The activity concentrations of 210Po and 210Pb in four species of fish (Atule mate, Pampus argenteus, Cynoglossus macrolepidotus and Sillago sihama) caught in the coastal water of Kuala Selangor was measured. The concentrations of 210Po and 210Pb in tissues ranged from 0.47 Bq kg-1 to 68.10 Bq kg-1 dry weight and 0.65 Bq kg-1 to 23.10 Bq kg-1 dry weight, respectively. The different levels of activity concentrations observed in different species may be due to differences in feeding habits and metabolic rates. Lower concentration factors of 210Po in fish tissues probably indicate that the accumulation of 210Po in the analyzed fish tissues is low and might be the result of low 210Po in the study area. The annual intake of 210Po and 210Pb via fish consumption in Malaysia are consequently estimated to be 0.28 Bq d-1 person-1 and 0.09 Bq d-1 person-1, respectively. This suggests that the dose of both radionuclides received by Malaysian population due to low consumption of fish.


Kepekatan aktiviti 210Po dan 210Pb bagi empat spesies ikan (Atule mate, Pampus argenteus, Cynoglossus macrolepidotus and Sillago sihama) yang diperolehi di perairan Kuala Selangor ditentukan. Kepekatan 210Po dan 210Pb dalam tisu berjulat dari 0.47 Bq kg-1 - 68.10 Bq kg-1 berat kering dan 0.65 Bq kg-1 - 23.10 Bq kg-1 berat kering, masing-masing. Perbezaan aras kepekatan aktiviti yang diperolehi bagi spesies yang berbeza mungkin disebabkan oleh tingkahlaku pemakanan dan kadar metabolisma yang berbeza. Faktor kepekatan 210Po dalam tisu adalah rendah disebabkan oleh akumulasi 210Po dalam tisu ikan yang dianalisis rendah dan berkait rapat dengan keputusan 210Po yang diperolehi dalam turus air di kawasan kajian. Kadar pengambilan tahunan 210Po dan 210Pb melalui penggunaan ikan di Malaysia adalah dianggarkan 0.28 Bq hari-1 seorang-1 and 0.09 Bq hari-1 seorang-1, masing-masing. Ini menyarankan dos melalui kedua-dua nuklid ini yang diterima oleh penduduk Malaysia adalah rendah disebabkan pengambilan ikan yang rendah.
