activity levels of uranium and thorium series radionuclides.
