A Study on the Activity Concentration of Po-210 in the Marine Environment of the Kapar Coastal area

The distribution of a natural radionuclide (po-210) in seawater, total suspended solid (tss), sediment and marine organisms was quantified using alpha spectrometry at the coastal area of kapar, malaysia. it was observed that the po-210 activity in tss was much higher than that of water and sediment samples. the ranges of po-210 activity in organism samples were 4.12±0.11 bqkg^-1 to 7.49±0.14 bqkg^-1 (arius maculatus), 8.66±0.28 bqkg^-1 to 44.47±0.83 bqkg^-1 (penaeus merguiensis), 55.59±1.07 bqkg-1 to 161.68±4.21 bqkg^-1 (anadara granosa) and 45.70±1.77 bqkg^-1 to 96.44±2.19 bqkg^-1 (perna viridis). there are significant correlations between the total weight and po-210 concentration for all the organisms sampled. the concentration factors of po-210 for the organisms calculated were 1851.42 (arius maculatus), 14296.58 (penaeus merguiensis), 95314.84 (anadara granosa) and 27128.18 (perna viridis). therefore, it can be assumed that mollusks can contribute a higher radiation to seafood consumers in the coastal area of kapar.
